Whipple 2.9 Kits @ Lethal Performance

So no info on this? Because I know if us commoners go for 17psi with the mods listed in starting post, Lundracing will not tune for it, and if someone else does they will put a new window in their block.

What's missing? Race gas? Sleeves? Something other than a BAP? Nitrous?

I believe they used MS109 fuel and pump booster, that's it!

Yes this is a 100% stock engine, never been out of the car. SC went on in the first 1000 miles, Lund Racing tuned it. ID1000 injectors, JMS BAP is the changes to the fuel system. No return style system.

They ran MS109 which is quite incredible.

You don't need to keep it under 7000. We've got 30k on one of our test cars and 20k on the other, both have massive abuse, near rent a car status lol and no issues. Shelby tracks most of there cars, never an issue. We have thousands of customers running, no issues. Roush also revs to the same rpm, no issues.

I wouldn't offer something that I wouldn't run on my own car and we wouldn't offer a warranty if we felt poorly about it.

11-14's were more problematic, but the 15+ doesn't have an issue. Now if your going to build a race car, built motor, then it's no question a good choice but it's just not needed for daily drivers and stock engines.

We keep hearing the 15 have thinner timing gear and the 14 and make is more fragile.

We have well over 1000 of them out there running, not one failure that we are aware of. Including many race versions.

Also passed durability testing at 200+mph during the calibration phase. If it passes through the testing we put on these and it passed Roush/Ford Racing durability testing at same RPM, I'm confident that it will not be an issue for DD.

17 psi? Uh.... there is something missing in this build. What size pulley? What type of fuel? You are doing this with a BAP?

We were running MS109 fuel and I believe it was a stock lower with a 3.50" upper for the 17lbs! That is correct we just have the JMS plug and play BAP. When the JMS FuelMax is engaged it will support up to 1000HP with the proper injectors installed!

Chris do you know if the car has a Torsen diff or Traclok?

Are either of the Whipple GTs 6R80 Autos?
Have yall tracked them or added transmission coolers?

The car is a PP car so im assuming all they did was swap ring and pinion so yes it has the torsion diff:cheers:

We are still running the Torsen in our GT. I'm actually kinda amazed it's holding up as well as it is.

We're running a 3.50" upper and a larger lower in the 10 rib setup. MS109 fuel, ID1000's and a JMS fuelmax.

Stock motor, stock MT-82 trans.

Let me know if you have any other questions.

Thanks, Jared

Your power pack Whipple kits on Lethal's site, do they come with software from Whipple for the flight control? I have a Lund nGauge already and was just wondering how the initial install works for a tune to run safely until you can get your remote Lund session.

You pick either Whipple or Lund but only Whipple has the Flight Control features.

There's some changes that just took place today regarding the Whipple kit (Not the packaged kits we put together) for the 2015 GT. From here going forward here's how it will work for all of Whipple's complete kits. The price of the kit is going up by $100.00 but will include the Whipple flare tool that does have the flight control option.

Before if you were to add the Flare tool with flight control option it would be a $200 upgrade. So you're actually getting a better deal now with the Flare tool being included in the kit as a standard option.

You'll still be allowed to delete the flare tool w/calibration for a $200.00 credit if that's the route you want to go.

We will be adjusting pricing on the site which should be active on the user end by tomorrow.

As for our custom packaged Whipple kit. The only way you'll be able to run the Whipple cal with flight control is if you don't install the ID1000's that are included in the package as the Whipple calibration isn't made for those injectors.


Hope that helps.
