Who here has HF twin turbos and what kind of power do you get now over the stck turbos? I know one member, I believe captbill1 just pu tin M2 BB twins but hasen't dynoed yet. So was wondering what you guys with HF twins though about them, and what kind of WHP you get.

thanks Gun

 

ive had mine for 900 miles... and they need to rebuilt for a 3rd time.. The bearings just cant take high boost/usage levels... Im probbaly going single in the future..

 

Curious to know what is happening with all of the problems you are having.

I am at the stage where I don't know if I want upgraded twins or a single.


Gun -

I have been looking into upgraded twins...there is a very recent thread that has some info on the M2 twins.

Not too sure how to link another thread...if the above doesn't work just go back to October 4th posting date and look for capt. bill1 's post "M2 Twin..."

 

i thought u were only runnin them@ 10 psi? 900 miles and be rebuilt the 3rd time??? hope thay had a warenty

 

I'm planning on modifying a spare set of stock twins that I have to take T04B T5/6 compressor wheels. They are significantly larger than the stock wheels. Ofcourse I will also try to use larger shafts. The compressor housings would need to be opened up to accept the larger wheels. Anywho, I'm just experimenting.

 

Ive done a bit more with a fcc temperaty hooked up... They did well but they now have somemajor side to side wobble..
