ok guys took me a few weeks to finally get out to the track. unfortunately its on an 1/8 mile track, no real close 1/4 miles around. like i said it only dynoed 411 rwhp and 385 wrtq.

First few runs really sucked, i had to find the right launch rpm. about my forth run i launched at 3000 rpm. got a 2.05 60 foot, and ran 8.07 at 91.02 mph. i ran it one more time. launched same rpm got a 1.92 60 foot and ran 8.0009 at 85. well sucks i missed 3rd gear so i just cruised across the finish line. i was thinking it should run high 7's. with a little more practice and better tires i should be able to hit it pretty easy.

so now my question is are my dyno numbers pretty accurate to the times i was running.

You can't control your driving skills, but your MPH will give you a good estimate.

 

I never get tired of posting this. You are giving up a solid 15/15 at minimum running an LS6 intake. Headers could be better as well but the main area of concern is the intake. What is the setup before the air bridge? And get that LS6 off asap and put a FAST on

 

Guys, you crack me up. Why spend $1000+ on FAST and go cheap on heads when if you had put that money towards better heads, the LS6 intake is plenty to get mid 450rwhp numbers on M6.
Yes a FAST will enhance the setup a bit further but LS6 intake is not crap. Trick is to match parts to work together properly, and real good heads are the HEART of any motor making power.
When are you guys going to wake up and understand that buying any part that advertise it will make XXX hp is just marketing gimmick.

 

Well I have a set of good kooks headers on the way now. And I'm keeping an eye out for a used fast. Don't want to spend the money on a new one

 

EXACTLY

also i would try a different tuner. The key to your car running at its best is in the tunning. You already have a great set up from what it sounds like. Just my .02 cents

 

IMO, your 60' sucks and I would work at better weight transfer/ hooking first to get the 60' down to 1.5>1.6 range
(If drag racing is your thing).
Also see how you can loose some weight on that car.

 

Most cam only f-bodys run 91 mph in the 1/8th. A vette (lighter) with H/C should be running mid-high 90s IMO. Something is seriously wrong with this combo. The roll race with the stock Camaro proves what you already knew.

 

I agree there^. I would recheck the tune and then go from there...

 

I don't think you are going to jump to 430-450rwhp off adding kooks LT's. With that set-up you should be in that vicinity based on the average of what most have. I would have the tuned checked, then start doubling checking other things.

 

Another thing to look at is what was your baseline number and what did you pick up. Most heads and cam packages are good for an additional 80-100 hp over just bolt ons.

 

Curious if you're running the stock axleback exhaust/mufflers?

Anyways I have a set-up very similar to yours on my '00 M6 Vette: PRC 2.5 5.3 heads (62cc chambers), Torquer V3, 85mm maf, LS6 intake, 42lb injectors, 225lph pump, TSP longtubes, 3" ORX, Z06 Ti axleback, LS7 clutch. I put down 430whp / 400wtq on a Dynojet. Before that I dyno'd 400whp / 383wtq on a Dynojet (but at a different shop with different tuner) with the stock 75mm maf and stock C5 axleback. So I'm not sure if your dyno numbers are too far off.

As far as you not pulling hard from your friend in the stock 2000 Camaro, there is something very wrong with that. My Vette pulls so hard from a near stock F-body that I can't even really tell they're accelerating, seriously. I recently ran an LS1 M6 Trans Am with headers and exhaust from a 60mph roll and I pulled so hard it was ridiculous. A couple weeks ago I raced a friend's automatic '04 GTO with a Magnecharger at 5psi, long tubes, full exhaust, LS6 243 heads and dyno tuned. I pulled on that GTO pretty good from a 55mph roll, about 4 car lengths to 140.

 

I think you need to spend some money on drag radials and a lot more time at the track. I'd be willing to bet there is a few MPH difference in figuring out how to get the thing out of the hole and when and how to shift it. Even if you do find another 20 hp, without more track experience your still most likely not be any faster...

 

well i never dynoed the car when it was stock, so i dont have a starting point. i also didnt build an all out race/drag car, it was only to be a fun street/show car.

As far as racing my buddies stock camaro, i ran him at the track. Its an 1/8 mile track and i put about 2.5-3 car lenghts on him almost every run. (4 runs in all) when my car was stock we pretty much ran side by side. so i know that its making some power now.

As far a new tuner, the place i took it to is called HHP Carolina, their suppose to be a pretty reputable tuner here in the carolina's. i know there's better ones out there but i dont have the time to take it very far.

Ill also admit im not the best driver when it comes to launching. a 1.9 was pretty damn good for me haha. I only get out to the track maybe 2 times a year.

 

Sounds like while their might be a little more power in the intake bridge and exhaust and maybe the tune (less likely IMO), your driving is also hiding some power.

I often see manual trans cars run slower in the 1/8th than they should MPH wise but trap normal in the 1/4.

411rwhp isn't that far off in the first place. if you told me your setup I would have guessed 425-430rwhp. Not every ls1 is going to put down 360rwhp with bolt ons, 415rwhp with cam, and 450+rwhp with ported GM heads...it takes a good combo with all supporting work. Look at how many donkey dick cam owners are on this site making 390rwhp or less with a manual trans....

 

I saw a h/c ls2 only put down 420 if that makes you feel better.

 

Totally agree! The first 200 feet (especially first 60ft) is critical in 1/8th mile. You can make alot up on the big end 1/4 that your lacking in the 1/8th.

What kind of tires were you on?

 

like i said im not the best driver, so im pretty happy with what the car did at the track. And its still screams down the street. faster then just about any car around my area.

at the track a good driver mod might help though lol

 

If it makes you feel better, I did a 1st, 4th OH **** 2nd shift one time lol

If you can and your tuners let's you, post a few log and tune files....if your running hptuners

 

Something to compair too, I just installed my cam kit, springs, chain, oil pumps everything in my sign, I have gutted cats, the 01 vette already has the ls6 intake 85mm MAF, twin cone filters and a big carbon fiber air bridge smooth coupler and Shorty headers.
Waiting for my dyno sheet to pop up in my email. Just dyno tuned sat. My injectors are to small, so timing is down, had to set the rev limiter at 6100 instead of 6800, I'm "detuned", I still got 398 rwhp. Car is still very fast though. With my new injectors, easily another 25rwhp. Im also going to port my tbody. My cam is 230/240 duration 630 lift 113lsa. I have a very good tuner. Maybe there's more left in your tune
My car is a 6 speed stage 2 clutch 3:45 gears
