404 stroker fully forged and apr everything
f1c-94 with aster bracket and race intercooler.
Meth dual injection
heads patriot stage 2.5
cam brutespeed blower cam
1 7/8 Texas speed heads
102 fast intake ported
nasty nate fuel system and tank
fuel pump 4301
injectors 80
tr6060
moser rearend.
car has every part you can buy long story short.
when and if I replace the injectors to 2000’s for E85 what HP will I gain?
car dynoed at 919 rwhp on new eddy current dynojet. This was at 18-19 psi. this of course was done with a 7.63 crank pulley and a 4.00 blower. Yes I get somebelt slip that’s why I and upgrading to a 8.65 cbr and a 4.50 blower pulley. It yields the same rpms.

Car makes 933 on e. Like I said it not tuned on kill. You can get more than 50 easily but considering the minimal timing in it it’s pretty good. It’s well worth it IMO. Only 16* on e.

I run a 4301 pump myself on E70 which requires less than E85 and it's not going to get you any where near 900 rwhp on E85. You need 2 of them or maybe a 4303 will get you there.
ETA: I gained 3 mph in the 1/8th mile by adding one more pound of boost and switching to E70. I only added 2 more degrees of peak timing to do it.
