I posted question here.


Toyota V8 with 2300R blower

I don't have any reason why this forum doesn't have some moderator's that answer questions to us quickly BUT "For Sure" I know that if you call or Email Whipple...... they respond quickly and professionally.

I have a 2003 Yukon Denali with a 2.3l dual belt kit. Will any other larger blowers fit in place of the one I am currently running? Will the 3.3 or 3.4 fit with some modifications?

I have one of the whipple supercharger systems for the 1998 350 Vortec, but the part that actually bolts to the intake on the engine doesnt have the auxillary injectors in it. What do i need to do ? Can i change the engine injectors to a larger lb per hr ? I also have the stock fuel pump, do i need to replace it with a higher volume one? Would you recommend the whipple electronics or getting a custom PCM tune?

I have an isssue with my super charger! I have a 97 gmc sierra with the 7.4L in it with a whipple supercharger added. I had recently took it to the shop to get the intake gasket re done on it, when i got it back it sounded like a bag of rocks in the back side of the supercharger, just at idle. The mechanic told me he contacted whipple and you guys told him it was normal and it could get louder!!!!! If you could help that would be great because i dont know how it could get any louder and still be drivable and i really dont want to tear into it if i dont have to. Thanks

Step No.35 in my 2004 F-150 install manual stated;"35. Reinstall the factory coil packs, tighten coil pack securing bolts to 53in/lbs Loctite™ (#242 blue) threads." There does not seem to be a set to remove the coil packs?

Hey mike I hate to pile it on, But I need help with getting info on a tune (98 7.4 whipple first gen plastic control box) How is boost controlled if the box is removed for larger injectors and tune? what size injectors do you recommend (has headers) for up to 7 lbs. boost? Is the return line shut off solenoid still used? What is retained from the whipple kit and whats not after a tune with larger injectors Thanks.

Hi there. I have a 4.0 Whipple on a LQ9/408. We set her up and tuned her to get the system stable before tweaking it. Will Meth help the IAT's? If so should we spray it before or after the screws?

i have a 97 yukon that i just installed a whipople charger on, its putting out 6psi, it was running great for a short peroid of time,now the light for the whipple dont come on at all and when you get into the boost the check engine light comes on.a code p0108 comes up and its the (map) sensor circuit high input.already looked for vaccum leaks what could be causing it?

Good Luck getting an answer... This forum is soooooooo dead.
