Actually with the orginal data you posted 439rwhp you should be trapping 121mph in the 1/4 i've seen MANY cam only cars with boltons trap 118+ with stock heads..


Stock i ran a 13.2@106mph in a 98 Z 6spd..

elcheapo

Excellent. at 3800. I can assure you you won't see any full weight TA's trapping "118mph+" with a 224 cam and stock heads. BTW It was 429rwhp.

Not that I consider these accurate, but it's funny how it is accurate for me. http://www.speedworldmotorplex.com/calc.htm put in vehicle weight of 3750 (incl driver and gas) and my best trap of 114mph, i get 434rwhp...
Time for some weight reduction

Jason98Zee

Its funny that everytime you post theres a different side to the story.. you said that theres no way you'd be trapping a 118+mph but you also said that you were alot slower at 114mph than you'd thought youd be with 429rwhp.. then i say i have seen many cam only cars trapping 118+ then you tell us about your evelvation.. tell someone the whole story in the first post and that way you can expect right results instead of telling everyone they are wrong because of faulty information

elcheapo

oh, this is frustrating.

I can see how youd be mistaken the way i wrote that in. I'm not high eleveation. 3800 is my raceweight. I'm not adding any new info in. Full weight, stock gears 429rwhp my best trap is 114mph. A little dissapointing yes, but you said you've seen many cam only cars trapping at 118mph+, I just said you wouldn't find one at stock weight with the same cam as me, all i wanted to do is prove you wrong when you said "you should be trapping 121mph with that HP" i think that's untrue for my weight, and setup. maybe a few mph off but certainly not 7mph.

Llyod Elliot did the heads on my car, no dyno's with recent setup but I made 395rwhp/384rwtq with only 25degrees of timing through a PY3600E and on a trans that took a dump two weeks later.

my previous best on a different tune was 396rwhp/394rwtq with 28 degrees of timing running rich

You can see my site for more info, no new dyno's on new setup with 30 degrees of timing now

i know of a cam only T/A on here with only a few weight reduction mods. such as spare tire is gone, battery from front to back, no back seats. but he also has SFC's, LCA,s he's got full exhaust and he went 11.93@119

elcheapo

and what were the specs on that cam? 231+ duration? .595+ lift? I thought so. I'm not debating that there are way faster cam only cars or that its not possible. My car is practically completely stock other than the engine mods. No suspension or drivetrain. The car your talking about has suspension mods, weight reduction, gears ect ect. Anyways, no doubt my track times look bad when compared to my horsepower, I just didn't agree when people automatically assume it's my driving. I'm probably just your average driver, I ran 13.3 stock.

Jason98Zee

Well yes the weight reduction pretty much evens out.. he had full exhaust which the headers and the extra weight of the magnaflow probably is heavier than stock.. removing the spare tire and battery is offset by the wiight of the SFC's, so when you really think about it theres not much reduction. and if you want track times why dont you worry about putting what power you had before to the ground before you do mods to the engine? i mean hell.. a stock LS1 has more power than it is capable of putting to the ground.. get some good sticky tires and some SFC's and you got a 12.8 12.9 car.. add some LT's and your 12.6 area around 110? then do some gears and add a cam or LS6 intake etc etc..

Im sure 4.10's would help u alot because i had the same problem with my car. I trapped 114mph with 392rwhp and a full weight of 3700lbs and stock gear where i shift to 4th gear at the last 60-100ft. I guess thats why i trapped low for the power my car is making. When did u shift to 4th gear?

elcheapo

EXACTLY what happens to me. I am forced to shift to 4th and barely get my foot back to the floor. I am in need of gears.

elcheapo

Your right I'm really not too worried about track times, this is a street car 99.9% of the time.

A buddy of mine that posts on here has a 02 WS6 with the TR224 .561 114lsa and long tubes and a pulley. he still has cats and dynoed 380rwhp and I want to say around 360rwtq. car is full weight and with the 3.42's he trapped 115.7 just to give you an idea on a 2.3 60'

sorry, i have to call total BS on a MD @ 429rwhp with those mods. If that 429rwhp was 'calculated' from the MD numbers, what were those?

No those are the honest numbers that came up right from the dyno no calculations. I still think there is somthing wrong with the numbers somewhere. Anyways, here is the page with the dyno info, he says his dyno is a bit different than other mustang dynos http://wallsrodcustom.com/services_d...52717c460932fa
anyways even if i'm making ~420whp I'm still trapping lower than i should be even with stock weight and gearing. Trust me I'm not that horrid of a driver. Maybe i should just disregard the dyno numbers, and finish the bolt-ons. And like i said these heads from Loyd aren't anything special, they were the cheapest heads he does. The only reason i have them was because I got them at almost the same price as the core charge at some places.

tump

If those numbers are correct then im going to be sick......But great for you, It just makes me feel like a fool.

My car is full weight(3720) with me in it.I have a split duration 224-228. My car dynoed 426RWHP and 406RWTQ and that was with a 12bolt rear with 4.11 gears and a denny's nitrous ready steel driveshaft. Your #'s seem to be way off.My car with the stock clutch launchiing soft I ran a 11.5 at 119 with a slick. If I had a drag radial on my trap speed would go up but my et wouldn't be as quick but still in the 11's. My car before the heads and cam went 12.2 at 109 with alot of bolt on's and 4.11 gears.If your car was really making 429rwhp you would at least be running a 11.9 I was running 12.2 before I ever got in the engine with the stock factory tune and cat back.To anyone listening, if you do every bolt on there is out there and go with a x-pipe to 3" true duals and get your computer reprogramed with LS1 edit by someone who knows what there doing you can get your car in the high 11's with out getting into the engine.I know the tune and x-pipe to 3" would have been worth more than 2 tenths.Sorry to get off the subject, get your car re-dynoed on a dyno-jet. Somethings not right
