ColtGT4g63 Posted March 24, 2010 Author Share Posted March 24, 2010 Thanks guys! Hanns, Your car is a monster!!!! Love the wheelie pic. Eric, Can't wait to see your car back together and back on the dyno. Should put down some impressive numbers and run some impressive times.

dustin280zx Posted March 27, 2010 Share Posted March 27, 2010 In my opinion the BW s400 series turbos are the best sounding turbos. Wait until you add some more boost and really spin that turbo! Great job on your first return runs! Quote Link to comment Share on other sites More sharing options...

ColtGT4g63 Posted July 3, 2010 Author Share Posted July 3, 2010 Well not a huge update, but its something. I installed a transbrake into the car and took it out to the track again. Managed to get a best of 6.7 @ 101 with a 1.49 60ft. I don't know whats up with the MPH, but I like the E/T!!! I'm probably going to throw the car on the dyno in the near future to do a little tuning. I'm also having problems with the car leaning out at the track. Need to give that a little attention also.

yessir Posted August 18, 2010 Share Posted August 18, 2010 how much does your car weigh? Quote Link to comment Share on other sites More sharing options...
ColtGT4g63 Posted September 14, 2010 Author Share Posted September 14, 2010 No idea really. I would guess somewhere in the 25 - 2,600lb range? Quote Link to comment Share on other sites More sharing options...
Cable Posted September 14, 2010 Share Posted September 14, 2010 I just weighed my 280z (specs in sig) and it was 2700 lbs on the dot w/o me. My buddy also weighed his '73 240z at the same time and his car has similar specs (his has a 5.3) and it was right at 2620 lbs. Quote Link to comment Share on other sites More sharing options...
Cable Posted March 24, 2011 Share Posted March 24, 2011 Are you planning on ever running the exhaust out toward the back or leaving it 'as is'? Quote Link to comment Share on other sites More sharing options...
ColtGT4g63 Posted April 1, 2011 Author Share Posted April 1, 2011 (edited) Are you planning on ever running the exhaust out toward the back or leaving it 'as is'? Probably going to leave the exhaust as is. With the Auto in the car, I can't really tuck the exhaust up into the tunnel like I could with the T56. And it would probably hang extremely low. The way I've got it now seems to be the easiest solution. Edited April 1, 2011 by ColtGT4g63 Quote Link to comment Share on other sites More sharing options...
Cable Posted April 1, 2011 Share Posted April 1, 2011 That can't be quiet in the city or highway. Plus I'd worry about too much exhaust entering the car. If I ever go turbo, I would want to run the exhaust all the way out the back to my existing dual exhaust via a single 3" to dual 2.5" Y-Pipe. Do you have pics of your old down pipe where ot routed from the turbo flange back to the trans area? Lastly, how much stall you running in the TH350?

ColtGT4g63 Posted April 6, 2011 Author Share Posted April 6, 2011 (edited) Its VERY loud, and very stinky. But the car really only gets used at the race track, unless I'm driving it around tuning it. The stall is a 3500rpm, but I have been able to get it up to 4k on the trans brake. When I had the exhaust going through the turbo and my two 3" mufflers in the rear. It was extremely quiet. SO much in fact that you could hear the valve train noise over the exhaust. Edited April 6, 2011 by ColtGT4g63 Quote Link to comment Share on other sites More sharing options...
Cable Posted April 6, 2011 Share Posted April 6, 2011 I am glad you were able to keep the downpipe from going under the engine crossmember. Another question, what are the dimensions of the intercooler you used (either overall or just core measurements)? Quote Link to comment Share on other sites More sharing options...
ColtGT4g63 Posted April 7, 2011 Author Share Posted April 7, 2011 It was very tight, But ya... I melted the little plastic vent / whatever it is that sits on top of the steering rack from the exhaust being so close. My intercooler core dimensions are about 20" x 12" x 3". IAT's weren't tremendously high while I was racing, but they weren't ambient either. Quote Link to comment Share on other sites More sharing options...
Cable Posted April 8, 2011 Share Posted April 8, 2011 If I ever go turbo, I'd want the intercooler for street driving and meth injection for WOT track racing. Quote Link to comment Share on other sites More sharing options...
ColtGT4g63 Posted April 8, 2011 Author Share Posted April 8, 2011 If I ever go turbo, I'd want the intercooler for street driving and meth injection for WOT track racing. I've got a methanol kit on the car with a toggle switch to turn it on and off. And So far I haven't even used it once! Need to get on that.

Cable Posted April 8, 2011 Share Posted April 8, 2011 I've run meth before, a progressive setup (fancy Hobbs switch) from Snow Performance is the only way to fly. More or less the volume of meth being sprayed increases as the amount of boost increases, regardless of the pedal position. Quote Link to comment Share on other sites More sharing options...
ColtGT4g63 Posted April 10, 2011 Author Share Posted April 10, 2011 I have a new AEM kit that lets you set the boost pressure where you want it to come on, then the you set the max boost pressure where you want it to be spraying 100%. And it ramps it up accordingly in between. It has never seem to work right on my car though. But I've been having a few other issues which might be the problem. Hopefully I'll have the car all back together in the new few weeks and back out at the track if all goes well. Time will tell I guess.

ColtGT4g63 Posted May 25, 2011 Author Share Posted May 25, 2011 Okay I wanted to give you all a little update on the car. No more 5.3! I ended up having oil pressure problems due to bearing / journal failure. Swapped out the 5.3 for a 4.8 I found on Craigslist for 300 bucks. Slapped on my 317 heads and LS6 cam. thew it all back in the car and started boosting the hell out of it right away. I'm far from done with upping the power, but took it out to the track to test things out a little bit before going for the gold. In the near future I'll be running the car on E85 and doing a little bit of dyno tuning. All of these runs are done on pump gas, and no more then 15* of timing. And an 11:1 AFR. Enjoy!
