375ish WHP GTP gen 3

Im wondering how do-able that would be on a gen 3.

Current mods:
L26 bottom end
Custom cam
Ported gen 3
42.5# injectors
Slp headers
currently on a 3.4 pulley.

I know im no where near 375 now but ill be adding some stuff in the near future, like
n* with LQ4
Bullyflo heads ported to suit the custom cam
60-80# injectors
E85
300lph fuel pump
2.8-3.1 pulley
50-75 wet shot of nitrous
and supporting mods

Id like to think id be close to those figures. What do you guys think?
 


Youll be in the ball park depending on how the tune looks. Btw, you can reach 11.xx with those kind of numbers. Im in the 12's now and I have stock cam, heads and pretty much a stock tranny (that hates me) and I did it on a 3.0. Im rocking a 2.8 now with no issues really either. Just play with that e85 when you you convert and see what your car likes. Mine seemed to like boost more than timing honestly but some have better success throwing timing at it and leaving the boost a little lower.
 
Cmon now are you talking 375 whp including the 50-75 shot? If so I think you will be close. 375whp with out spray I doubt it. Even on E85.

For a little bit of perspective my setup is 330whp/400wtq on. S1X cam, gen5, tog headers, stock heads, 2.8 pulley, 60# injectors, FP rewire, 255 pump, and stock TB.

I highly doubt ported heads would pick up 45whp considering Im already spinning a baby 2.8 pulley. Spinning an even smaller pulley would be needed to take advantage of the ported heads. IMO.

I think at this point for you it would be money well spent to go to a gen5 also they are pretty damn cheap now and considering your swinging for 350whp plus I'd certainly try get one.

IIRC the max effort SC build Zach did that was previously in my caged car went 10.8 @ 126 in a stupid light car and made something like 420whp.
(XPZ cam, ported heads, IC, Gen5, E85 no idea what else was all done to that build.)
