A huge thanks to Boost Performance for there help on the car. I couldn't have done it with out you. Pump gas video will be uploaded soon.





Mods on the way next week-

Electric Water Pump
TSP 1-7/8 Headers
TSP True Duals
Ported FAST 102/102 from AFR

Do you have any numbers on pump gas?

I have your setup but with a TRak Cam ... I like your power numbers a lot.

I had 461hp with 385 TQ

Did you do everthing at once or do you have Cam only numbers for the LG cam?

474rwhp 422rwtq on pump

Compression is 12.0 I think

lol 12 to 1 on pump i would like to see your timing with that on 91 lol

27* on pump and it was 93 octane back from the Ltx Shootout in bowling green. I poped the lt1 there and the car was on 93 out of the gas station

yea might want to run a little less like 25 or 24 to be safe is the lower end forged?

Well considering I'm in Amarillo Tx, where the average DA is 5000ft , 7000ft in the summer time, we can run more timing.

Stock bottom end as stated in the title an the top of the thread.Thanks for the timing advice but you build your car and I'll build mine. I might know a little bit though, considering I held the bolt-on Dyno, ET and Mph record. Current LT1 N/A 6spd record holder.Now a 500HP ls1 club.

I'm not saying I know everything but I know a little.

wow that has got to be a generouse dyno for over 500 hp on a stock bottom end and stock casting heads

hats off to you though its a healthy beast either way

not saying you dont know what your doing at all congrats on your records

but a dyno chart is just that a dyno chart dont mean shit, its a tuning tool thats about it. congrats on making your magical "500" rwhp because thats all that matters in this world these days to people. lets see it trap and mph at the track thats what matters in my mind. You can have all the power in the world if you cant drive you still loose.

i cant wait to see it run like a raped ape! good luck hope you get 1 more championship! :)

For you to not know your CR and be all offended by someone asking about your timing you are right knowing little, Whatever your title of LTx title holder or runner up and if thats your goal in life to stroke yourself on LS1tech who cares your still a prideful retard.

LOL

One thing i've learned over the years, dont tell all your tricks. Its not everyday that someone cant put down a big HP Ls1. Granted a dyno is a dyno, not a racetrack and i am by no means saying it is the fastest car out there based on dyno numbers. I'm only say that my 500 hp LS1 is faster than the 400 hp LT1 i pulled out over a month ago. Since most guys cant get to 500hp NA i figured i would share a little of my info on how i got mine there.



The plan is to swap the engine in the TA with the engine in the Camaro and run her at the LSX Shootout. The LT4 only made 541 so maybe they would run similar times if i put the Faceplated t56 behind the 507hp ls1.

Nice numbers.

numbers are pretty impressive for the heads used, 12.0:1 AFR (13:1 ideal), 90/90 (not 102), 1.75" pacesetter headers (1 7/8)and catback (no cutout)

let us know how it runs... ;)

congrats...

plus the 33rwhp drop from running pump 93 is a lot, especially if you are saying you only dropped timing 1-2*

Congrats. Hopefully it'll do the #'s at the track...

MR12 is a VP motorcycle race fuel that is highly oxygenated thus the reason for 12.0 A/F. On pump gas the A/F was 12.9. Vp claims a 11% increase over pump gas in sportbikes. I had 5 gallons going to waste since I was road racing due to the car stuff at the moment.

It should run comparable numbers as my Camaro with the 541 hp lt4 motor, I would hope. That chassis has AFCO's, strange brakes, moser 9 4.71's, and 3200lb race weight. The cool thing is the LT4 aready has a LS1 t56 behind it to run the McLeod softloc clutch. So all I have to do come LSX Shootout, is drop both K-members out and swap chassis. Untill then, I have a fun street car/ daily driver.

Thanks for the complaments guys, it's been a fun first LS build!

very cool like hitting it with a baby nitrous shot:secret2:

at $25 a gallon I see :eek:

Congrats Brady!! Was really cool to see her make the power! For all you non believers its true , I helped turn wrenches on it. She's all there and pulls like a freight train! Can't wait for race season

I think I remember Brady from the old Thunder shooting days. If you are the same guy then I have no doubt the numbers are legit.

Good work!

Yeah I agree. I think that it would be a good idea to use such fuel when drag racing the car. Maybe it will ET .2 better :D

+1 on that, I dont think theres a lot of thread of stock casting, 90mm FAST, 1 3/4 headers with mufflers reaching the magical 500+ club in the dyno section!!!

Congrats!

Some plp are getting butt hurt for no reason, obviously!! Update us with track results!!

Good numbers can't wait to see it At the track.

Strong power
Please post the track results

Too bad our track is closed for the year. How do you plan on adjusting your timing before the next lsx shootout when your not fighting a 5k DA. I'm curious as to what it would dyno in good air. It does seem a little high for amarillo air. We usually see similar setups around 15-20 less then your dyno.

See you at the track next year :)

Really nice numbers

With HP Tuners and reading the plugs. I know with my XFI on my Camaro that in Amarillo the car runs in 85-90 KPA because of high altitude ( 4000-7000 DA), but when i go to Dallas and the DA is 500-1500 ft the car will automatically go into the 95-100 KPA tables. IF you look at a tune file you will find that in the 100 KPA tables it will run less timing than in the 95 or 90 KPA tables. So as soon as i go to sea level the car will automatically run less timing.

My personal opinion of why it dynoed more power than most.
1- 28K mile motor
2- more compression than most guys are willing to run
3- a great combination of all the parts working together
4- Great Tuner
5- Race Fuel



On a side note, i built a 2001 WS6 with the exact same setup, Except for a G5X3 cam, years ago back in 2007 with a friend. It dynoed 486/430 on pump gas with a cut-out, and an electric water pump. This car cam only did 436/404.

http://ls1tech.com/forums/dynamometer-results-comparisons/712347-prc-stage-2-5-5-3-heads-488-rwhp-428-rwtq.html



I went off what worked years ago and went a bigger cam with the G5X4 (244/241 .610/.607 114lsa) and more compression.

Are you reposting numbers when your new exhaust and intake come in? And if so to guess the gains ill go with 490 HP 434tq on pump gas ! :corn:

wow that has got to be a generouse dyno for over 500 hp on a stock bottom end and stock casting heads

These great numbers ALWAYS seem to come from Dynojets

I raced that 507rwhp trans am My 376ci WS6 with 799's heads, pat-G cam, and S60 rearend.. He started 2 cars ahead of me and i railed him back in @ 110mph, and it was dead even till we hit a turn, He also left before i even honked, My car makes maybe 475rwhp if that, has a iron block and S60..

makes me want to try race gas in my setup. Why didnt you run E85 in this setup?

but all and all. great setup. awesome numbers and track prov the shit out of it.

lol, I'll gladly race you again now that i have a working Tach.

I didn't start early, i rolled into to it till you hit it, then i went WOT. I wanted to make sure you started first, if anything i railed you back in then walked away.

I was going too but the 30lb injectors were already at 95% on MR12. I need a second fuel pump now as it is, but i plan on swapping to a 102/102 with the shorter injectors so i'll upgrad then.

My camaro has 60lb injectors with twin pumps on E85.

Im down to run again,
Since it wasnt a fair race to start with, starting to cars ahead of me, and u railed me in somehow?? Lol

Thats a sweet setup. Ever thing about steping up to the g6x3 cam?

okay. I the reason i ask is i am now running E85. Single fuel pump and 60lbs injectors. i have not seen a problem with fuel supply yet. whats the reason for the twin pump's. I am all ears.

my set is close to your's but not really

going to try a vic intake and rod bolts this winter. it loves to spin and holds flat after 68XXrpm

Keep me posted and see if you can help me nail this tune on my ride at the track
and cant wait to see you at the fest i should be there as well. hope to see you click off a 9.XX

The weekend before i set the 10.075 record, i went 10.2XX in Dallas, and i noticed that my fuel pressure was dropping at high rpm, and the injector duty cycle was rising due to the drop in fuel pressure. I added a second fuel pump and went back to dallas the following weekend and the car went 10.075. I talked to someone , i think it was Nasty Performacne, and they said that a single walbro is rated at 600hp. I was putting down 541rwhp then adding E85 on top of that. E85 requires more fuel than pump ~30%. The sales guy laughed on the phone and stated that there was a big reason i was out of pump. So i added a second one and haven't had an issue since.

Ever consider running the new walbro 400lph pump?

No, I didn't know anything about it. I might now, after some research about it

I will be sure to recheck this next time out thanks for the heads up.

Let me share my 347 combo since I am very similar . This is in my Nova and this is in a 2600 lb raceweight , big tire car.

Ls6 block bored to 3.905
Mahle pistons with 4 cc valve reliefs
Scat 6.125 I-beam rods
Stock crank
New cam from Geoff at EPS (no track or dyne numbers as I spun a rod bearing on geoff's dyno) 238/250-.603/.596 110lsa-106cl

Heads are local shop ported 5.3 heads with 2.0 int 1.60 exhaust valves milled to 54 cc chambers.
Compression with stock gaskets the way I have ran it is 11.64/1

When I rebuild it I am thinking about going with .040 cometic gaskets for 12.2 compression. I have been running pump gas but don't mind mixing in some 112.

I have been running a truck intake with a ported 78mm tb but wan to change to a edelbrock proflow. 90mm tb but plan to try my fast 90 off my trans am before spending the money to see If it's worth it to me.

Nova went 10.24 with a cam that I got from a friend, way off for my combo.

Looking for a 9 second pass on pump gas and then plan to sell the car.


Not trying to hijack your thread Brady, just feel your combo is close to what I'm running and believe your combo is very strong. I am running a
5000 8" converter with 4.11 gears and 31x13x15 mt slicks.

Good luck with your car, look forward to seeing your results.

The numbers on the dyno used have been proven by track times, time and time again. This car is legit and was built by a great mechanic and tuned by a great tuner. Simple as that. As far as for the gains on the fuel its completely reasonible. You are basically cramming more air into the cylinder. Which in turn would be like running the car at a lower elevation. This car WILL put down the track times to coencide with the dyno numbers. And Habeebeeb, all of your shit is slow and always has been. I have no doubt that Brady busted your ass.:engarde:

Killer numbers, Brady! Get out there and race....doubters will always be doubters until they get drug :)

Nice numbers Brady. Im running the G5x4 in my car, along with all your other mods, except for the heads. I might need to consider some 5.3's from TSP.

Brady car pulls its ass of! Can't wait to hit the track with it!

Nice numbers, get some track times!!! There will always be doubters till you do. I had the same problem with my old setup, till it went 132 in the 1/4.

lol, I'll gladly race you again now that i have a working Tach.

I didn't start early, i rolled into to it till you hit it, then i went WOT. I wanted to make sure you started first, if anything i railed you back in then walked away.

even if that was the case.........which its not. who starts a run thats running into a substantial curve? Rather than waiting for the completely straight run on the other side of the curve. I am interested to know if that car runs fast in a straight line or just a turn.
;)

Thanks guys, i couldn't be any happier with the LS1 Swap, i should have done it years ago.



Killer numbers, Brady! Get out there and race....doubters will always be doubters until they get drug :)

Isn't that the truth. I will be checking in with you for those 1-7/8 headers soon. I didn't realize they were sold out already. You guys always have great products for a great price, so nothing sits on the shelf very long down there.

Can't wait to see some quarter mile times, should scoot for sure! If I still had my LT1 trans am, I definitely would've swapped an LS motor in it also.

Awesome numbers and I consider the higher compression ration to be the key in the above average numbers made from this combo, like pointed out earlier by roadtrip. There was a guy with a c6z on the corvetteforum that gained 30hp/30 tq through most of the power band just by milling his heads to achieve a 12:1 comp. ratio.

Compression makes up for displacement, which would lead to you being able to successfully run a bigger cam and in return a more usable power band with that cam.

so it does go fast in a straight line :)

Yes Sir, Now i cant wait till i load a couple kits( 100+75), at least till it pops. Everything is here but a stand alone fuel system.

Compression makes horsepower

474rwhp 422rwtq on pump

Compression is 12.0 I think

congrates on the car and numbers

but i find it rather funny after reading all this thread and how you got big headed about you know your shit with secret lil tricks your not gonna give away to other i know when it gets this big and bad boy of a build you go into figuring out the DCR/SCR other wise you wouldnt have it on race gas and have it full tuned and then to make a comment like about about compression

I do get a little big headed from time to time, hell i built the Fastest N/A LT1 in the country behind a t56, so i guess that means i can drive too. Then to top that accomplishment i jumped into the 500 Hp LS1 Club, on my first try, which is not that easy to do apparently.

I did figure the Static Compression and the Dynamic Compression Ratio's , thats kind of why i went to all the trouble of running the LG G5X3 cam on a Cam Doctor, and having my heads Flowed and CCed after being milled... OH SNAP.... I didn't mention that did one yet did I? The motor doesn't require race gas, it runs on pump. I put it on some sportbike MR12 fuel at $23.00 a gallon just for testing. VP claims a 11% increase over pump on motorcycles. I drive my 507hp street car to work and back, 250 miles a week on 91 octane.

When i did tell the actual timing guys felt the need to give advise. I have a hard time trying to take advice from someone that doesn't do there own tuning. I wasn't asking for advice i was simply stating this is what mine made for horsepower.

you only have a 500hp car when you decide to put $23 dollar a gallon race fuel in it

so in reality your driving a 475hp car on the street 250mile a week on 91 octane cause i dont think your gonna spend $ 250-300 a tank on gas to get to and from were ever your going and have the car on kill all the time

so again your big head ego has given out 2 stories from what i can see from your post



91 octane = 475'sh rwhp that you daily drive on 250 mile a week

MR21 race gas = 500+ rwhp that you flaunt and go racing on

so whats the story do you keep it on race gas 24/7 and have a 500 hp street car

or is it a 475'sh hp car 90% of the time when driving any given time on the streets of TX



once again props on the power levels made

Ok you got me.. It's 475hp in street mode, then when I get called out to race I load the MR12 and drag wheels along with the GoPro.

Lol let them haters hate

Very nice.

Damn it, cant see the vids at work... what did it run? It looks like one hell of a combo, congrats!

nice ride. runs hard. BUT GAWD! LOSE THE GAY ASS WANNA-BE MUSIC! put some good music in there! That kind of music makes me wanna smack people, NOT DRIVE FAST!:eek2: AC/DC shoot to thrill woulda been good there. or some pantera or something.
sorry for the rant. its just that you need loud fast screaming music with loud fast screaming cars and bikes. thump badump just dont go with sound of screamin engine
