Tonight I was able to meet up with my 997 TT friend for some comparison runs after he received his car back from the dealer.

The results were dramatically improved from this weekend when I couldn't pull him at all and we were neck and neck during the runs.

This time we started from 40 mph and I instantly walked him and kept putting car lengths on him until I decided to let off. We rinsed and repeated the process 2 more times with the same results and the second time I started at 4,500 RPMs (definitely not the traditional sweet spot for our cars).

When we pulled over he a seemed very impressed and said he never missed a shift once and nailed the RPMs perfectly for his car. He also mentioned he started at full boost each time and couldn't believe how I could pull him immediately when we would start the run.

We'll get some videos for everyone this week to help put some perspective on the difference, but it was dramatic. Of course the 997TT is no slouch at all so the gap wasn't like it was in the videos I posted against the stock M5, but they were still impressive and enough where he was clearly a few car lenghts in my rear view mirror when I decided to let off. We also didn't run as fast as we did in the video against the stock M5.

Just thought I would share. Don't worry, we will post some videos for everyone to make their own conclusions.

I continue to be very impressed with the Dinan stroker conversion and would highly recommend it to anyone!

Also, I just had to order a new set of 305mm rear tires today.

Cheers,

Darren

$40K, hmm, I would pay even $50k. Still would be cheaper than the 997 turbo and more comfortable, but I wouldnt compare the two cars. I think Darren was racing the 997 turbo to confirm that he and others with the stroker have the fastest 4 door luxury sedan available, oh did I mention is still has warranty! That alone makes it very tempting, Maybe after santa comes over I will be heading to Dinan, UNLESS gets to me first, LOL.

Sounds great Darren, cant wait to see the videos. How is torque down low from a dig? I'm curious to hear how much better that is.

avi8tir,

raced 997 turbo (auto) and the mighty GTR!

see my post, it doesn't take $40,000. all you need is aftermarket headers, pulley and straight pipes. then you can walk a 997 TT past 200 km/h and even catch a GTR by the toe!

i figure you can get and install the parts mentioned above for around $7,000 USD which is quite a reasonable deal!

I think what is most interesting is that we started from around 40 mph and I walked him instantly. We didn't have to wait until 120+ mph to pull him.

The torque down low is so instantaneous it's incredible. It feels like I'm driving a supercharged V8 when I'm in low RPM because it's so different than my non-stroked engine.

Hopefully my friend with the 997TT (Quintinnn, aka Drift King ) will share his thoughts on the run as well.

Regards,

Darren
