Whipple 2.9 question regarding supp. mods

[Moreboost88]

Do you have to have a Whipple 160mm Monoblade Throttle Body(or Cobra JetTB)and

the whipple cold air intake with MAF, if you are only going for 650rwhp? I

currently have the JLT intake, and getting 72lbs injectors, do I really need

the throttle body and whipple intake? I called a local performance shop and

they said its not necessary unless you want to achieve more the 650 rwhp.

Just checking to see what your guys imputs are

Thanks

The throttle body is going to become a real restriction at that power level. You don't have to have the Whipple CAI, but I would consider at T/B pretty soon.

I'd go with the L&M TB for it's drivability. The Monoblade has nothing on the L&M performance-wise.

Is the "van down by the river" in California? The CARB approval sticker makes a difference if you're in Cali, the only way you can do it here, and all the 2.9 Whipple packages come CARB approved.

I'm getting ready for a 2.9 as well and looking for 650whp, I'll be buying the SC and CAI package. safdchi convinced me on Whipple's CAI, it being large and able to run w/o a MAFia were the two reasons. Will you be upgrading your injectors? I'm considering Lethal's 72lbs. stock height injectors, still on the fence about them and might install the SC/CAI/Tune and see where the hp/tq falls; I also have a BBK throttle body that I'm going to try out.

Ok, i will more than likely get one, just undecided on what one to get

I'll look into that thanks!!

No, I don't have any CARB approvals in my state, yea i'm going to upgrade the injectors to 72 lbs. I think I might get the whipple CAI too due to the MAF, i am still unsure about the throttle body and which way to go. Thanks for you imput
