If your goals are set that high at 5.50s, i would highly recommend talking to the guys at Comp turbo. They have very efficient billet wheel design that will meet any needs you may have. even if you are set on that little 4.8L

And if the 61's are good to 900 flywheel there is no way they will make 900 to the tires thru a 9" and th400 lol. I think the 67's woukd have been a slightly better choice but I think these 70's will do perfectly for what I want to do.

BTW those On Three 60s sound just like a SC61, or p-trim(64mm) with a 61 mm compressor. And those were generally done making power at low 600s hp. each. usually only getting there with a high PR(=small engine)

By looking at a compressor map...they show air flow(HP) by pressure ratio(boost) to give you an efficiency number or surge limit. No where do they look at an engine size. It could be guessed by the HP it makes at lower PR, but that would be how you calculate AVAILABLE hp(mass flow) by a specific boost level. A compressor map, if available.

Ran them before, zero issues. Tons of low 8, high7 sec cars running them on YB. No point in spending 500 on something that does the exact same thing

A few big changes made, decided to ditch the stock ecu and go with the Holley HP. I think it will be the best investment I make.
Also decided to use the two 70mm turbos and keep it simple with a single so I ordered up a s475 just to get the car rolling and will probably look intova 76R when I max this one out. I saw that new x235 class rules come out and it looks pretty interesting and is limited to a cast 76mm so I hope it will lead to slower 5.3x-5.5x class.

Yea primarily an 1/8 car.. I like 1/8 racing and I think the motor will be capable of more power only running 1/8
If your building one, you might like my last build
