Thread: Twin Engine GTP doing insane launches on the street !

<span style="color: rgb(51, 51, 51); background-color: rgb(250, 250, 250);">

60 foot time 1.53 seconds on a dirt covered roads on cold sticky MT tires. (with a burnout on a sticky track it would be 2 tenth quicker no doubt).
0-60 mph in 2.6 seconds... it's unreal how well behaved it is yet. It is a violent acceleration but at the same time super easy to drive.
Easy low 10 second car right now on the street with little traction and still running 60% power.
I'm in love...

That thing is effin crazy

That is amazing. Looks like so much fun to have, great job on the car

Wow I can't believe what I just saw, that is a work of art and ready to embarrass cars that cost 100x as much

Thanks a lot guys really proud of the results. There is a lot of thought into this project. But it was all worth it

I'm thinking more Veyron right now 0-100 mph. The Veyron would have the edge but soon this car will be quicker then even a Veyron.

Yeah, that's already much faster than the average porsche, but I'm just alluding to the amount of people whose jaws would drop on a daily basis. The look on peoples faces when you absolutely embarrass them in a gtp would be great

That's what I was leaning more towards.

Or an Agera

I would take it to a dealer and be like, there is a weird noise in the trunk.

It would be very interesting to see what the dual engine Grand Prix does on the drag strip!

That's not bad, it wasn't turbo, that's the difference. It will be at a dragstrip soon enough. We are changing the rear trans right now. trying to finish today.

I will be doing 2nd gear launches so I'll lose a little off the line but I hope the trans stays alive. I'm using the parts car trans that has around 100 passes at high power level. Not a virgin trans to say the least, I just hope it still has some life left.

LOL we were discussing exactly this. Going to GM dealer and ask for an oil change on both engines lol...

They probably won't even touch it if they see the rear engine, it will give the techs a good laugh.
