It seems like the complaints about the TSX are about its tires and suspension settings.. NOT engine.

Now, being that suspension and tires are pretty much the first thing that Cunningham would fix... and that the J35 is pretty potent...

My only concern will be the LSD... Can Cunningham put an LSD on that J35?

I also assume he'll be running the MT6 from the TL.. a good thing.

So, will the LSD make or break the car for racing?

The rules must be written very favorably for this car to even be competitive. A heavy, NA 4-cylinder, FWD car competing against Caymans, Boss 302's, Camaros, Audi TT's, Evo's, etc. and finishing runner up for the season. Certainly a tribute to the Realtime team and drivers, but that car honestly should be last or next to last based on the engine and drivetrain configuration.

I wish them luck with the J35, it's a shame this car only came in FWD. With SH-AWD it would be much more interesting.

I agree...the 4 cylinder TSX must have had a very favorable lower weight limit compared to those other GTS classes. I was a big fan of the series until Speedvision changed over to 24 hours NASCAR SpeedTV and now i can't find it anymore. I would have loved to see how the SH-AWD would have fared in a racing series.

It's mainly about power to weight.

A properly set up FWD chassis in a class that allows up to 300whp to be competitive looses very little to a RWD chassis.

I defy anyone to find a better 2 litre "sedan based" race car than a K20 engined EG or EK, short of the top professional series like WTC or BTCC where the FWD chassis needs a small weight advantage to stay competitive.

I am not sure about spec for this series, but keep in mind that this car (in race trim) is probably 2500 lbs or so, and K24 if permitted, can easily(for the race team) get to 300WHP.

If anything they were probably lacking in lower rpms, where TQ difference would be more present, starting, pulling out of slow corners, but I am certain that their handling was top notch and most likely they had fastest flying laps.

With V6 they will probably gain something because of the bottom end, but handling is not going to be as good, so it is sort of a trade off really.
I am curious how this will map out and how long it will take to sort things out.
One things is for sure, if anyone can do it, this team can...

Okay, rules are pretty limited for WC, including GTS in terms of power adders...

Can balance engine, but no parts swaps from other K or F-series motors like NASA Honda-Challenge, so no 300whp k24 motors in GTS TSX's are likely ;)

So how are they competitive...looks like competition is balanced using 3 methods: 1) intake restrictors (section 2.3.4.5: Inlet Air Restrictors - pg 32) 2) tire/wheel size limitations (Appendix A) and 3) minimum weights (Appendix A)

Rules: http://www.sccaproracing.com/files/misc/2012%20PRR%20V01.2.pdf

Ouch... looks like the P-car has a big advantage there - biggest engine, 50 pounds lighter than the Acura in A.3.2

Interesting that RTR uses an airbox between the throttle body and tube, which I assume routes to a cold air source. What is the reason for this?
