it cant be a d15b7 then.. isnt that kind of a lot of boost for that much power ?

Heh. Eagle will custom-manufacture parts upon request... just like any other piston/rod manufacturer. And... Holy crap, ~280HP on a D15B7!!!

I just did a D16Y7 last week that made 265@ 20PSI on a SC61.. It had Eagle rods, SRP pistons, and everything else stock. I'll post the dyno later.. Be a cool comparison.

Def post it up

This car/driver went 12.15 with this car and his old setup (just barely 200 whp) so I cant wait to see what he does with this

here is my old setup. d16z6 vitara/tt rods, ebay t3 super 60@20psi. dynojet dyno. fast2camciv tuned.

car went 12.2-12.3's all day trapping 112-113mph with 282whp on 18psi. never got a clean run after getting it dyno tuned.

What are the compressio ratio's of these engine's? I heard vitara pistons gives very low CR's

Posted: **Thu Dec 20, 2007 5:48 pm**

the *NEW* -15.3cc gives a compression of 7.45:1 with the z6 head and 7.11:1 with the y7 head if everything in the calculator is correct. im not sure about y7's combustion chamber volume. some say its same as the z6(34.6cc) others say same as the y8(32.8cc) which i doubt. this compression calculator says it the same as the a6/b7(38cc).

Sorry it came out huge..

I did a Y8T with a peakboost kit on it that made 310ish on 20something pounds with a 50trim t3t04e. I'm having some issues with vtec transition on the street (was perfect on the dyno? go figure). I'll try to post up the graph in the new years after I get back there.

Posted: **Sun Dec 30, 2007 1:22 pm**
