I believe it's about $45k to do the 4.5l motor build plus gearing.

Would love to see this 4.5 vs an RS with full Dundon exhaust and plenum package.

so you built a modified car thats faster than an RS on the straights, so what? If that was a decision criteria I'd have bought a Z06.

Click baity title aside, I've driven the 4.5l and it's an awesome motor, my car would already be under the knife if not for the tri-state covid-19 lockdown. It's not a GT3, it doesn't rev to 9k, an RS is still an RS and all that, but with a fat torque curve it's a whole different really hilarious experience where the traditionally under powered GT4 feels suddenly very under-tired at the rear.

I think it's a great example of what the 9A1 is capable of and what Porsche could have done with it if they wanted to. With the RSR going to 4.2l and presumably the 992 GT3rs as well, it would be great to see more yuge 6s. 9A1 bottom ends are shared between GT4 and 991.1 GT3 so I assume that 4.5L 991.1 GT3 is just as doable. The 991.1 GT3rs might only need bore and pistons .....

Thanks for your input.

I think you missed the whole point of making this video. The GT4 was just as capable of braking and cornering as fast as the GT3, the video was made to show the power and if I didn't ease up entering the brake zones and corners then the video would have been over after 1 straight.

Decision criteria would include facts like MCS (minimum corner speed) and knowing the braking system is identical from GT4 to GT3 and the MCS is the same. Those facts coupled with the drag race results you just witnessed would certainly prove to show the GT4 could have continued to drive away from the RS.

Cheers!

I made my comment based on the text of your post and the video you made to illustrate those points. Spending $50K (?) to make GT4 faster than a stock GT3 RS, Ok I am not sure result is unexpected. Perhaps you can post the lap times so we can all get the "point".

Lap times? Really?

The GT4 was on stock tires, stock brake pads, stock brake fluid, 3 point factory seat belts....
The RS had Motorsport rotors and pads, race brake fluid, race tires and full safety equipment.

I think the point is you are just an antagonist and really have nothing positive to add to this thread.

You do know this is an Internet forum, right? Discussion is the point, and some posts you will agree with and others you will absolutely not. But it was not intent to antagonize and if you took it that way, then I apologize for my poor choice of words.

Rick- The GT4 is a Gas guzzler and the tank does not hold much- with the 4.5 liter how much thirsty is it???

It's thirsty! Making that much power would certainly require more fuel, but not as much as you would think based on % of power increase. I honestly have not paid attention to the actual MPG numbers on cruise as I really don't go anywhere in these cars to notice.

Full transparency - Girodisc rotors with RaceTechnologies RE10s. SRF Brake fluid. Dunlop Sport Maxx Race 2 tires. And a Cantrell rollbar with 6 point harnesses. My best lap time in the 991.2 RS is 2:18. A more skilled driver would likely extract an additional bit of time out of the car.

It was a completely unplanned event.

And regardless of whether it's faster or not, it's a testament that the GT4 was not a regular GT4 and made me scratch my head when I couldn't walk away from him. Turned out to be a great video, regardless of the outcome and was fun.

See you next year, Rick!

I was at this event at Sebring and awew911 was not the only GT3/RS to fall prey to the straight line acceleration of this beastly Cayman, and lets not forget that was a manual GT4 vs a PDK RS. I also drove a 4.25L equipped Cayman at this event, and even that was pretty epic. Having seen Rick in action on Sebring on occasion, he most certainly was holding back in order demonstrate the straight line acceleration comparisons in this video. To those that love the Cayman platform and prefer it over the 911 (many do) it is extremely attractive to finally have a Cayman on an even playing field with the best of the street legal, naturally aspirated 911s. I'd imagine this particular subforum won't get as many of those fellows chiming in haha. Either way, major kudos

Regards,
John Gaydos

lol - anytime, anyplace, 50 laps


BTW my old time attack evo will thrash both......................................

A car modified for racing will virtually always beat/thrash a street car - this is not news
