I cant decide between the 55mm or 62mm turbos you can choose from with the Hellion kit. Can you guys help me decide? Heres some details about my car:

Auto with 3.15 gears. Will be on drag radials. The car is mainly a street car that won't see much track or drag time.

I want to trap around 140-145mph in the 1/4 mile on E85. Seems like that would be around 800whp?

It seems like the 55mm turbos they use have much better low end power without sacrificing top end power. With my goals in mind, they seem to be ideal but I don't want to fall short on my goal.

What do you guys think?

If you plan on Staying 850 or below rwhp the 55s really are pretty nasty we've had great luck with those were customers if you want that 4 digit mark I go for the 62

Let me know if we can help

I made mid 900's through the auto with the 55's(19psi) and alluminator .Trapped 147 @16 psi .

1100 with same 55's and 5.2 block/GT 350 heads .
Never got to run it since blew head gaskets in April(long story ).

18 psi and boost controller was at 70 duty cycle so may be the turbo's still had a little left ?

Sounds like you had a badass setup!

What do you think this kit would trap with my setup on 13-14 psi on e85 on stock motor? 140+ mph?
