Nothing spectacular. Today was the first day of actualy tunning the car under its own power. I only left the dragway once and went less than 1/2 mile away before relizing my laptop batt died, and promptly went back. Never left after that however did manage some 2nd gear 5krpm (up to 10kpa) pulls in the parking lot. Should start tunning under boost this week after work

If you have no idea what car im talking about, its a s4 gxl (i think) with 13b-re, to4s, wolf3d v4 etc etc

First vid is of the car just idleing while my friend adjusting a few of the load bands in prep to go above 30kpa up to 4k rpm, i got out to check for leaks n such (hooray none!) Found out its real hard to drive the car while its un-tuned, watch the wideband, and the wolf display (car was running between 89 and 96*C) and tune, so eric actualy did the tunning today

Second and third are of some pulls to 0-10ish kpa peaking just shy of 6k rpm, half throttle (still scard of breakign things) in 2nd gear.

and before i forget, here are the video's. BTW you need a divx codec to play em, if your not sure what im talking about, or know you need it, get it here http://download.divx.com/divx/DivX521XP2K.exe

On a side note, while the engine was idling, i was pulling 57kpa, is that good (seemed good to me) and under deceleration a few times i saw 78kpa?

nice, i can smell you rotary.

 

hello jacob,

convert that kpa into inHg and we can give you a good 'yes thats good' or 'no thats bad' response

 

57kpa is 16.9inHg
78kpa is 23inHg

this is according to http://www.woodworkingathome.com/ref...conversion.htm

Where does your idle sit?

 

1100ish once it warms up

when i first started it thismorning it was a nice 1800, i was able to adjust it to 1500ish, then from there it went down as it warmed up

Does this engine have a partial bridge like your sig says?

 

Neg, thats the other rx7

 

any pics of teh port on thsi baby

 

this is a stock port 13b-re, i never opended it up

 

17" Hg is fine, 23 on decel is normal because it is drawing more air with the throttle plates closed resulting in more vacuum.

 

Man, whats your premix ratio, that thing smokes like crazy!

 

if its a stock port RE it should not be idling that rough.

 

lol, thats how my car sounds right now. Sounds like he has an exhaust leak as well...

 

Yes exhaust leak. and the smoke is oil in my exhaust.

When i first started it up and it finnaly came to life i was running it without an oil restrictor. I figured idle wouldnt make enough oil pressure to effect things.. i was wrong, lost 2qt of oil to my exhaust. So its going to smoke for a while. I have a restrictor in and now it doesnt loose any oil

It doesnt idle rought at all imho, it it ossolates less than 100rpm. Howerver, ill try to smooth it out after work
