Hes gotta have at least a 3" downpipe on the car or the turbo wouldnt spool at all. He needs to run an open dump directly off the downpipe. Its amazing how much difference a GN will run off a dump instead of through the mufflers.
BTW GN's known for making huge HP numbers, my brother made 400rwhp and almost 600lb ft of torque on 23 pounds through a 57mm turbo. Saying this guy is making 700 is a bit much IMO. I do know one thing, once he learns how to drive it and can hook decent from a dig, they are one of the fastest cars from a dig youll ever see on the street.
Nice runs OP, car did well especially the last race. Im actually suprised the GN did so well against you from a roll.

I honestly never expected it to do so well from a roll either. After the motor runs, we lined up for the first nitrous race and PSM yells out the window to him, "Now we're gonna spray your ***, bitch!" and my friend gets this big grin on his face. Then he proceeds to walk me and all I could do was laugh. Now I'm gonna have to get that FAST intake on the car and fix the fuel issues so I can try it again on the 125 shot
yea thats about what I usually see them going for.. I was hoping mods would knock the value down a bit compared to the collector quality ones.. a GN is the next toy I want to buy..I might have to settle for a clone tho

Thanks, those races were a long time in the making! I'm the guy who would be out racing everything in my new car before I got it home (we lined up the LT1 and my G8 about 20 minutes after I got the G8 and it had 12 miles on it), but my friend is smarter about it and wanted to go over the car before killing it.

Seriously, nice thread! I'm starting to forward for another race thread from you guys, great quality video and full of useful info....
GN is nasty! But about the sound.... what does one expect from a V-6 and nothing like the Inline stuff out of toyota or nissan.

Thanks! We'll try to keep them coming. There definitely more races and rematches in the cards and I plan on using an entire bottle getting some good runs with PSM on the bike. We pretty much know what will happen at this point, but we've never gotten it on film.

I kind of agree with sticks and stones on this. He looks wlike he is making WAY more power than you on those vids, not equal power. I know my SRT4 with a 50mm and about the same amount of boost would have been in the 450-475 range. I cant see a way bigger turbo and 2 more cylinders only making about 50 more hp, especailly considering my SRT4 only made 375 on 21.5 psi and would have made 450 plus on 28 psi, only 6.5 pounds more.

Like was mentioned before the GN is on a conservative tune and 2.5" exhaust. Do some tweaking with the tune and upgrade to 3" exhaust or run a dump and you should be looking at 40+ hp. I didnt see it but is he still on a stock converter??

I'll grab a picture of the dyno sheet some time and post it up. Like I said, he was on 26 psi on the dyno making 510 rwhp and he said it was making 27-28 psi in these races, so I wouldn't be suprised if he was in the 550 rwhp range.
The converter isn't stock, but I think it's geared more towards the track than the street. That might be changed out at some point since he drives it alot.

My brothers friend with the 700rwhp GNX is a member of the 7/11 club, formerly known as "Western Washington Supra Slayers" club. 7/11 means they have members that run from 7 seconds to 11 seconds, and all can drive down to the local 7/11 store- or something like that.
See at least 1 or 2 of them at every carshow i go too up here. Know how to spot a fast one? look for the rear wheel studs.
Thats about the only way to tell with those things.

Like we already said, this GN is not exactly tweaked at the moment for maximum hp numbers and was probably making a bit higher than what his dyno sheet showed anyways since he was getting one to two more psi out of it on the street in these races. Don't get so hung up on the dyno numbers.
You can also see that up top in the last roll race, SRZ basically stopped the pull before they let off, which means there's a good chance that peak hp numbers are similar considering the weight was probably pretty close (passenger in the GN).
