Right on, so when you opt for the HP tuner it comes with base tune. Good to know. Cant wait tell you drive it and report back.

It would be nice to have numbers for the can tune and custom tune

Whipple PSI to PSI will make more power. It’s just the efficiency of the blower & decrease in Parasitic loss. Quite a larger blower as well. factory 1.7L Eaton was the same size unit that was on my old 2004 SVT Cobra.

Other than the lingenfelter pump what are all your fuel mods? Are you running a different?

That looks awesome can't wait!

I called whipple the other day if I remember this will not come with a CAN tune.

Comparing it to the Cobra is not very fair, the only thing in common is its 1.8 to 1.7 small size. I'm pretty sure the Whipple has to run at much higher boost and would put out less power at 10 psi than the factory 1.7 (don't think they make a pulley large enough to get down to 10 psi on the Whipple). Test on the CTS-V3 showed it took 14-16 psi to gain 35 rwhp over the stock pulley 10-11 psi 1.7. Pulley that 1.7 to make 14 psi and I doubt there are any gains in overall power with a Whipple but the IATs would be much lower. The nice part about the whipple is that 19-22 psi is attainable without overspinning and turning the blower into a blow torch. Thats when the real gains happen.

At the begging of this thread it seems like a lot off people are confused about PSI. just because the psi is less doesn't mean its going to make less power over another unit. You have to look at how much air is being pushed through or volume. Lets face it GM did great with what 13 or so heat exchangers of course not all them for the SC but, a smaller unit just can't move enough air like a larger unit and once you pulley down the heats up.. hence the use of meth!

The whipple gonna move more cold dense air at a lower psi plane and simple.. so just change your thinking a little bit its not the PSI but volume of cold dense air.. If its a big unit it can compress more air at a lower psi.. small unit high psi less volume. both have there pros and cons.. when your talking all out power the unit that moves the most air, cooler.. wins..


Edelbrock 2650 article: I found...

First, a little trivia.

Can you name Edelbrock’s best-selling supercharger application for this past year?

Not a Camaro. Not a Mustang.

It was the diminutive 1.32-liter model designed for the popular RWD triplets of Subaru BRZ, Scion FR-S and Toyota GT86. That bolt-on blower added around 80 horsepower to the 2.0-liter FA20 Boxer engine and about 60 lb-ft of torque.

“It runs in cycles. The previous year it was the C7 Corvette,” says Edelbrock marketing boss Eric Blakely. “That was an interesting project because it was the first time we developed a small supercharger. We pretty much got a lock on the V8s, but there was considerable amount of testing to get the 4-cylinder blower down.”

Big engines will again be the all the rage next year as Edelbrock finishes up development work on a new line of superchargers that spin Eaton’s latest 2650 rotor assembly.

“It opens up our options to design packages for bigger displacement engines and to really shine in Stage 2 and Stage 3 applications,” says Blakely. “We’re looking at Hemi kits, late-model Mustangs and the Camaro and Vette engines.”

As the customer power demands have gone up for popular V8 engines, Edelbrock’s stalwart blower, the 2300 model, is in danger of falling out of its efficiency range. The new Eaton rotors are 15 percent larger and will push 25 percent more air at 18,000 rpm while delivering 14 pounds of boost. Best news of all, Edelbrock doesn’t have to retool the blower housings, which will help speed up the introduction of the new superchargers

“We anticipated that larger rotors would be coming, so we originally designed in extra metal in the 2300 housings that can now be machined to accept these new rotors,” says Blakely.

The new rotors are still a 4-lobe design but now have 170 degrees of twist compared to 160 degrees on the 2300 model. The extra twist shortens the rotor lead to help maintain efficiency at higher speeds and pressure ratios. Other features include larger bearings, thicker timing gears and pressure relief ports in the bearing plate to help reduce friction. Initial testing by Edelbrock shows the 2650 can outperform competitive 2.9-liter superchargers.

“We could even go big-block with this blower,” says Blakely.

More information on new applications with the 2650 package will be coming in 2017.

There's no question that the Whipple really shines on more advanced Stage 4 and 5 builds. We've seen Vengeance, HHP and more make 850-950+ RWHP with Heads/Cam. But the swaps on stock-ish Stage 1 and 2 builds are NOT netting anywhere near the power that I'd at least hope for. As noted above, it took 14-16 PSI for the Whipple (Around 70%-80% of what it's capable of) to make just 35 more RWHP than a 1.7L Eaton on a stock engine (No cam, no meth, no heads, no porting, no E85 etc.)

BUT, running it at similar boost with Meth/E85/Heads/Cam has shown it can make ~900 RWHP...Which is easily 100-150 RWHP more than the stock blower would do with those mods.

[EDFHOBBIES]

There is no Power mainly because no fuel.. 610 rwhp with 1.7L and 680 rwhp 2.9L that's average where fuel runs out.. but to get those zl1 figures a intake and headers system is required. The whipple should bolt on 125 w no other mods correct?

Unless your going for records I thought forced induction didn't require porting like a NA car.. or DI heads no bueno?

Still wouldn't even worry about psi changing blowers adds 125 you can pulley all you want you want get 125 out of the 1.7 with out other goodies

[Redline Motorsports]

Hey guys here is some clinical data. We did a few tests a couple weeks ago on a 2018 A10 ZL1. This is stock vs the Whipple with a 4.00" pulley and stock lower.

When we get a chance later this week we are going to bump a few more lbs in the mix which should yield some more ponies. The 2.9 making about 2 lbs more then stock so this gain is showing the larger blowers size and efficiency over the 1.9 liter.

Will update after the next test.

I hate how it appears a cam seems necessary to make any decent power above what basic bolt ons and tuning will get you. What if you want about 700-750 rwhp but don't want to crack open the engine? Guess you're SOL.

A Procharged setup or similar Centrifugal blower can and will get you 700-750 RWHP without opening up the engine if you use Meth or E85, which shouldn't be a big deal to somebody who wants that kind of power. A fuel system upgrade may be necessary but again not that big of a deal. It's true we don't get anywhere near Hellcat engines with boost only, but our gain is once we get past stock-ish/boost only builds and move into bigger builds, that the LS and now LT really shows off.

I've seen this idea from you a few times now...There's PLENTY left in the fuel system. Fuel system doesn't STOP power from happening UNLESS you're actually running OUT OF FUEL. And these tests are NOT anywhere near that. The LT4 Fuel System can do 650-680 RHWP on 93 with no assistance from Meth/E85 or a Cam's fuel lobe.

Again, fuel systems don't stop power from happening unless you're actually running out of fuel, as in injectors/fuel pump and lines are maxed, and the dyno graph will flatline and suspended use will result in good-bye engine.

The Whipple, when bolted on to a stock engine, is no where near 125 RWHP gain. Redline did just show they got 98 RWHP with 2 lbs more than the stock 1.7L blower, with the 2.9L Whipple. But you can bet that is with tuning and not with any shitty "Canned" tune that will be designed to be safe and universal...I'd expect half that gain with a canned tune.

Drill the blower for 8 fuel injectors and add another system.. with the cam running the pump limited.. or tune on c16


If you could mix 93 and c16 exctly the same every time on tune on it come out cheaper than ordering barrels from sunoco
