I was curious about that as well. What's the possibilities on a stock long block with full bolt on and whipple.

E40 ... Looking at 700-730 safely. Most do cam swaps for increased fuel lobe. While you will not run out of fuel in a traditional sense, you will run out of fuel in terms of time (injection cycle). Options are slowly hitting the market for those who do not want to do a cam. LPE/Katech/FIC injectors which could potentially increase fuel by 30% +/-.

Meth works well though

As Ted said, with this Whipple you WILL find the limit of the stock fuel system. I'm glad JRE has this unit now, Weapon X has disappeared; and this unit on the CTSV is making gobs over power. This will legit be a Demon killer.

What fuel system upgrades do you have?

If all stock I would say up to 750 RWHP but E40 might not be enough Octane. so I would move to E-50-E60

I think the low side pump will run out first so a fuel pump voltage booster is a real good Idea.

I would be comfortable up to around 750 RWHP as long as there is some safetynet left in the fuel system.

On E-85 we were running out of fuel at 730 RWHP so we stepped it down to E-66 to leave room on the fuel system.

Very true.

I think GForce Motorsports in Houston was making over 900RWHP with this blower on a V3 CTS-V. I am not sure on what other supporting mods it has since GForce would never respond back to me on IG or FB. It's super annoying when tuner shops do this. Oh look, a Whippled Caddy making over 900RWHP and not listing any other mods like it's some kind of industry trade secret.

Confirmed 911/889 w/cam, meth, headers, intake, 14#, ...
fuel system (M1) can in picture, heads (port)

Another picture listed 880rwhp on boost only.

Curious, does this kind of power upgrade overcome the nannies? I mean, can they possibly keep the car under control assuming you left them on with a Whipple tuned to the max?

Quoted their FB post, but yeah some more details would be nice. I'll ask next time I see him.

Cam, Ported LT4 heads Whipple 2.9 Supercharger G-Force Fuel system ARH Headers. Made 850 rwhp on straight 85% and with E85 and a blend of C16 it made 919 rwhp

The traction control and Stabilitrak still do a good job of keeping it under control.

Anyone get before/after numbers or expectations for 1.7 Eaton to 2.9 Whipple just on its own?

This is where Weapon X failed, they insisted on slabbing together performance packages instead of real world blower performance.
Expectations are 70-100hp , at same boost levels.

If you don't change the boost it is likely you will not make more power.

Boost is a product of restriction.

The restriction is the engine and exhaust system.

The whole concept behind a larger supercharger is.

Room to grow

Less heat at high boost.

More efficiency at Higher boost levels.

Less blower speed to move more air.

Larger intercooler cores to remove more heat from the pressured air.

You can simply spin your stock blower faster but you quickly move outside the efficiency map and start to produce more heat and run out of blower.

The Little 1.7 blower is already wound pretty tight from the factory so there is little room to make more power.

Hope this clears things up a bit.

Your explanations are always spot on. I wish I could explain the above as deftly as you do when people with the LSA want to put a 2.55" upper and 9.55" hoping to hit 800 RHWP
