Default Subaru vs. Vipers. Whelen US TT and Dodge Viper Cup NJ (in car video) + 2nd video

The Whelen US Time Trail Championship is a new series this year that runs side by side with the Dodge Viper Cup and the US GT Championship series. After speaking with the promoters this sounded like a really great event to put our Subaru up against some fast Dodge Viper ACRs and ACR-Xs.

With our car actually being TT-1 legal, I initially was going to put in that class (with a tire change) but decided it would be nice for a change to uncork the beast, so TT-Unlimited it was going to be! Knowing I might face Dodge factory driver, Kuno Witmer in the factory Viper ACR-X I was both nervous and excited. I had faced this combination before at VIR where the duo clicked off a 1:54 lap time. Not sure why exactly but Dodge only had Kuno go for the lap record attempt on Friday, setting a new production lap record for NJ Thunderbolt (with chicane) at 1:26.(7 I believe) but there were other ACRs and ACR-Xs to run against.

Setting out on the track for round 1 behind Steve Katz in the Viper ACR I didn’t know what to expect. Having to bed new brake pads in I was happy to play follow the leader. Running in my NASA trim (510 HP) I settled in the brake pads for two laps and then started pushing on Katz. I could tell he was pushing it as the big Viper was pitching in the turns and power sliding on the exit. With the cool morning temps and a green track I was able to take the chicane flat out and I easily diced inside of the Viper to take the lead. After the end of the session we definitely set the pace for the rest of field with a 1:26.07.

Knowing I had so much more in the car I was really happy with that lap time. Going faster however wasn’t meant to be as temperatures approached 100 F and the Viper Cup cars were greasing up the track. What I got away with in practice didn’t treat me well later in the day (as you’ll see in the video) and taking the chicane and last turn flat out just sent me off the track damaging our front splitter. I ran a number of 1:26 laps but couldn’t improve on my morning lap time. That was fast enough however for our Subaru to take the win on day one over the Vipers by 3 seconds.

Knowing from day one that lap times were really a function of temperature and track conditions, I knew the first session would be the one to let it all hang out. This was no to be however as the Viper Cup qualifying had a car blow up and drop oil around ½ the track. The clean up took hours and we missed the coolest session of the day. Not one to give up we dialed up the 600 HP boost level but suffered from electrical issues taking out the boost controller, water injection, and our transponder all at once. This continued to happen after dissecting many layers of problems. On one lap we managed 600 HP for at least ½ lap running 1.5 seconds faster to our split than our 1:26 runs but shortly after that everything shut down again dropping HP down to 400 but I still ran in the 26s. In a last ditch effort we rewired everything and everything independently after finding out due to the high engine bay heat the wires on the water injection valve had shorted due to the sheathing melting. Well on the last session we at least kept the transponder and the boost controller working but the water injection system shut down again likely due to the valve having too much resistance now, which automatically drops the Hydra EMS into a failsafe mode reducing power (watch the video and you’ll see on my last lap the water flow meter suddenly stop).



It always feels good to win!

TT-Unlimited championship points leader Carl Kafarowski, who won the class at both Chuckwalla and Sebring, could only manage fourth fastest both days. Kafarowski set his fastest time on Saturday and couldn’t match his effort on Sunday. Both days he was trumped by Steve Katz and Michael Von Quilich (Viper ACR-X). Von Quilich was on ‘double-duty’. The North American Road Racing sanctioned event also featured the Dodge Viper Cup presented by Pennzoil, in which Von Quilich was also driving, along with the US Performance Driver Education program and the US GT Championship. He went on to finish 3rd in Saturdays Dodge Viper Cup race

George MacDonald finished on top in Saturday's TT-1 competition ahead of Doug Wind in his SRT-4 by just over a tenth of second, setting a time of 1:33:543 to Wind’s 1:33.647.

Thanks, you really have to be as our exit speed is about 130 MPH. You just need to open up the wheel and ride it out

Funny you bring that up...I told my team, I don't get DQed for going off track in this series so expect me to go off today . It's kinda hard to know how fast you can go without sampling a little grass here and there

Here is the official press release sent out by the organizers:

Nice drive Phil. Two wheels off is better than four. Is the dry sump a plug-n-play setup? Shoot me an email or call me about it.

I agree but sometimes trying to turn a 4 wheel off into a 2 wheel off ends up crashing people. If I'm going 100+ MPH I usually just open up the wheel and bring her back on track slowly

The dry sump is as plug and play as a dry sump system can really be. We sell it as a 100% complete kit or minus hoses and hose fittings.



We use a combination of ARE parts, Aviad, Aeroquip, Element, and some trimmings here and there (different belt) depending on how the tank will be mounted (cage, etc).





Adding this to our engine package on this race car was the best thing I've done in a long time! The whole system just solves the oil starvation issue everyone gets at this level and on top of this it also solves excessive oil blow-by caused by loose rings or the fact that the oil sits in the heads around high g turns (which in turn pumps it into your catch can).

Very well sorted car. It tends to be rare to see a race level car that "easy" to drive. It's one thing I've attempted in my own endevors with good success, albeit way down from your level of a car. I don't want to say the car's a walk in the park, but it's definitely sorted well enough not to give you surprises which provides a massive amount of confidence in the driver to really push the car. It seems to take a lot of people a lot of time and trial and error to get to such a point with car setup.

Really? I usually just yank the wheel whatever direction the track is, and hope I don't die.

Well done. I still need to install a surge tank for the fuel system, and that dry sump setup looks tempting, although I don't think it's worth it at my current prep level.

I agree, biggest mistake most people make in an off is to jerk the wheel hard trying to get back on. Just ride it out and reenter the track in as straight a line as possible. I'll give you a call about the dry sump. Do you still run an oil cooler?

I run only the OEM oil cooler and now with this dry sump it holds 8 quarts of oil with the tank only half full (This is the proper way to set the system up so the tank acts as an air/oil separator to not only allow the engine to breath via this tank, capturing blow by oil, but also so the air can escape from the oil before returning to the oil pump.

I also really put this system to the test that weekend because that big off smashed the splitter mount against the oil line pushing it right against the header burning a hole in the oil line. Because the two port scavenging pump has two separate chambers it will not lose suction if one line or pump fails . We had spare -12 socketless hose handy and were able to make an easy trackside repair by heating the hose ends up in the engine compartment and slipping the fittings on .

You would be surprised at how affordable this complete system is as it's similar to some partial kits on the market. I burned up 3 motors since building this new car which has way more grip than our last car due to improvements in our custom BC coilovers and the Fulcrum Aeroworks rear wing.

For the guys that have already purchased the dry sump from us I've told them all, if you can afford it, there is no downside to running a dry sump. For many of our customers who track their car and have $10k+ in a built engine it's a sound investment.

For you I think your grip level isn't there yet but once you start going 1:17s at Summit or 2:00 at VIR it's time to start thinking about it.

Phil, can you please PM me with the price of the complete ready to bolt on dry sump system? I'm also interested in the BC system you are running too for my 05 STI.

You're right this car is extremely well behaved. There are two major contributors to this, one was the new suspension setup that settled the rear wheel hop and added a small amount of push. I'm able to push very hard into my turns now and you can see this in the video. The other reason is the Fulcrum Aeroworks rear wing. First off it has the least amount of drag and more downforce than any other wing I could find. Secondly the shape and size of it allows huge amounts of slip angle while still creating downforce. I can't stress how much easier it is to catch the car now when it gets sideways! In the old car when I started to drift the old wing would simply lose downforce and I usually ended up spinning or getting into a major tank slapper

Dang, I have your high$ engine and your custom BC suspension, I guess that means I better get the dry sump! If I could figure out how to put a big ol' wing on the wagon I'd be really set.

Yeah I've been worried about you with those fast lap times!

If you want to get a wing on there I'm sure Fulcrum Aeroworks will make a custom wing for you. They are also not ridiculously far (Texas) from you. My wing and all the wings I've sold from them are custom per application so if you need a unique mounting system I'm sure they are up to the challenge.
