Well I just finished installing a bunch of stuff. 4" MegaMaf pipe, Gen 2 Trans, New built Tranny, Art Carr NLU 3200 converter, & a BB CPT66 turbo.
My previous setup was a 6152 PTE journal bearing turbo, stock 200r4, pats 3200 lockup converter, POS intake and stock maf.
Now I am running both turbos off the wastegate at 12 psi, The CPT 66 seems to goto about 10-11 and hold. (I thought I would have a problem running 12psi with this turbo and a non ported WG hole?)
So with the 6152 it took till about 3200 to spool and when it hit 12 psi it felt like a rocket and would spin the tires loose at 60-70kph
The CPT66 spools very quick 2200 full psi by 3000 (12psi) but by 4500 it feels like it falls on its butt. It does not spin the tires loose at 60-70kph anymore and honestly feels like a, if lucky a high 13 second car where as with the 6152 I would have said the butt dyno said mid to low 13's. Both turbo's are .63 ar's hot
Any suggestions with this to get some top end back out of the car? Or is it just a matter of turning up the boost for the 66 to be more effiecent?
All my other mods are mostly in my sig.
I am guessing that the turbo isn't working well at low psi or the converter is slipping.
Any suggestions would be great.
Brandon!
