Ofna GTP On-Road

[CurveTracer]

This purpose of this thread is to focus on all aspects of the Ofna GTP on road performance including but not limited to chassis and drivetrain setup, handling characteristics, and overall racing performance. Let's get these cars performing at their highest level in GT class racing.

What differential fluid weights have yielded good results towards neutral drivetrain performance for:
1. high traction, technical course ?
2. low traction , technical course ?

I picked up a GTP II that I'll take to the April Las Vegas Montonica-sponsored race at the Silver Bowl. My interest in the GTP II started as my frustrations grew with the 2-speed unit in my IGT. So I'll be trying out the two-speed clutch-style unit in the GTP II and we'll see how it goes.

If I like it then I'll consider racing the GTP II in our on-road (parking lot) club racing scene in Utah.

For the April race I'll likely try 50K oil up front, 10K oil in the rear, and the I'll use the clutch-style 2-speed in the center.

Let us know how the setup for the GTPII works for your.
Nitrohouse is out of stock right now, so I'll have to wait on my purchase.
The NcClaren body is not available ... due to license issues. I picked up a Merc. CLK instead. Nitrohouse will be stockin some "generic" bodies to replace the McClaren style.

The newer version of ofnas 2 speed unit is far superiour to the IGTs 2 speed unit.

Are the differentials a new design for the OFNA GTPII or the same as the GTP I ??

It looks like Ofna is going to license different bodies. That is the back order holdup.
I had my first race with my Inferno GT this past Sunday. The engine was not tuned rich, and the rear diff was too stiff for the GRP's to keep the rear end planted. The IGT requires a fair amount of chassis setup tuning to perform well.
The Kyosho engine was difficult to tune, I suspect the Ofna .28 engine will be easier to tune based on other user responses.
