Running higher than 93 in your stock engine won’t make it faster.

I don’t know what the 0-60 time is for the DeMan 4.5, but it’s gotta be better than stock.

Maybe this video will help if you haven’t seen it.

Listening to all of Matt's recent discussion about his car makes me want to ship mine to SoCal and enjoy it now, rather than waiting for the longggggggg Midwest winter to pass

@JAhmed you should definitely ship it out! I have a space open behind my Spyder at the moment since I am down to one car at the moment. Close to the airport too. I am like a mile west of Matts garage. Plus lots of national Porsche events coming up in California this year.

Hey man! Your offer is super generous and I will definitely mull it over. Looking forward to seeing all you guys again at Rennsport at the latest.

Great VDO from Matt! He states that he needed to bring the power up to the level of the chassis. While that specifically may be true (ie that the chassis can handle more...) Im not sure that with 565/440 HP/TQ that his car is not now overpowering the OEM suspension components and brakes. Even the RS with less HP/TQ has some significant upgrades in that department. I think Matt wanted a cobra like hot road roadster (and to be 'comfy') - and he definitely got that! I am in awe of this motor though and would jump on it if I thought it would improve MY experience in my GT4.

Wow Matt's car is pretty perfect. Probably drives as good as cgt. Just doesn't have exotic looks of cgt or 458 speciale. He loves z06 too so would like him compare those 2

Carrera GT has carbon tub and double-wishbones at all 4 corners and 5.7L V10 engine derived from Formula One and best manual gearbox ever. I'm sure Matt's Sypder is nice, but let's keep our feet on the ground

If you've ever heard a CGT rev its engine (and how it falls to idle instantly), you wouldn't mistake it for any Flat-6...

...man I miss my 80s-90s Dubs/Audis.

yes i drove one when they were new. local dealer had driving event at airport to convince customers buy one!

I dont even think Matt would say its perfect (but perhaps perfect for him). What you do get is a damn fun car that probably cant be replicated easily for the full price which is about $175... Its a modern, comfy, mid-engine cobra/roadster/hot rod. Doing nothing to the handling/brakes makes the car less appealing to me for canyon duties, because now youll be stomping on the brakes more often and sooner to turn at the same speeds the original car can. IMO thats not so much fun. The fun of this car is just really stomping on the gas! So a modestly similar or slightly better driver in a canyon run with a tuned or dialed in suspension will still be much quicker around the canyons than this car. I think @JAhmed did it right by adding in a full suspension redo with the 4.5L. The old adage stands - power last IMO. Still love the 4.5L tho.

I could really go for the 2 through 5 gear set...

JAhmed

Do it, it really changes the car quite a bit

Do the motor while the trans is out also.

@Rick DeMan have you been looking at the GT4RS yet? What can you do to those?

dnimi123

He did a 991.2 GT3 I think... so practically the same thing and put it up to 4.5L

I'm keeping my 718 engine stock to appease the emissions gods, but the first order of business after it was shipped to me was I got it up to Rick to drop in 2-5 ratios and an LSD. 10/10, highly recommend. Here's what they look like out at Lime Rock (wish I had a track day with stock ratios to compare directly):
