what is the typical output of a N/A 402 or 408 stroker motor

with decent sized cam( need suggestions that match heads), free-flowing heads( AFR 225 62cc), all bolt-ons, FAST intake, 90mm tb, lunati rotating assembly

going through a 60e and 10bolt

400rwhp, 450rwhp, 500rwhp, 550rwhp or more

wanting to see if i need a 80e and if not how much spray i can run on the flt level 5 65e

will never see forced induction

will be run NA 90% of the time with spray when i rarely go to the track

 

400rwhp is easy from a 6.0 with a godo setup 6.7 litre expect in the 500s. now you can have alot less if setup wrong. if i dont see between 500 and 550 rwhp ill be pissed

 

you should be in the 500s fwhp. I haven't got to see if i can break the flt5 yet with n2o but hopefully this comming spring i can try it

 

how much n20 are you spraying and is it dry, wet, or DP

 

when i get the chance it will be 150 shot and up from there.

 

If your gonna spray a 408, your gonna need a 4L80E. Your talking like 600+rwhp on a 100 shot with that combo you described.

 

Why are you asking all these questions now? You have said time and again its going to be like 4 years before you build this motor and by then EVERYTHING is goign to be different.

 

He can ask whatever questions he wants, just like you. If you don't like the questions, you can always just close the thread. Contribute or move on imo.

 

Anymore replies like this will result in a short vacation from the site. This is your warning. PM me if you want. Reply here and the vacation will start early.

Have a Merry Christmas.

 

I would think with a setup like you are talking about 500+FWHP would be cake. Check the dyno section on ls1tech for 408/A4 results. I know they have less drivetrain loss but it should give you an idea of what you could make with a 408. This guy made 470RWHP through an automatic
