JCR Titanium Centre Bypass equipped 991.2 GT3 RS taking the 991.2 GT RS 1/4 mile record with a super impressive 10.80 @ 128mph

Soon to be installed will be the JCR Titanium Race Pipe followed by a return trip to the track to re-test after another chunk of weight is removed and extra power gained! Place your bets??

​​​​​​​Which bypass? Looks like you have three different options?

That is actually the second proof that long headers like Dundon give almost nothing to the performance. They crook dynos well but the real life verifies that quickly. Where is that 40WHP advantage?
The other comparison I saw was Matt's GT3 with Dundon going dead head to head with stock car.

I don't know about that, my buddies .1 3RS with long tube headers ran a 10.62@132mph, took place at Atco Raceway in NJ.

He has our Titanium Centre Bypass (non silenced)

He’s soon to install our Titanium Race Pipes prior to a return visit to the track. Will be interesting if the further weight savings and subtle bump in power translate to a faster time

Don't you know? With the Dundon it would've gone 8.9@174 mph. Totally agree. All long tube are the same.

Has this car passed the break-in period? There is some talk that the ECU hinders full performance until the break-in period is complete. I'm curious to know if times would improve after break-in.

Put my 11.6 to shame.

I will go back in better conditions and try again and report back.

My launches were terrible coz i had TC off and using LC. I have now learnt thats not the way to do it.
also 38PSI rear pressures didnt help.
