Whipple performance on road race track?

[CT22]

Who here has a Whipple on their GT or DH and has taken it to the road race track?

1. Any over heating concerns or scares?
2. how is the power coming out of corners, manageable or constantly breaking the tires loose?

I track my DH so planed on keeping it NA. Had a turbo on a 911 once and didn’t like it. But I just got smoked on the highway by some little fucking something, I don’t even no what it was and I’m pissed. Re-thinking forced induction now seriously.

perhaps a centrifugal like a ProCharger is better for rad race focused set ups? But then why would the GTD have a Whipple looking one on top?

Feedback on your experience with this dilemma appreciated. Thanks folks.

@CT22 ..... was out with a friend who has a DH earlier this summer later at night. Some $hitty little rice rocket with 4 baby teens were in it. He ran it hard off 6 stop lights in a row. On the 7th pull the $hitty little rice rocket blew up, shooting parts and oil all over the road. Most of the little $hit cans can't sustain constant pulls, whereas the DH can pull all day long. There is justice - you just have to wait for stupid to come to you! I do get 100% what you are saying. Twin turbo it and you'll have 1200 WHP. RSA has one and they have won beaucoup money with it - bankrupting a lot of $hitcan owners in the process.

i’ve had my stage one on Apex motor park in Arizona. April, mild temps. Call ran strong. in track mode, Throttle delivery was a little bit more linear. You can control the power coming out. Just make sure your tires are pointed where you wanna go No heat issues in regards to the blower. Was more concerned about oil slosh & brake fluid. 4-5 lap runs then I let it cool down. Drove it hard then it drove home like a Sunday driver

I'm pretty sure the GTD has a 2650 PD blower.

I'll speak to what I have: My GT has the pp and the extra cooling. I have the stage 2 Whipple and I have yet to take the car to a road coarse bc I bought drag radials for it and it's gonna be a minute before I buy a 3rd set of wheels and tires.

I'm impressed with the cooling of the gen 6 3L Whipple. The car has never seen engine temps past the 220s or 230s oil temp. I don't have a diff cooler, so those temps tend to get higher than the engine oil temps and I suspect that if you don't have the DH handling pack with the diff cooler, that will be as big an issue as the engine and oil temps. If you have the HP with the coolers, forced induction will be fine.

If you don't have the coolers then don't boost it unless you plan on also adding all the cooling upgrades to the car.

As far as the argument for a centri setup, it all depends on what you really want to do. If you want light-to-light action and immediate power on the street, can't beat a PD blower. If you have a MT I would recommend a PD blower. If you have an auto, you can go centri and the car will stay in the powerband pretty well.

Make sure you are confident about your decision before going for boost.

People get the stock cars to overheat.

And, the GT500 has six heat exchangers to help handle the heat

thanks for the feedback y’all. Appreciate it. @Efreita at 4-5 laps would you slow down because the temps were getting high?

I have all the cooling stuff from the factory but will likely look for what else can be done. I live in Austin and like to run at COTA. It gets hot here. If I can be sure sure to get the temps down I would like the PD over centrifugal. but I also don’t want to lose my strut tower brace lol. Oh the decisions we go through while modifying our cars Lol.

if anyone else has specific road race experience pros or cons with superchargers, please share. Thanks!

no, I was just playing it safe. I had no limp modes. Brakes were the biggest concern- I have the pp brembos. Was concerned about brake fluid boiling. Now the car definitely has high heat fluid in it because I had it drained and replaced. Car ran mint

Ford puts high temperature fluid in the brake system at the factory. Boiling the brake fluid should not be a concern at the track with your Brembo brake system and performance package.

Thank you for posting your result at the track, though. That is the first personal experience I have seen posted with forced induction added.

Did you track it before adding the blower, too?

What tires did you use at the track?

I did not track it before I did the Whipple, I did the Whipple the weekend I bought the car. And as far as the tires, I had on the stock Perelli P zeros 255 in the front 275 in the rear, they held pretty good. I got some videos, but the files are too large to post here. Thanks for the input on the brake fluid. I had found that out after the fact. I will be doing more track days as the weather’s gonna cool off here in the Phoenix area in the next month or so. So I will be able to update on my findings . My car is currently getting upgraded to a Whipple stage two with headers and a few minor other additions. So I will be able to give you information on How the upgrade holds up on the track

I'd be more concerned about the rear end overheating than problems with the engine.

With the engine you can see that it is getting hot (coolant temp, oil temp, trans temp) but there is nothing to tell you when the rear diff is getting too hot and it had been an issue on S550 and S650 cars

Mine has a differential temperature displayed on the dashboard, but are there a lot of differential failures on track for overheated differentials during HPDE track days on street radial tires? I doubt it.

Since you say it has been an issue, maybe you know more about it or have seen it frequently. Over at trackmustangsonline.com I do not see differential failure discussions, but differential coolers are a popular add on modification for some of the cars.

did you have those concerns when you were on the track with your supercharged Mustang?

LOL, that is going to be fast. What size pulley(s) and what size throttle body are you using?

I can also say that the diff will likey be a bigger issue without a diff cooler. I do have a diff temp gauge with a PP but no cooler. I have a stage 2 Whipple and headers with extra engine cooling and oil cooler and at times the diff temp gets higher than the engine oil temp, and that's not on track so on track it would def be an issue. I wouldn't track one of these cars without all the extra cooling.

i’ve had my stage one on Apex motor park in Arizona. April, mild temps. Call ran strong. in track mode, Throttle delivery was a little bit more linear. You can control the power coming out. Just make sure your tires are pointed where you wanna go No heat issues in regards to the blower. Was more concerned about oil slosh & brake fluid. 4-5 lap runs then I let it cool down. Drove it hard then it drove home like a Sunday driver

Just curious whether you have been back to the track since April?
