For the low boost you will have to run, it would be better to run an Eaton.

Besides I called Whipple today and they said that there is not enough demand for them to start making the replacement for the 1200AX. No small displacement twin screw kits form Whipple.

 

Why would an Eaton be better? This isn't a prosecutorial line of questioning, I'm just curious as to why the Eaton would be a better than choice than a turbo. Yeah turbos take a sec to spool up, but they have 0 parasitic drain. As to the Whipple, no support, oh well.

 

not true.....we might not be able to run high boost levels....but the high compression means it would take us less boost to make the power equivalent of a 2.0 ss/sc.....besides hahn said he is running around 8 psi of boost making 240 whp on a stage 2 turbo.....

 

Well I was just addressing the S/C side of the question. If you like turbos better, then go ahead and get a turbo. I personally don't like all the extra room and the lag that they have. S/C is much more simplistic in my mind.

Between superchargers, the twin screw is the most efficient and has high boost abilities, but is also the most expensive. If you are not going to exceed 13psi then why waste the extra money on a twin screw when a roots will do the job for much less. That is why Whipple is not making the W75AX. There are not many small displacement s/c motors stock. Most small displacement FI motors are turbo and would be more difficult to swap from one type of FI to another.

I categorize 8psi as low boost. The Eatons are mostly efficient up to around 13 psi. You might be able to push higher levels, but high boost + high compresion = detonation. You would have to run race fuel which would not be that economical for a daily driver. But if you want to do it, more power to you. If I could afford it, I know I would.

 

what other mods did they have on that vehicle?
