Yea, the motor is definitely out driving the brakes in a heart beat. There's blue chatter/heat marks on both my rotors and that's just from getting into it on the road here and there in 2nd and 3rd only to discover i got going way too fast way too quickly

I'm torn between bigger brakes and teh ability to run my slicks on 15'' rims. I need to find out what's the biggest brakes i can get that fit under a 15'' rim (i don't think the stock GSX stuff will) but i have a GSX front brake setup with slotted rotors i can get here very soon just for doing teh swap out to his new brakes, so i'm going to do it as soon as he gets teh wilwoods...sorry to go OT...back to our regularly scheduled prgram

I believe you gas mileage is good because your running real lean during cruising. Everyone I know thats ran e85 said running in the 16afr's is dangerous and can burn up a valve.

Yea, i think some one else had warned me about th esame thing. My theory is that i've ran a couple hundred miles on the interstate running as lean as 17-19:1 on pump gas and never had any issues. And as i pointed out in another thread, honda experimented with lean burn models of the accord and accord wagon that ranas lean as 22:1 on highway and during warmup after teh first 30 seconds of afterstart.

Good point, when tuning the lo throttle on the wbo2, what throttle percentage should I be at. I mean 10% throttle and 15% throttle drastically changes the wbo2 reading.

[JayRolla]

Well I got the car tuned out pretty good now, lo throttle hits 15.5 afr lowest under any load. WOT is 10.9-11.1 afr. Here is a third gear data log. Boost hits 30psi and by 7000rpms its holding 26psi.

RPM INJD KNCK TIMA
2800 14.8 0 25
3200 26.5 0 19
3600 39.8 0 18
4000 57.0 0 11
4200 57.0 4 9
4600 60.1 3 13
5000 64.0 2 15
5400 65.6 1 18
5800 65.8 0 20
6000 67.1 0 23
6400 67.9 0 22
6800 68.0 0 22

Im going to have it dynoed and then take it too the track. Im going to test this clutch and tranny setup pretty hard. I just have to wait till my fiance has our second little girl. She is due June 24th so its pretty close.

Wow those are great timing numbers. Looks like you got a pretty good tune out of it, especially at 30psi. Keep us updated with the track and dyno results.

I'd be interested in knowing about how hot the air is coming out of the charge pipe before the intercooler at this boost level. Im pretty convinced that (me personally) I will not get 400 HP at 30psi on this turbo (I have one now). Its all about efficiency. How well do RC 1200 cc injectors idle? I havent read anything (good or bad) about them.

Well I can tell you one thing. There is deffinently a difference in the "butt dyno" from 24psi to 30psi on this turbo. Tires expecially spin a lot easier at the 30psi also so it is making more power at the higher boost level. Even if the intake temp is high the e85 doesnt care, .

The injectors idle great, about the same as when I was running 550's, just likes to dip a little more when you let the revs drop. Im also still at 0* base timing so that may be the issue. I think I may get a keydriver chip soon so I can get a lot more out of it and make it better for DD.

Hey good stuff man! If you dont run a high 11 something you need to go to driver school at this point

I wonder how much air your flowing... 1200cc injectors at 68 % IDC's.
Im sure somebody can figure something out with that.. Perhaps Dsmonster lol.

Remember my altutude up here. Im hoping for low 12. Not to many people in 11's with a 16g at this altitude.

Oh yea... That sucks, you need some sea level air like I get lol.

I think a guy up in denver running 26psi on a e85 pulled an 11.9 on a 16g, but thats the fastest.

Well finally welded up a o2 bung in by downpipe. Put the stock o2 back in and took the feel from the wbo2 to the ecu off. Now the car hits 14.7 all the time while cruising. Its amazing how much easier it is to tune when the o2 is working like it should. Gas mileage is so much better now that the ecu stuck in open loop. The wbo2 signal from the aem to the ecu was out of its range. Should be hitting the dyno soon but I have a pesky boost leak at the fuel rail I need to fix.

Glen (or anyone in the know for that matter),

From where did you get the s/s 10 micron filter? I was considering the 818 but I ended up deciding on the 828 (1" longer filter element then the 818 has, 5" on the 828 vs. 4" on the 818) because of the longer filter element. I was looking around on extremepsi's website and haven't found a replacement s/s filter element...

[90laserRSfwd]

anyone on the filter element replacement?

Well fixing up some issues on the car. I have only one fan on the radiator and have to leave it running or I overheat. So im going to buy an ebay slim fan and wire both to run at all times, along with new radiator hoses and 160* TS.

I have a boost leak that starts at 15psi and leaks pretty bad. Car still holds 24psi. Im going to fix that an shim the 16g wastegate so its pretty much shut and try to get boost to spike 35+ and hold at least 28psi to redline. Also going to advance CAS back to around 5* BTDC and see where timing goes, should be around 24-25*. Since I was at 0-2* BTDC the lower rpm suffers from timing dropping to around 9*, I would like that to be a little higher. Right now I see 22* by 5500rpm than drops to about 19 after that.

After that Im going to rent a dyno and tune here out and see what she will lay down at that timing and boost. Should be about two weeks. Hopefully everything is smooth and I will test 11.1 afr against 11.5 afr and see the hp gains. If they are not much I will just tune it back. Im hoping to break 400whp on stock longblock and intake mani. Than shooting for 11's up in this altitude on a 16g and safc. Its not heard of and everyone thinks its not possible. Wish me luck.

You have more stuff on your car than I do, except that I have cams which I don't see in your profile. You should be able to break 400awhp. My dyno numbers are at about 22psi on top end, about 28 on the low end. I'm running considerably more timing on the low end that you are. I can get the boost higher than I would ever want at like 3 grand, yet it always tapers off to 22 or 23 on top.

I shimmed out my wastegate actuator slightly with 2 washers and put a big spring on it so it boosts 20 psi without a boost controller (straight to the actuator from the lower intercooler pipe), which made it taper off instead of spike but it didn't help one bit on top end. I wish I could get it to near 28psi at peak hp, I could probably get around 450awhp. I lost about 2 psi with the cams, but gained a couple lbs/min of airflow.

I'm running a stock 2g o2 housing, maybe that hurts my top end a little. Also I'm thinking that porting my compressor outlet to match my J-pipe may help a little -- who here has tried it with or without good results?

8.5:1 AFR and lots of timing. It's a street tune. My car has never been tuned on a dyno, just ran on dyno days with a bunch of other ca
