with the last bracing that Derek's car had - that you bought, do you remember what the limits he found were with that setup before a belt would break?

 

I PMed him and asked . waiting for a reply

all's im wanting is to get to redlne...6800 to 7200rpm
my whole intent was to find a pulley system that didnt need to be tight as hell , boost to redline , and so the stock pulleys[ bearings ] for ac and alt. wouldnt get wore out

 

I really am not sure why the belts breaking is such an issue on this car. I mean, the lotus exige S revs to 8500 rpms with a supercharger.

I guess it has more to do with running a lot of boost AND reving high. Though you'd wonder how the top fuel cars pull it off

 

talking about top fuel SC's ...lol . a stock hemi motor [ say 400hp ] couldnt even turn the blower on a top fuel car . thats how tight that blower is

 

I run 9 Psi with no belt issues ever(ATI).... I usually never take it to 7000 rpms though. My peak gain is at 6250.. somewhere around there.... I think the highest the ATI can go is about 12 psi before people were having problems..

 

I think that 500whp is not unobtainable with a stock compression built motor 2with some 93 octane and some water/methonal injection.

 

That is with the right belt setup at least. Using any of the stock configurations for pullies I think it would be a struggle. Cog setup is one way and not unachieveble or a 10-rib would be a good solution if someone were to make one... in the near future.... cough cough
