Project Black Betty

Nice Progress....subscribed.

What turbo would I recommend for this engine?...hmmm

225ci x 6000max rpm / 3456 = 390.62 cfm assuming 100% VE

390.6 x .85 = 332 real world CFM NA

coverted to LBS/min = 22 lbs/min Naturally Aspirated at 85% VE.

To make 500hp/500ft/lbs....55-60lbs/min would be required...

So we want a turbo with a range of 25-70 lbs/min

hmmm

T3/T4, 1.06 Exhaust AR.......GT35R.

44mm wastegate

Water/Meth Injection above 12psi.....

should make 450ish at 10psi, pump gas

550 ish at 18psi

and be flowed out at 25psi...somewhere around 600ish

Garrett GT35R preferred, but knockoffs with comparable specs are much cheaper....
Heres a nice comparable
