Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    Twin engine gtp powered custom car runs 8s

    Enjoyed many 8.6 passes @ 162 mph. Pretty consistent. Upped the boost on the last pass and ran 8.5 but backed off at 900 feet. Data says it should have been 8.3x or 8.4 low. All in all pretty happy with the car. Track was too slippery to add any more boost. That's why I backed off on the last...

    Twin gtp e engines custom car runs 9.11

    Yup trans are slipping bad, especially the rear since I can't turn down the power. Up front I limit the power to 20 psi of boost. 9.11 @ 145 mph backing off before the end (out of gear on the rev limiter because of trans/torque converter slip). Easily an 8 second car if we can get the trans to...

    First ever drifting Grand Prix ! must watch

    Just another thing the Twin engine can do with it's independant rear engine controls. Lots of fun. Things get interesting when during the spin you get in the throttle on the front engine. Going to need more practice for this !

    Twin Engine vs High powered GT-R Red Devil from Zilla Motorsports

    Very cool in car videos, you guys have to see this. Street style event, no glue, spinning the whole way to the 660. Still managed a very quick 6.31 1/8 mile ET ( high 9s equivalent in the 1/4 mile) The GTR is on four slicks same as I. We are both running time without hundreds of a second of...

    Twin engine best 1/8 mile so far 6.21 ! Street race event

    We had a crowd around the car all night. It made a huge impression. It was running times like the big slicks V8 race cars. No street cars would line up against it. We'll have to really be aggressive next time to get some races.

    9 Second 1/4 mile runs this weekend with the Twin Engine GTP !

    In the heat Sunday, 93F + Humidity ! Two bone stock engines, two stock trans. One from a GTP on from a Cadillac. 1000$ worth of drivetrain ! I was shooting for 9.4 and I added 6-7 psi of boost in the rear engine. But I overboosted off the line at 20 psi in the start line. Hurt the 4t80e...

    A ride in now 1150-1200 HP Twin Engine GTP

    Had a race with a Maverick 1000 side by side who tought he could take my stock GTP. He was dead serious lol. We said nothing. After the race, he asked me four times HOW MUCH HORSEPOWER IN THAT THING ??? lol Yes, cranked up the boost... That 4t80e cadillac trans can take it.. No slip, ran HARD...

    Twin Engine GTP new 4t80E trans setup testing at dragstrip

    back from the race... I'm uploading a video now. Wow what a frickin beast !! We know now it's a 9.6 1/4 mile car from the 1/8 number vs my last number when I ran 10.0 And that was on the very 1st try with medium boost on a slippery track. The track was just rained on in the morning so the...

    4t80E trans swap

    I'd love to see all the info in one thread but compacted. As for as fitment, all I need to know is block clearance, bolt patterns and also mods to the flexplate. Basically how to make it work on a stand. There is a very long thread about this I found and it mentions the bolt pattern is...

    Twin Engine GTP First runs at the dragstrip !

    In order to keep my trans alive, I force them to start in 2nd gear. It's easier on parts not having to shift to 2nd gear. It worked very well in the 11.0 Parts car. So I figured I do in the Twin Engine. On the street the car hooked so hard it was unreal. The little wheel spin helped launch it...
