Drax240z Posted March 10, 2006 Share Posted March 10, 2006 Yes. Well "stock 7 psi" being wastegate only, spiking to ~8psi and dropping to 4.5psi at redline I made 211rwhp and 251ft-lbs of torque. With a boost controller holding closer to 6psi to redline I made 232rwhp and 281ft-lbs. Mods: 60mmtb N42head ~8.3:1 CR 440cc/min injectors SDS EFI Medium NPR I/C 3" mandrel bent exhaust 2.5" mandrel bent DP Port matched intake Finally have a decent boost controller coming in, (Turbosmart e_boost2) since my MBC blew up... I should be able to actually hold 6-7psi through the entire rev range with that setup... I'll try to post a comprehensive comparison between boost levels once I get that going and get my car on the dyno. Quote Link to comment Share on other sites More sharing options...
Guest ON3GO Posted March 10, 2006 Share Posted March 10, 2006 okay then i did okay. made 229rwhp and 291lbs... full solid 7psi with the Profec B turned on to hold boost. tried to dyno at higher boost levels but kept getting a miss.. like i said in my other post.. mike Quote Link to comment Share on other sites More sharing options...

violacleff Posted March 10, 2006 Share Posted March 10, 2006 Hey drax, I was curious as to why you only ran 7 psi for so long. Anyways, please do post about that eboost when you get it installed. I think those things look killer. Did you get a good deal on it? Quote Link to comment Share on other sites More sharing options...
Drax240z Posted March 10, 2006 Share Posted March 10, 2006 I had issues I wanted to sort out before turning up the wick, so I sorted. Traction was allready an issue in autocross and I didn't think more power was going to make me much faster around the track. Now that I've added a quaife I might actually be able to put some more power to the ground. As for whether I got a good deal on it... well I get a good deal on everything in reality. The perks of owning a performance shop: you don't pay retail for anything! I will post up some info on the e_boost2 once I get a chance to play with it a bit. And Mike, I'm glad I am not the only one getting those numbers on low boost. I've had my numbers questioned so many times! Now at least there are 2 of us in that ballpark.

Guest ON3GO Posted March 10, 2006 Share Posted March 10, 2006 ya i thought i was real low on HP but good on torque.. guess i did pretty well. im pissed about a few things.. 1. no AFR readings.. i wouldnt be pissed if my LM1 wasnt broke. 2. no fricken print outs of my dyno sheets, wasnt allowed to even dyno but it got sneaked by .. 3. i think i could get more out of it at 7psi but really who cares. mike Quote Link to comment Share on other sites More sharing options...
nategdizzle Posted March 10, 2006 Share Posted March 10, 2006 what is the most boost a person can run with 280zxt injectors normally Quote Link to comment Share on other sites More sharing options...
z-ya Posted March 10, 2006 Share Posted March 10, 2006 Hear are dyno plots from when my Z was running stock boost and a stock T3: (see thumbnails) Hear is my latest dyno pull running 12psi with the same turbo: Quote Link to comment Share on other sites More sharing options...
Silent Posted March 10, 2006 Share Posted March 10, 2006 ugh, hmmmmmm have turbo cars layin around. this is so tempting to do. but more headache in the end. ::thinking:: good numbers for damn near stock! Quote Link to comment Share on other sites More sharing options...
zguy36 Posted March 10, 2006 Share Posted March 10, 2006 nategdizzlewhat is the most boost a person can run with 280zxt injectors normally I just swapped over to a megasquirt and the most boost I could run with the stock injectors was 15psi. Drax240zYes. Well "stock 7 psi" being wastegate only, spiking to ~8psi and dropping to 4.5psi at redline I made 211rwhp and 251ft-lbs of torque. With a boost controller holding closer to 6psi to redline I made 232rwhp and 281ft-lbs. How does a bad boost controller make you run less than stock boost? The stock wastegate diaphram won't even pull open at all at 4.5 psi making your boost controller a mute point. There has to be something else wrong with the turbo (worn, or exhaust leak, or poor tuning) that would make it not at least put out 7psi.

Garrett76Zt Posted March 10, 2006 Share Posted March 10, 2006 I'm sure its not what you're looking for but i had my 3.0 liter(not stroker) on the dyno at only 7 psi with the 60-1 and it made 280whp. . .hehehe Quote Link to comment Share on other sites More sharing options...
z-ya Posted March 10, 2006 Share Posted March 10, 2006 Hear is a dyno sheet for a car I helped build and tune: Stock L28ET block, head and cam. T3/T04E with stage 3 turbine. 13psi. 420cc/min injectors with Wolf 3D engine management. 326WHP. Quote Link to comment Share on other sites More sharing options...

racerx260 Posted May 23, 2006 Share Posted May 23, 2006 Great numbers!. I am currently building a n54 block .40 over w/ turbo pistons and a n42 head to replace my stock block turbo motor. its great to see the outcome. I should be at about 8.4 cr depending on the head gasket. What head gasket did you guys use. I don't have an intercooler yet, how much boost can i run with this setup untill i do?

ww Posted May 27, 2006 Share Posted May 27, 2006 I always thought it was the fuel pump that wouldnt allow more boost not the injectors.. No. If it could, people would be buying bigger fuel pumps not bigger injectors. It's limited by the flow rate of the injectors. You can compensate for the flow rate a little by increasing the fuel pressure, but it won't overcome the limited flow rate of the injectors when you start to hit higher boost settings.

I wouldn't run more than 10 or 12 psi without an intercooler unless you have a better than stock fuel management system. Quote Link to comment Share on other sites More sharing options...
