Whipple question - what mods get me to mid 800s or pushing 900???

I am super curious what you get out of that. I assume on 93?

Have the Stage 2 stuff (120mm TB and Whipple stage 2 canned tune) ready to go in, impatiently waiting on a 3.650” pulley instead of running the 3.750” the kit came with. Added a fuel pump voltage booster for piece of mind. Thinking this is as far as I’ll go. Famous last words.

Installed the 112mm TB w/intake boot, 3.625” pulley, and the canned Whipple Stage 2 tune last weekend. Sticking with 93 octane only. Need to find some time to get on a dyno. First impression; rowdier and boost comes on sooner in RPM range.

I just cruise around and whenever I feel like it casually GAP THE FXCK out of whatever.

including Lambs, Rari’s, Mac’s, Z 0h anything’s, ZR anything’s… vipers, 500’s, S550’s … other S650’s… put a bus on a new Shelby GT350 last weekend.

and then go back to slow poking in 10th getting 25mpg’s

Is there any downside to the 120mm throttle body?

In your opinion is the 3.625" pulley safe for 93 octane?

 

[Q6543]

No, go BAP/E30 or something to get more octane.

120 may need a tune update… call VMP, Justin should have the answer

I don’t pretend to be an expert with any of this, was told as long as I had a fuel pump voltage booster I’d be on inside edge of safe with 3.625”. I’ll ultimately swap in the 3.750” that came with Stage 2 stuff. Just wanted to try it out for fun. Where I live ethanol fuel isn’t that common around my parts.

reliability

 

[Junkyard Dog]

Of the throttle body or something else (like the engine)?

The 112mm is more reliable?

the throttle body there are some bad ones where it catches on it self with differential heat expansion causes a code and limp mode
last gen alot of issues with aftermarket throttle bodys not just the one

they may have fixed it in the new generation but i got the gt500 throttle body to avoid it
