Choices with Whipple

[ToddB]

Use a 3.875 and you will be at 10 psi. That is the first one I used with my LS 9 cam and I was right at 10 psi

Does anyone have a used 3.875 they want to sell?

Of the 3 pulleys I got with the kit I bought, the only one that looks right is the 4.00. I thought I had a 3.75 but its a 3.625 with the wrong spacing. And the 3.50 has different spacing also, but is way closer to the 4". So if anyone has a good used 3.875 or 3.75 I would be in the market asap.

I have a question

hello everyone I just joined here , 2 days ago I bought a 2011 Camaro with a whipple charger

I do have another car but the Camaro will be my main car so I will be putting about 15 thousand miles a year on the camaro , and I want to be able to constantlyromp on it without blowing the engine

my car has the 3.875 pulley (10 lbs) but I was thinking of lowering to the 4.250 (7.5 lbs) just to make the engine last

so my question is should I lower it or keep the pulley in there now ?
will the engine truly hold up if I run the car hard as a daily driver putting 15 thousand miles a year on thee car ?

I want to keep the car for 4 years (it only has 3 thousand miles on it right now)

thanks for any help and I figured this question would be the same as the original poster was asking kinda sorta

Yes but it's a weekend car. Not many miles on it just about 27'000 with 8'000 after forging the bottom end.

Thanks for the feedback. I'm just trying to gain information and figure out how my car should be set up for longevity.
