Dyno'd my 403ci in my camaro last weekend on a dynojet in seekonk, ma. Buddy Mike V (back to back ltx n/a shootout champ) had been street tuning the car with me but havent tuned it on the dyno yet this was just a dyno day i ran. Still a little more on the table since we did 4 pulls and it kept making more power every pull. Car also needs a vacuum pimp frome crank case pressure.

Well built setup and the numbers back it up. Congrats!

 

Nice numbers, I hope mine puts down some power like that

 

Numbers look good through that S60

"1nastyss" your combo should produce similar results too. I wouldn't worry about it.

 

Looks like a beast set up. I want that looks exhaust, how do you like it ?

 

That setup is identical to my old 402. Same heads, cam, i even had the kooks td setup for a bit. Nice results.

 

Great numbers through a 4.10 geared S60! Gotta be a lot of fun on the street.

 

Nice numbers. I bet that car is a beast.

 

With tfs 235s prob be alot more these heads are very old i maybe getting a set ifbi dont turbo it this winter.

Love it nothing sounds like my car but it can b a bit loud but i have no cats n thatll prob tone it down a bit.

 

Get u in trouble pretty quick lol

 

Now looking at it, my eps cam that Geoff speced for me looks very similar to yours too

 

nice joe. whats this about a turbo setup? jeesh...
i might be interested in the heads in a few months but i would have to get rid of your old ones. what CC are they?
notice any improvements with the 102?

 

Need those 225s on my motor only changing the pistons to a-32cc

 

Congrats. You setup is almost identical to mine aswell. I run an LQ9 404 with the same 247/251 TR stroker cam with TFS 225's. Mine made 531/487. Do you have a dyno graph? I'm Interested in seeing where yours peaked compared to mine since we run the same cam. My 404 peaks abit early IMO (6300).

 

How hard was it to fit the Kook TDs to the ARH headers?

 

Barney mine peaked at about 63-6400 then started losing power i took a pic of the grah since i dont have a scanner.





Wasnt hard i cut the slip fit ends where it is a straight part n added about 3 inches to each side.

 

Rob here is you dyno graph's for comparison i have all three

1st is with the unported 102 set up when it was first built


2nd is with the my Ported 92 combo with more break in miles


3rd is the overlay of the 102 vs the Ported 92 combo


Tommy

 

good job...

 

I like the 102 vs 92 graph. Identical bottom and top end but a significant increase of mid range.
