WOT o2 readings??

[Monello]

Alright guys, what should we be reading at WOT?? I have an autotap now, but its kinda useless until i find out the right range for our o2s to be at wot. I am working on making this a high 12sec car by gap, so any help would be great =)

Later,
Pat

Please discuss how you plan on making it a high 12-sec car

[Roush GT]

i thought you were getting rid of the car

[mcgavinz26]

Are you talking about using the OEM O2 sensor with someting like an Autometer A/F gauge to try tuning the car? First off, everyone and anyone always talks about how useless that setup is as a guide for tuning purposes. Second, they're partially right. It is good enough to tell you when you are not getting enough fuel or too much, thats about it though. As far as fine tuning you just can't get that using those things as guides. Generally speaking though, you would want your A/F to be at the lower green lights all the way through the RPM band during WOT.

If you want high 12s... good luck and you need some real dyno time for tuning purposes. Looking at the A/F gauge won't help you much in getting to those 12s.

[Craig99SE2]

Yeah, definitely take it to a dyno that can provide you with wideband O2 readings. The stock sensor and associated meters are trash. All they do is make pretty flashing patterns to distract the driver!

Most power is generated at 13.0 to 13.5:1. DON'T go much below 13.0:1 or BAD things can happen! If you go higher, you're just wasting gas and running inneficient. BTW, I am only talking WOT here. Cruising you want it stoichiometric (14.3:1).

[Monello]

First of all, I have an autotap which provides the readings in mV for the o2's. Which is Very accurate. The only reason it wouldnt be is if i had a bad o2.

Im not discussing it, but by GAP it will either be in the Very high 12s, or Very low 13s.

Im not selling it, i realized how much work i have put into it, and would miss it too much.


And Craig, are you talking about the A/F ratio? If so, my DHP already has it set to 12- and 11.


Im asking for the mV that i should be looking for at WOT. LIke the GTP guys say .910-.930 is good for them. The Grand Prix GTs, are saying .880- .900 is good for them because its NA.

So should i be around .920?

And making a high 12sec car is easy, just need to have the time and money. Which i will have in a month to start.


Later guys,

Please tell me you have an EGT gauge to monitor exhaust temps within 6" of the exhaust port on the head ...

11 is pretty LOW!!! That cylinder must be getting hot as h*ll after extended periods of WOT!

Yeah! This is the bottleneck. Getting the engine to 375-400HP is not the problem ... getting the driveline to handle it is!

Craig...check your PM on n-body.net

Good luck. I don't see your your car making it to the 12's. After being at the track and seeing what modded GTP's can do, I am convinced that the GA is the wrong car. I saw modded GTP's running mid to low 12's all day. The slowest GP(which was NA), was running consistent 14.0-14.03 @ 94-96 mph.

[Monello]

Craig, thats how DHP did it, so no clue. I can post some Autotap logs if you want.


And KmanGT, no offence but you are TOTALLY missing the point.

My car, supercharged, with just an intake and exhaust, was making more hp then a GTP with intake and exhaust. Both cars are basically the same. Why are the grand am the wrong cars?

They are WAY lighter! With my 60fts being 2.3-2.4, every .2 off the 60 is -.4 off the 1/4. So if i got some DRs, and got a great launch, say a 1.9-2.0. That already brings my car, the way it is, to a 13.5-13.6.

Remember, when i got my 14.3 that was with full interior, and my 18inch rims, with the cheapest tires you can get, Kumhos.

I will be going to the track one of these days with DRs, and going to practice my launch til i get a 2.0. Im going to try Intenses instructions on launching.

So with a good launch my car is already a mid 13second car. Im going to be messing with the car in the next few weeks.

You guys have 0 faith in our cars, i have learned so much over at clubgp.com

My goal is High 12's, I dont care if its 12.999.

For all you supporters, THANKS, and for everyone who keeps telling me it wont happen, just keep posting that it wont happen, because it will push me more and more until it does =)

And as far as our tranny goes. Everyone keep talking about how bad it is, etc, yet THEY ARENT BREAKING?!?!? So i think we are under estimating the good ole 4t45.

[AMRAAM4]

Well, sorry to say it, but I am glad I'm not the first....but...no way you are getting to 12's. I like you Monello and am not trying to hate, but more so trying to give a reality check much like KMan was. The GA isn't hitting 12's unless you go the route of KillerQuad. I've said it before, I'll say it again, dropping time's in the 1/4 mile is exponential...the lower you go the tougher it gets to reduce the time. The jump from 15.9-14.5 is a hella lot different than a jump from 14.3 to 12.9. You run out of things to change and the variables to work with start to decrease. You gotta have some solid basic mods and good driving skills to get a 2700 lb. twin turbo'd RX7 in the 12's (it's easily obtainable with the $$ flow though)...I'm known to be pessimistic, but I don't see your GA getting there.

You prove us wrong then we'll be sure to give you props.

I suppose if you make the motor bulletproof, get some DRs, practice your launch, and punch a 150-200 shot you might reach it, but I think you'll do that once and then be looking for a rental car for awhile

[Monello]

=)

It will be done by the end of summer, and by gap it should be a low 13sec car.

[H.O. Driver]

Are you still running the 2.5 inch pulley? and how much KR are you seeing right now?

I am not missing the point. I applaud your efforts, but to even attempt to get a GA into the 12's, is not worth the money or the effort. I will agree that, if you strip out the interior(a la Killer Quad), it may be possible. The money you would spend to make a GA that quick, could be better spent on RWD V8 power. L0w 13's or high 12's from the factory, is a much better foundation on which to mod.

This I find very hard to believe. Are you sure it was a GTP?

But that lacks individualism and creativity! Why be just another one in 50,000 Z28's or Firebird? Sorry, but I prefer to be the oddball that after a run down the strip people stop and say ... Did that guy just run a 12-second run in a ... Grand ... Am ... ????

But that's just me!

I guess after all the money I spent on my car, I expected more of a return.

Monello i hope to be joining you into the 12s ive got faith you man!
