Ok...everything is ordered. Got the rollmaster from Texas speed for $104.00 shipped.
What do you think about this...
Got the cam,springs and titanium retainers for $619.00

 

Called whipple to answer my question about spinning the whipple to 7k rpms. It will still make the desired boost at those rpms, but the life of the blower is questionable. I can only assume that heat would cause more wear and tear, and additional stress on the internal components. This was a question I wanted to answer for myself, but thought maybe someone else might want to know.

 

Running your engine at 7000 rpms isn't the issue. Its how many rpms you are spinning the blower. If you have a really low boost pulley @ 7000 rpms, the whipple will be spinning less than if it had a larger pulley at 6000 rpms. You'd need to calc out what size pulley you are going to need, then see how many rpms the whipple will be spinning at 7000 crank rpms. Parish8 will know better, but I seem to remember him throwing out 16000 rpms for the whipple.

 

I dont plan on seeing 7000,more like 6500-6600. But, yes I agree it could shorten the Whipples life span. But then again I think it depends on how often you see those high rpm's. My truck is a daily driver and will only see those high rpm's in short boost playing around. When I go to the track is a differnt story, but I only tend to make a handful of passes when I go.

 

I know what you're trying to say, but that just looks funny. It's when you said:

that I got confused. You said 'larger pulley', but meant larger boost, not larger diameter...correct?

Larger diameter pulley = Lower boost = fewer RPMs
Smaller diameter pulley = Higher boost = more RPMs

 

Any opinions on this...how will the truck run until I get it tuned?? I want to put about 1000 miles on it before I take it to Futral and let Allan dyno tune it?

 

You might have to open that hole up in the throttle body a little. How big is the cam again?

 

It's 224/230 581/588 114lsa

 

There might be a little massaging the throttle to keep it running at times. But yea .. it should run.

You will prolly want to get it tuned before your 1000 miles is up. It won't make much difference between then. The fuel trims will shape up on the dyno fairly quickly.

 

Naked AV, you are correct. I think that previous post was just accidently written backwards.
