I absolutely love your setup and I understand your initial reaction to the numbers.

I went in a very similar direction with my build and when I first heard the numbers I was a bit disappointed. Then I drove the car home and quickly changed my mind. It's nice to make power all throughout the curve in a package with good street manners!

You did a great job assembling a very complimentary setup. I think you'll be pleased with the track performance!

With the amount of torque you have and the shape of the curve...F*** the number, that car is gonna hurt some dyno queen feelings on the street and track if you can drive. GREAT build.

Makes me wonder what my 226/230 and TEA 5.3 heads will make. I'm using a ported LS6 intake and TB though

I would be interested in seeing. The FAST 92/92 setup might not have been worth it on my setup. I have several threads with people using LS6 intakes that make great power.

Thanks for all the kind words from everyone. I appreciate it.

about 370ft.lbs at 3000rpm.pretty stout combo bro,you don't see that too often with a modded 346,even with a mild cam.i bet it will run like a beast at the track.

Going to Mike's on 5/9, so we'll see. What % were your injectors at?

LilJayV10

iTrader: (39)

85-89% I think. I know it was right under 90.

That car has to be a blast to drive. I would take the power under the curve and that torque any day. No need to be disappointed.

The FAST 92 is def worth it on your set up. Especially with the heads. I would bet you gained at least 15-18rwh and roughly the same torque wise with it over the LS6. My Fast 92 on stock 241 heads put out 14rwh and 16rwt over the LS6. Plus my cam is just a hair smaller then yours too. HP/TRQ gains per the dollar spent are well worth it in the end.

Your torque curve is identical to mine until 5000 rpm. I really believe you have a valvetrain issue or a restriction in your setup. Your torque drops hard after 5000 rpm and you should be around 445-450 rwhp based on the math of torque and rpm if it didn't drop hard. Did you measure your push rod length? I use 7.350" rods with .020" milled heads. I also used the same headers and exhaust setup as you, except I had a 3.5" cutout.

It's a great setup and when you figure out whats going on it will make quite a bit more power. Did you look at the KPA drop as you went up in RPM? I'm not hating or bashing at all, I know there is more left in it. Here is my graph for example, and like I said almost identical torque curve until 5000 rpm.

No worries Nitroused383. I tried and tried to measure pushrod length and came up with 7.350. My heads have been milled about .025. It was super noisey, I mean really bad and I talked to Geoff at EPS about it. He reccomends 7.425 pushrods with that cam on a stock engine. Since I had about .025 milled off I went with 7.4's. I'm not saying that's right that's just what I did.

I appreciate the input. If something's not right I'd love to find what it is.

I think OP has one of best HP/TQ under the curve I've seen in a long time in a stock CI LS1. Very nice combo, congrats.


...Nitroused383, we see you all over the dyno threads with your 444rwhp with the BRE224. Your setup is nice and your numbers too, but you gotta remember that dyno are tuning tools and they are not all the same. I just wanna make a refresh for you on that. FYI, my car has almost the same duration(TR22x), unfriendly 3:42 gear, and my car did trap 117mph in the 1/4 with the same raceweight as you(no spinning,HUGE gear lag). Funny thing, it is with a crappy 2.2 60 feet, and I'm down 40rwhp/30rwtq on you. Not hating, not jealous, I read your thread and you know your ****, but you gotta get over dyno numbers sometimes.

Even me, I was thinking his car was down on power. Hes running 10.46@129mph... with 427rwhp... might be apple to orange because hes got a heavy drivetrain/auto, but still 20rwhp less than you and running wayyyyyyy faster than you, and me of course

I say your results are right where they should be... that's going to be a fun setup for sure. Don't forget that you are running a 226/230 afterall... that's great power without sacrificing a smooth idle. Geoff told me the same thing, 7.425" with stock heads, 7.400" if you are milling 0.025 or running LS7 lifters... which makes me wonder if you are running LS7 lifters? that would put your pushrods at too short....

I just started up my EPS 230/238 112+2 LSA cam 2 nights ago with stage TSP 2.5 5.3L heads. I am very excited to see that EPS cams make good power through 5.3L heads I was a bit weary of straying away from 243 casting heads. I'll have my results up soon...

Using stock lifters. They have 48,xxx miles on them.

The TQ is nice but the HP figures are definitely low for the mods. Most of my cam only cars do 415-425 with a stock LS6 intake and unported castings.

Replied to your PM.

Thanks for the reply Damian. If the monsoons quit this weekend I will take it to the track Saturday. I'm having clutch issues at the moment as it won't shift at higher RPM's.

Maybe the track times will make me feel better.

GoFastKid

Nice combo. As others have mentioned though, I would say you have another 15-25 hp waiting to emurge somewhere.

LilJayV10

iTrader: (39)

I have no idea where it would be. It shouldn't be the intake tract. I can't see it being the exhaust. It's either the cam or the heads.

I figured if it was a valve train issue it would show up on the graph but maybe that's not the case.

Turk,

Where did your power peak at? I couldn't find a pic of your dyno graph?

Nitroused383

iTrader: (10)

I was using my car as an example and I was trying to help the guy out as I know there is more in it. Fast / LS6 style intakes generally determine peaks and rpm range. His setup is dropping fast past 5000 rpm and this is something that can be fixed. You are also leaving out details when you do an apples to apples comparison as I raced at 2300' elevation in 4000' DA weather. I typically see 91-94 KPA at WOT, which is a big difference compared to someone at sea level in cooler weather.

No doubt you ran 117 mph but what was the density altitude you ran at? Based on the correction factors on drag times website for 0 DA' I could trap around 122-124 mph. Now I know alot of tracks back east see up to -1500 DA where people run their best. It's no secret what cool air and sea level tracks can do for an N/A motor. 125 + mph would not be out of the question for 3700lb raceweight.

Sorry to pollute your thread Jay. I had to bring all the facts to the table when someone wants to try and make a comparison. Oh and I'm not even going to argue about stalled auto dyno numbers and track times.
