far out looks like you're hitting full boost just before redline. i guess thats expected with a turbo that big. You gonna squirt a little shot of gas to get things spinning quicker ?

Is Sean sure its the microtech? sounds like a coilpack/sparkplug gap issues possibly? My bet is still on the microtech though haha

Coil packs are thru microtech, plugs are gapped to .6 already so yes.

Maybe getting interference from the coils being mounted so close to the injectors...........

Not sure if you have said you tried this but I had a similar issue with my car (microtech, 6 individual coil setup) played around with different plugs, gaps etc and it ended up just being the CAS. Get rid of it if you can afford it!

Yer plug gaps been played with. Haven't tried the Cas yet. Microtech replied to an email asking if it had a cam or cam gear, replied with yes, there reply to that was it could be putting the phasing of the dizzy out so play with it till it works right :-/ ---------- Post added 21-05-12 at 20:45 ---------- Quote: Originally Posted by stocker31 [View Post] That still good power id be stoked at that already lol.

Might put gas on wen the glide goes in, either that or if it's a pure lag monsta then I mite revert back to a smaller frame turbo.

If it's still manual, maybe try a smaller volume plenum. Also where i bought my coil packs i was told to mount them away from heat, i.e on the firewall or behind the dash. Could try anything i guess... CAS Removal sounds like a great idea!

M and W ignitions if all else fails Mo!! Mount the coild under the dash and run the leads through the fire wall, as far as i know its all pretty sensitive to electrical noise. Only going off what im told though, I use M and W and havent had an issue since, its all mounted in the car. 6 Coils under the center of the dash, ignition box where the ecu normally is and ecu on the trans tunnel. Sean will get it sorted though.

As soon as i took the load off the plug it would start missing again

Prob not relevant but sounds sorta similar when I had a custom grind cam in my old vl when I had a **** ton of of head work done we maxed the dizz adv out out trying to get it to run properly it helped alot but it used to idle at like 520 and used to break down if I thrashed it normal driving was ok tho

403 is a bit low on 17 hey? When you get ****ty with the microtech change out to a haltec Mate has had massive amounts of success with his haltec R33, 25/30, 35R, making 550~ on 23 and 500~ on 18 with BP98 Me personally, only had 1 microtech powered car, nothing but problems... Some original photos have not been recovered yet.

It's only being turned to 6500 rpm, still more room to lean on it but no reason to untill race season. Plus ur mate has a twin cam head flowing more air then mine. Also it's on a conservative dyno unlike alot of happy dynos! ---------- Post added 22-05-12 at 11:01 ---------- Quote: Originally Posted by caibs [View Post] track it tomorrow mo, 400 is box-friendly Car is still being tuned man. Should have it back this w.e ---------- Post added 22-05-12 at 11:53 ---------- Plus the head is a factor also, it's only a small port an baby cam
