Anyone have any IAT info for certain blower speeds for the 2.3L whipple?
Also any additional info regarding pulley sizes, power output, oiling is welcome.
Also, I am seeing the traditional rear entry (AX) version can support a few extra HP's... At least that's what they say?

The specific engine/blower combo I'm researching is a 500efi punched to 509. Larger cam. Stock 500efi heads (upgraded springs/rockers/lifters) and stock compression.
Top mount rear entry efi blower. Standard IC's. Currently it's seeing 5psi with 8.75lower and 3.375 upper. Keeping rpm at 5600 so max blower speed currently is 14,518. I'd like to toss a bit more boost at it and not sure what's safe or not. Whipple says 18k max on the blower itself but that would be a ton of heat IMO. Who's done what with the whipples?

IAT info .. good one buddy.

It's not a cam or head thread... I know, lame right? It may get there like every other thread tho

We usually set them up at 300% overdrive. We use a 9" on the crank and 3" on the blower on engines that generally turn around 5566-5600 rpm. That puts the blower in the 16,500 neighborhood.No issues at all with that speed. We've done more 2.3 side mounts then I care to remember. Give me a shout if you have any questions.

you have a set up for v-belts?

Thanks Eddie. I actually did PM you on Facebook messenger. No response yet. I appreciate the info. So I should be plenty safe going from the 3.375 upper to a 3.125... That takes me from 14,518 to 15,680 blower rpm. This enough change to justify? According to whipple site this should put me around 6.5psi. I don't need to set it on kill, just like to utilize it if its there and safe.

I use a separate V belt pulley, like the one from Whipple. We use one that has 6 threaded holes in it. Then I just buy a 16 rib 9" pulley from Whipple and bolt it to the v pulley. You will need a spacer to get the alignment correct, but that isn't a big deal. They only way they offer the 9" pulley is in a 16 rib.

[QUOTE=Eliminated572;4520182]Sorry, but I never got your pm. If we aren't friends on Facebook, it ends up sticking your message in some forgotten folder that is impossible to find. I won't get a notification that it was even sent. The best bet is email or phone, since I'm only on Facebook when I have the time.
You should have no problem at all going to a 3 1/8" pulley. IAT's should barely be affected, if at all.

IAT- Intake air temp.

I stand by everything I said on the weekend Chris!!
