My Cartek Heads and Cam Camaro just dynoed 443 Hp and 398 ftlbs.

That is with a 3X cam and 241 heads. (Who needs 243 castings)

No ported throttle body, no ported intake, no shortbelt, no tricks.

This was an NA pull for a car tuned for N20. (TR6 plugs, 1-7/8 headers etc.)

Here is the best part... the car has an automatic. a stock 4L60-E
and a Moser rear which takes more power to turn.
It even has the stock steel drive shaft.

I switched my Kooks headers Catted Y-pipe out for an off road pipe.

Julio tuned it and walla 443 HP.

If I go LSX and 90mm TB I am sure to break 450 if not 460 RWHP NA. Add in an aluminum driveshaft and a short belt and watch out.

Can you tell I'm happy?

Dave I hate to admit it but you were right again.

Thanks to Julio, Dave, Roy and Rich. The car was in, parts changed, Dynoed and out all in the same day. Pollen didn't even get a chance to fall on it.

nice #s. not often you see an automatic lay down those numbers.

Thanks, my thoughts exactly.
I would like to break the 450 barrier. So close yet so far....

Time for more mods I guess?

I Went 10.80's@124 threw an A4
S1 LS6 heads ported locally with a TR224 and all the boltons...
I never had it on a dyno but I bet it was a bout 430RW...

I bet with traction u have a 10 Sec car...
Impressive numbers Anon......

Thanks again.

Yeah 10.80's is no joke. 430 sounds right.

I would like to get in the 10's NA, but I don't know.

I have a lot of compromises in my set up for the N2O.

Converter, gearing, header diameter, spark plugs etc...

That is why I am so surprised by the dyno #'s. I didn't expect it to respond as well as it did. But we race cars not dyno's. We shall see.
All things being equal whether the number are a little high or a little low, they have to be in the ball park. The weather outside was average so I figure on a hot day 425hp, in the winter at Atco 460hp. Even compared to other Cartek cars I am making great power so I am using that as a barometer.
As opposed to other dyno's that I have no experience with.

If I can upset some six speed Cartek customers something must be right!

Great numbers. Was the convertor locked?

Yes the converter was locked. It is a Vig. 3800.

I have a deep pan and a trans cooler.

Yes, this is on an LS1 with 241 castings (which are LS1 castings not ZO6)

No, stripper HT cars came with steel drivshafts.

Dude your car rocks you don't need any more mods.

I wish my car was half as nice as yours.

You must have a nine in that car on the bottle.

Cartek does it again.

awesome #'s, what were the numbers before swapping to the ORY? I'd like to know the power gains from switching from cats to no cats...

Anonymous

Thanks

I knew someone would ask so here you go...

w/Cats 432.1 Rwhp & 384.6 Rwtq
OR Pipe 442.9 Rwhp & 398.0 Rwtq

Basically 11 hp & 13 tq gain.

Both with converter locked.

Nice gains in my opinion. They were high flow cats as well.
Whatever comes on the Kooks Y pipe for $500.00
I think they are Magnaflow, but I am not sure?

What catback, or did you dyno through a cutout? Great numbers, btw!

It was through a Corsa Cat Back. I gotta tell you. I know they are a little more expensive than most and maybe a little heavier than some (because of the high quality materials) but, They sound great and there is no resonance and to me that means a lot. I have the one for the Camaro only, the twin 4" tips (one on each side).

I also have a few friends who have Corsa and all are happy.

I called Corsa before I bought that cat back and they said it was not restrictive up to 600 HP. So, I am not worried about it at this point.
I figure at the most I am making 525 to 530 at the crank.

BTW AWSOME NUMBERS.
Through a A4 with a stall that is damn impressive.
Big congs.
I can see low 11's on slicks maybe even a 10 with that stall.

Sorry no I don't. But the idle was worth the money of the heads and cam alone! It sounds sooooo mean.
When other guys hear my car they just look at me and grin.
They know there is trouble lurking under the hood.

Vig. 3800 Multi Disc.

The stall is a little tight NA, but on the squeeze it should be perfect!

Thanks.

The 3800 stalls to around 4400. It will be too loose for Nitrous. You need a Vig 3200 which stalls to 3800 for the juice.
