Was this the same guy who posted a GT2 racing a 1000cc bike and claimed that the bike was really racing him? Anyone remember?

Dont know why this is even an argument. Given equal power or thereabouts the much lighter car will almost always win a straightline pull unless something goes wrong with the much lighter car. Basic premise of racing. Weight is your enemy regardless of gearbox, computers or game controller you use Im partial to the one with the triangle and L2 buttons though

Nobody is saying that the GT2 wouldn't have won but the GTR wasn't racing, just as that bike wasn't racing in the other thread. I mean what fool would think that they could leave a 1000cc bike for dead without a bit of a fight?


If the R35 P800 can beat a 725hp ZR1 whilst carrying an extra passenger the (camera man), it sure as hell isn't going to get completely walked just by an extra 75hp. The lack of the passenger would probably make up for the weight delta between a ZR1 and a GT2. The GTR nearly always takes off faster than other cars at the start of races, which is why it strikes me as odd that this GT2 instantly pulled out 50 yards. If you like I can post a video of me destroying a car on a push-bike. Without the beeps, how does the other car know there's a race on? Reminds me of the old ricer fly-bys.

In short a P800 GT2 beats a P800 GTR but not by that much. Here's a P800 GTR that's actually racing:

The GTR made low 700awhp and the LPE ZR1 made 600rwhp!

David SPI GT2 made 700rwhp

The GT-R owner confirm that Switzer 997tt tip 750hp/+600awhp ran 0-200km/h as quick his car plus both cars ran 1/4 mile in 10.4sec.

Many vids between Switzer GT-R P800/+700awhp and Switzer tip 997tt p750/+600awhp and they r beating each other.

You can't compare that SPI GT2 p800/+700rwhp which made same power on less boost and lighter weight with Switzer GT-R

Yes the GTR was racing, but there is a 700 lb weight difference on top of the fact that the GTR was slightly 'detuned' by about 50hp for the street and not running the peak awhp number that it dyno'd earlier. From a dig it would be a different story. But like we always see on roll races, a slight jump also makes a big difference.

The GT2 is 200+lbs lighter than a ZR1 and 700+lbs lighter than this SPI GTR. Added to that it makes about 100rwhp more than both of them and you dont see why this race happened the way it did from a roll??????And why the race with the ZR1 is irrelevant to this race????There is nothing that GTR can do against those odds and that race, imho, is pretty much the way it would go all of the time all things being equal.

GTR needs to make alot more hp to the wheels than a GT2 of this calibur to even make it a race....from a roll. I love the GTR too man but come on in a straight line against these kinds of cars it doesnt shine as brilliantly as it would against them on a roadcourse. Its just the way it is. Because of its weight it will have that handicap hp for hp and the races will look like this one.

You can't compare that SPI GT2 p800/+700rwhp which made same power on less boost and lighter weight with Switzer GT-R

BTW...Switzer GT-R ran 6.8sec on 1.45bar and SPI GT2 ran 60-130 in 6.0sec on 1.3bar!!!

The P800 had a boost leak prior to that run with the ZR1. As you'll see from previous races with the ZR1, the P800 is much faster in that last one and still wasn't running full boost, hence only 750hp (crank).

The Switzer P700 runs 6.9s 60-130mph, the P800 is around 6s dead.

See post #62 - 5.6s for 60-125mph for P800. Also see #72 before fielding a question on the fuel and making me waste another post.

And the P800 makes the same whp as the SPI800 GT2

A P800 on race gas is as follows:

Looking at post #10, the race starts in 2nd allegedly. I'm not sure an RWD car can even hook up 800hp in 2nd on street tyres. I've seen traction lost with a lot less. I don't see the GT2 making huge headway until after 130mph in a true race.

Ask Switzer himself for a re-run. He makes both packages so should also be unbiased with data.

What we always see on roll races is a 3 beep start.... except here.

The GTR driver counted the start using his hand - you can see it in the video. There is no perfect way to start a roll race. I've used a fixed sign, hand signals, 3 honks....you always have folks complaining about jumps. That's why dig racing is so much better.

Nice run....

Btw us that Gret GTR only runned 18-19.5 PSI ZR1...

Once its runned 20-21 like it regulary does on 93 pump...ZR1 lost all chances...



More to say....GTR 800 with torgues limited to 600+....runned 10.47 here...at 133+

and yesterday SPI 750 broke another record and runned 10.3 here with 3/4 tank and it it was spining all wheels cause tyres where new and didnt hook up well... We think with empty tank think 10.1-10.2 is possible !!!

All SPI cars are very FAST !!
