I made 420 dynojet with the same mods

 

What they said

 

415 on DynoJet.

 

That's more than I thought I would be hitting. Is that WHP?? Anyone know what gains I would get from running an E85 tune??

 

Should I get head studs put in at this HP????

 

^I wouldve put head studs in awhile ago just for peace od mind?

 

I was debating it, I heard the 4g63 is safe till 500whp before you need head studs.

 

I've seen FP red numbers with similar mods range from 410-460whp dynojet. I'd imagine with the new FP manifold you might pick up 10-20 more.

I wouldn't do headstuds unless you are going to put a new gasket on at the same time. There is something about the magic when the factory screws all of them in at once. The replacing one at time is questionable to me.

 

I made about 480 on e85 and that was on stock studs... i dont trust 1x1 method

 

Was that on a Dynojet or Mustang dyno ?

 

I don't think I'm going to go with an after market manifold yet or the head studs at all. If i make it over 400WHP with this set up I might think about going to E85 and see what numbers I can make from that. What would I need to run E85 with this set up??? All I can think of is a Cobb access port and bigger injectors??

 

Also It will be tuned on a Mustang Dyno at STM Performance.

 

420whp on a DynoJet is going to be closer to 370whp on our dyno (plus or minus).
The good news is you'll definitely be getting all you can out of your tune and it's going to drive mint...

P.S. You know, you could've just asked yesterday when you called!

 

I can see your red with some good boost / 93 oct approaching 380-400 WHP on the mustang dyno and don't forget those gsc s2 cams are going to help also.

 

Wasn't thinking about it at the time lol. Figured I could get some good feedback on here!
