669whp T66bb Dyno Video

[rhombus]

I dynoed my car again about a month ago. I just now got around to making the video.

Car was dynoed @ 35psi on 100 Octane Pump Gas

The day before I had just installed a Q45 Throttlebody and 4 bar map sensor. Both of which required me to retune my maps completly.

Apparently I did not tighten down my fuel rail enough and had a boost leak around the #1 Injector during the dyno. This is what caused the dips in power.

I have also been playing with my cam timing. Peak Tq has been moved back, but I am not happy with their settings yet.

My next dyno trip will be on Cam2 gas with more timing.

Hopefully my slicks will arive sometime this year and I will go to the track.

I like how you hold you Radiator in place :) :rawk:

jeebus man, what happened to your fenderwell?
STB time ;)

stb won't clear the fuel rail, haha.

[rhombus]

actually, it might now with the new fuel rail. I need to try it again. Just havent wanted to put it on yet, cause it blocks plug access.

+10 points for still using stock catback

[driftracer]

nice run :)

[Sky240PWR]

what is your 1/4 mile times with that much hp?

[kandyflip445]

Hot shit! :eek:

LOL, good eye! Should hear it when he goes from closed cutout to open... shoots flames out the cutout, now thats badass

How long have you had this motor running that much hp? I went with cp pistons also just wanted to see how they were holding up.

There was a moth near the turbo at 4:24, the camera moved away, then when it moved back the moth was gone. I wanna see it get sucked in!!!

Well I have not been running "this" power for very long. They motor has been running since last december, so over 1.5yr. I have consistantly had it at 20psi or more the entire time. But I just recently have turned it up to 30+. It doesnt seem to mind. At 30+ psi things start to happen, like vac fittings blowing apart and such, but that is the only problems I have had, besides maxing out MAFs and Injectors. Ive gone though so many sizes of injectors its crazy. Started with 680 before I built the motor, then went to 880 and put on the T66. Those maxed out at 18psi (and so did my MAF). So I went to 1000cc and D-Jetro, those maxed out in the upper 20psi range. So I tried 1600cc, no one said they would work, but I got them to work and idle just fine. (Not without the help of PFC/FC Dataloggit software)

im not really a big hp wanting guy, but fucking shear horsepower is fucking awesome

u fucking :rawk:
props with all that mad tuning

[sepulchral]

nice fast car......

[MisfitFlesh]

right on man, im into the whole horsepower and torque deal. I started to build my bottom end for it, but i left the stock rods and everything else was replaced and balanced. I dunno why i just didnt replace the rods but i guess thats what the next tear downs for.
