phunk's CJM Greddy TT - Build, Info, Reviews, Etc

esfourteen

Good to see you are finally on the forums, Charles. We talked on the phone for awhile a few weeks back about your fuel return kit and the issues regarding inconsistent vacuum pressure when cruising due to the VVEL/throttle body issues. Have you had any more luck figuring out a work around for the issue?

Awesome build. Once my install is complete, we can compare notes.

Maybe we'll get the chance to meet up sometime and see the difference.

Phunk, how would I go about getting the barbed fittings out of the throttle bodies? I haven't messed with them for I didn't want to break them off in the TB's. I know they can be removed for I've seen it. Nobody was around for me to ask that day.

Nice build. That's how they should be done.

those types of barbs are a press fit. so they literally just have to be pulled out. easier said than done, but they do pull out. You have to be very careful how you load it, or you may crack the brittle cast aluminum. I usually just grab them in a vice and twist back and force to break the seal and then pull and spin.

remember one thing, there is no going back. The best you can do to add barbs again later is to tap the leftover holes and thread in fittings.

man i told you they just pull out! Pull out method = effective

Sounds like a plan Dai. Not sure I want to make that move at this time though. I will see about it once I build another motor w/ forged internals........

From the 350Z to 370Z... sick build as usual.

Do you have any dyno charts? I'd like to peek at the torque curve at different boost levels.

thanks guys. i do have my dyno charts from last week... but im trying to get back on the dyno ASAP. the midrange/torque curve is what i need to do all my work on with the ignition timing. my research is pointing to me that my current timing curve is way off target in those RPMs (due to E85 and my lack of experience with it). I wanted to get back on there this week but so far havent had time. perhaps this weekend or early next week i can.

as for the manifold vacuum holding steady under various circumstances, i havent yet done any logging with the intentions of keeping an eye on that and looking for any patterns or consistencies that would make it safe to say that we could use vacuum referenced regulators on this car. it will require supplemental logging equiptment since the stock ECU does not monitor the MAP sensor... well at least it doesnt appear that way as its not currently an option supported by my Osirus ROM. I think its just for the VVEL module but perhaps it is wired to the ECU... I dont have my service manual here to look at how its wired.

I am hoping to have time to add to my thread in the next couple days... super busy with trying to wrap up some new products.

How time flies! I am at 5700 miles since the turbo install. The car is holding up amazing and running very strong. I still daily drive it and daily cruise/abuse it. Its actually my only car at the moment. Weather has just been so great in Chicago the last few weeks, that I cannot stop to take a break from enjoying this car.

I haven't bothered to put it back on the dyno yet. Apparently my work on the tune so far was safe enough. Nothing seems to phase the engine. I have been running the boost to 8.5-9.5 psi occasionally. I have no idea what its making there... if i had to guess maybe 550-570rwhp since the car seems to make about 30hp per psi. But 75% of the time I am at just 8 psi anyway.

My 305 RE11s are about done for. I ran maybe 8000 miles out of them. That was with about 1.5* negative camber in the rear. I havent done any typical burnouts or donuts yet, but the 370 leaves intimidating patches of rubber if I floor it in 2nd or middle of 3rd, and I am guilty of doing it for no good reason other than to just admire it in the rear view mirror often enough.

Many very fast cars around Chicago have been humbled recently. Those that ask are shocked to hear the car is running less than 10psi boost on a stock engine. It seems to impress most enthusiasts, and piss off the rest.

I get into it with a few good cars a week. GT500s, SRT cars, turbo Porsches, C6 Z06s.. all the typical fast cars. Without significant mods, they can forget it. Exception, an '08 997 GT2 with minor mods gave me an even run the other day, but that's no regular turbo Porsche. The twins on the 370z really put the car into an entirely different performance category. Keeping it real, many of the "fast" cars that the twin turbo 370z can now pull on, would kill the Z should they have as significant of an upgrade. But alas, 99% of them do NOT, and good luck finding them out there.

Making a slow car fast while its still a pretty new model really does compound the entertainment value. I experienced the same thing in 2004 with my TT 350z. I can imagine that many of the enthusiasts that wanted to give me a go, probably had not been given a chance to even have at a stock 370z yet. While I do see them on the road, I have yet to find myself next to one let alone one willing to give a run. So I amuse myself thinking of the guys that were possibly excited to have their first 370z roast just to end up getting completely burned. I have a nice cocky "you like this" sticker on my 1/4 window to top off the experience.
