Well I took my car to see what it made on the dyno the other day (monday) at a local shop..

First my mods are: longtubes, x-pipe, stock axle back, varram, slp underdrive and a ls7 clutch, cutouts... I do believe that is all..

My best was 430hp/415tq... Just thought I would share with the rest of you vette owners, I'll take a pic of the graph next time i run up to the shop... Numbers are uncorrected in 60 degree weather pretty much at sea level where i live on a good day.. I am very pleased to say the least..

BTW, it makes power all the way through 6500 rpm, I shift at 7000.. soon to be higher after a fast intake..

Oh, I also ran it at the track... With a bad master cylinder and not getting into 4th gear (letting out at 110, top of 3rd) letting out a considerable way before the traps...

1/4 E/T: 12.3
1/4 mph: 110
60' : 2.0




This pass was on a set of bridgestone potenza's with 18000 miles on them that have been sitting up for 10 months while my car didn't have an engine.. This resulted in immediate loss of traction after i left the prepped section of track and wheel hopping/spinning literally the entire way down the track...



I am EXTREMELY pleased to say the least..

 

I'd be very pleased with those dyno numbers, that's a big gain for those mods. Getting those kind of numbers without a cam or heads is very impressive.

 

Those numbers are very high, I would be really happy with those numbers but it should be into the 11s with ease.

 

I'd be pleased with those numbers as well, but there's absolutely no way they're accurate.

You'd be trapping well over 120mph in cool air, low altitude and with 430rwhp.

With the same mods AND a Ported FAST people aren't hitting close to those numbers...not even LS3's

You found a VERY friendly dyno.

 

This is at the wheels and SAE corrected numbers?

 

An ls2 with those mods isnt making 430 rwhp. Don't put to much faith in those numbers.

 

From my run the other night it should be a mid to low 11 second car at around 120 or so.. with the drag radials on and actually being able to shift into 4th.. And that sucks for other people i guess lol.. Heck even not getting into 4th if i cut a decent 60' it should be knocking on the 11 second door if not in the 11's at 110 which is pretty absurd..




Yes, at the wheels and no not sae just what it put down for the day... .like i said it was about 3 feet above sea level and a 60 degree day.. open cutouts..

Idk, I can see the dyno being off by a margin but for it to reach 430 and not be in the neighborhood of that the chance is a bit scarce.. Even if it's 10whp off it is still making pretty good power..

 

You simply aren't making 430rwhp with intake/exhaust and an underdrive pulley. You didn't find some magic combination that's giving you 40 more rwhp than anyone else. You're "making" the numbers that guys with moderately large cams make on the stock intake.

That would be gaining ~80-90rwhp from those mods.

What was your 1/8th mph/et?

 

No need to get butthurt over it.. but the dyno says what the dyno says..

I never said i found a majic combo but maybe a combo that works together well, and was well thought out to work well together instead of just buying random stuff and throwing it on my car.

My 8th mile et was idk and the mph was between 90 and 91.. I wouldn't count on those being too accurate though, due to spinning and my no shifting skills coupled with a dead master cylinder....

As stated before even if the dyno was off by 10 to 15 whp it would still be above the 400whp mark.. so im happy either way.

 

Thats more than an ls3 makes with those mods and a tune. Half the people on this forum with ls2's have those same mods and it doesnt make anywhere near 430rwhp. It makes somewhere around 390rwhp.

 

So i've got some sort of record?

 

I wasn't aware that I was getting or acting "butthurt" about anything. I'm just trying to help you understand that your car isn't making 430rwhp.

How do you assume you have a low-mid 11 second car if you didn't even get a decent run?

I'm also not sure why you're assuming the dyno numbers are only off 10-15 hp when the numbers are uncorrected to begin with. Dynoing in great weather alone, while being uncorrected, will skew your numbers horribly.

If you had your car dynod on a calibrated dyno, sae corrected, I'd expect it to make around 385-390rwhp and just a little over 400 after a ported FAST.

Are you expecting 450rwhp after the FAST?

 

Did i say i was expecting 450whp after a fast?

man some of you people on here get sooo butthurt... And i was using 10-15whp as an example.. Point was, at that moment on that dyno uncorrected on that particular day in that weather, my bolton c6 ls2 made in the ballpark of 430whp.. even if the dyno was off by up to 20hp it was still over 400whp..

 

The car doesnt make over 400rwhp. If you truly believe it does, then you have been hitting the "SpecialSause"!

 

Maybe it doesn't.... but the dyno said it did..... I can try to get the pic of the pull.. idk what to tell you...

 

It would be reasonable to assume you'd expect 450rwhp if you believe you currently have 430rwhp. 20rwhp for a Ported FAST is pretty standard.

I'm also not quite sure why "butthurt" is your go-to phrase or why you think anyone in this thread is "butthurt" over your exaggerated dyno numbers. We're just trying to educate you on what your cars setup would be making if you're interested in making comparisons to others on this forum.

You're still assuming the dyno is only off by 20rwhp uncorrected. I just hope you're not dissapointed when you hit the track and don't see 122-123mph trap speeds that a 430rwhp car should be producing.

You are correct in saying that on that dyno, on that day, uncorrected it made 430rwhp. I believe that 100%. Talking uncorrected numbers allows for no basis of comparison though. We're only trying to help you in understanding your car better when we say that going by the standard (SAE) your car will make around 385-395rwhp.

 

Whos dyno? EPS or Futural? or XXX?

 

sorry but no I'd find another dyno and see what it says....I'd bet 390ish

 

Did your factory LS2 go back into the car? You wrote that your car was without an engine for several months. This would clear up the speculations of your dyno numbers of a stock LS2 w/ bolt ons.

 

I can see why the OP thinks he's making 430 rwhp, as the weather it dynoed in would mean almost no correction factor (depending on pressure).

But, I agree, the dyno is off at least 40 rwhp (unless the OP slipped a cam in there and forgot to mention it).
