About time! Can't wait for 12's man.

Felt great when you saw that slip didn't it? I screamed like a school girl when I saw mine.

hahahaa, yep, so did I, even the guy that gave me the slip went holy sh*t,

[David Bohrer]

Glad to see you stick with it Dave!

You talking to me or Bryan aka Dave?

I think it's bad luck to look at your slip until you pit.

Hahaahaa, sure, whatever,

Awesome! he's back! Hope I had something to do with that

[TurboJerry]

Awesome job Simon! I am really thinking that a '89 turbo cam is the way to go now. Seems like the bigger cams don't like over 18 psi boost with the way the head is designed, and the backpressure issues. I suggest to check the timing and A/F ratio the comp is giving with a scanner while driving at WOT. Maybe have a friend look at the scanner while you drive to be "safe".

Simon, Back your ignition timing off 2 degrees and ty it. What does it take 5 minutes. Run it and see. Put RN3c's in there for plugs gapped at 25-28. They are a NON-protruding plug designed to stave off detonation.

Jerry is correct about high pressure and current cam designs. Too much overlap at high rpm boost pressures. Hopefully that will change soon.

Quick fix for you (you ARE a shop owner). Put a .020" shim on there to lower the compression ratio a tad. That WILL help with detonation. I've run one at 22 psi boost consistantly before no issues.

2.5's and swirl are just prone to detonation. You can't run a 2.2 and 2.5L the same way with a swirl. Chrysler knew it and built different spark curves in there for a reason.

Amen on all of that Ken.

Simon, I highly highly highly recommend that you hold off on the alky injection until you do these things. You are masking the real problem, and you will only make yourself further fustrated messing with alky and fuel mixtures when you can make a few simple fixes and be rest assured.

Ok, thanks.

I did try backing off timing, I managed 4 deg retard before I ran out of time.

I have the NGK recessed plugs already,

I will try playing with the timing tomorrow night. Shim is out of the question, too much work AND I like the way it drives around town, which is 99% of the time.

Frank, alky is up and running, it works unreal. I need to go smaller on the jet but I was running 25psi on 89 octane with NO DETONATION. Friggin unreal.

I am keeping and using all your idea's guys. Thanks a million. Tomorrow should be a record breaking day for me,

Dont you mean "I'll be happy with 14's" ? lol... good luck!

I too am one to expect the worst so that any thing more is a bonus. It really is a great way to go through life.

However, there are times when you just feel invincible, and know you will come out on top.

Simon, my fingers are crossed.

sweet you got alcohol, did you use a windshield washer resevoir and pump or did you use something else? does it inject before or after the turbo? i'm definately gonna try to make it out there for friday night.

I used a ShelbyZ fuel pump, relay, GM purgle solenoid, Hobbs switch and NOS nozzle, 4 litre Windshield washer fluid container. If it works, I will do a write up on it on the fab section or in the alky section.

NOT CAM.... IGNITION

[turbovanman²]

NOT CAM.... IGNITION

I tried both, retarding it 4 deg on the IGNITION side- made a teensy difference. Thats why the alky, I can't run enough pure C16 to stop it and I don't have any more time, and money to build a seperate tank for it.

[GLHSKEN]

If you are running 8^ initial and you still have detonation, SHim the head.

Nah, I like doing things the hard way,

[4cefedomni]

hey simon it looks like i will be there tomorrow and i might bring my omni out i just went to the mission website and read the rules for the street legal drags and it no longer mentions rubber fuel lines, do you know if they are allowed now? it also says no plastic oil lines so it looks as though i will have to disconnect my pressure gauge. see you tomorrow!!!

[4cefedomni]

what time should i try to get there for tech inspections?
