I have the Hellraiser kit for my cobra with the stock eaton. Just wonderin if upgradin the blower to a KB er Whipple would be more efficient or even make easier power. Twin screw vs. stock i guess is my question. Thanks in advance.
The TS would be less of a restriction at higher boost levels, but it will also be a few thousand dollars more money too. I personally don't like the idea of the whole compound boost thing. The turbos alone will make more peak HP. Just my 2 cents...
some people aren't after peak numbers. there is a reason for the compound setup. but I would say it isn't for everyone and isn't cheap because you should plan on a built motor immediately and need to invest money in it to handle the boost levels of compound setups.
peak numbers look good at dyno days.
X1000 and speed looks good on track days
