How much HP do you guess the following combo would make (12valve)?

-Modified HX35 with 18 or 21cm exhaust housing
-Ported Head
-Helix 2 Camshaft
-Properly tuned pump

Im gonna guess you could make around 450 with that combo. Im just curious to see how much power could be made on a "stock appearing" turbo.

 

I think taht turbo would still get toasty but maybe 450.

 

Some delivery valves would prob help out a bunch.

 

18-21 housing... It wouldnt get too hot... Well, maby a little...
450 would be pushing it imo...

 

By modified do you mean a hybrid with a bigger compressor wheel.

 

Yes. Reason why im asking is im just curious as to how competitive a 12valve truck could be in the Work Stock class in DHRA. To be competitive in this class you're better off with either a Dmax, or a 3rd Generation Cummins. The current DHRA rules limit the trucks to "stock appearing" turbos, but you are allowed to interchange different turbos from different years as long as it is the same manufacturer of truck (example: you could put a stock turbo off of a 93 1st gen on to a 97 2nd gen). What is done on the inside of the turbo really doesnt matter, as long as it appears to be a stock turbo from the outside.
