If he's blowing out gaskets he prolly has a fuel injector leak or running very rich. My 2cents.

 

Ahem













I still have to shoot the headlights and fix one moulding as it was lifting for some reason.

 

Awesome! Thanks J! Yeah come to think of it he turned the safc all the way to rich before he drove it last to go road tune it. I'll tell him he needs to turn it down. What's ideal A/F's at idle?

 

Ian those are looking good!

 

Thanks for the info guys, i got the tps dialed in yesterday and the idle set at 750 solid. Its running around 11:1 afr's at idle, should i be getting it more towards 14s or 15s?

 

11:1 sounds good to me. Usually NAs run a lil closer to the 12:1 range at idle but I dont think it will be too bad a tad richer. If you want, slowly lean it out in small inciments like .2 or .3 AFR at a time until it starts to hunt then add more fuel (thinking .5 sounds like a good number).

 

My a/f's are around 14 at idle. There isn't load on the engine so I wouldn't think it should need that much fuel? I'm not sure though. 11.1 is what you want to shoot for under boost.

 

yeah props Ian , those look real smooth!

ill work on finding a hood, LMK if you come across one

 

what kind of hood are you looking for?

 

T2, preferably not all fucked up. Fucked up as in dented to hell.

Just got off phone with Blade. He says he will sell you a hood for 150 E. Its the one off his T2 so its already straight. Easy as pie. AND (somewhat best part) its already jammed white so good stuff all around.

 

11:1 is too rich.

You'll foul your plugs and I found it causes excessive heat (un-burnt fuel in the manifold burning off).

13's are good target - if you get can 14 on a rotary that's pretty damn good and very few can (I wasn't able to with 850cc but I think it had to do with my spray pattern/seatting of the injectors).

I'm moving to 550cc top feed primaries primarily due to the seating of the injectors.

There a are a few things to getting a good running rotary.

1.) Vacuum leaks
2.) Fuel injector seating
3.) AFR
4.) TPS
5.) Timming
6.)BAC/ICS


If you can verify/get those set you should be fine.

Once you get into transients that's a different ball game but for a stock computer get those setup right and your on your way to a fun car.

 

It's not "Who let the dogs out" but "Who led the human in" LOL

My favorite quote

".....but it had a hankerchief around it's neck......"
-DogBite

This is of course while he's holding an oily rag around his wrist to stop the bleeding from the dog bite........

 

which he found from only who knows where from under the hood of his TII..haha!

 

"What kind of guy just hangs out at a park and takes a nap in the front of his car and lets his dog bite people?"

I still remember that, crazy times.

 

lol yeah that sucked...
So i got the afr's set at idle and cruising but every time i go wot it gets really lean around 5k. Im losing my mind with this thing

 

do i need to transport it? or are u close enough to grab it from him?

 

He looks nice too Brian, go ahead and scratch behind his ear...

 

LOL well the next meet will have to be where there are no dogs so Brian will be safe.

Did anyone think of a date that would work?

 

lets wait till we know its warm for sure. What town are we doing this time?

last two were Washington and QC right?

 

Not saying this to help me or Blade, but what about here in Dubuque? That way it's about the same distance for the QC guys and the Marion/Cedar Rapids guys so we don't have any fighting over place this time? :P We could do something like maybe Red Robin or BWW?

 

Hey guys! Long time no post. If you're interested, a friend from the V8 RX7 forum has a group buy going on right now. Check it out.

Holy ****. Who are you? lol Does he fabricate them himself cause if he did I could get him one to duplicate for a subaru and that would just be awesome!

I don't really care where it's at. My car will make it any where.

If it's in Dubuque just keep me away from the GTP that raced Blade, I don't want no part of that ****! lol

 

I am hosting Seven Not Stock this year. All the V-8 guys will be in town August 13th, 14th and 15th. Drag racing on Friday night, car show and dinner Saturday and SCCA at the iWi on Sunday. Hope you guys can make it out!

If you roll into the throttle does it do this?

You're talking about stomping on it about 5k?

If you're stopping on it - it's most likely due to the rapid increase in air.

This initial flow of air causes the fuel dropplets to stick to the side walls and the stock computer is not expecting it because it has two sets of butterflies to slow the inrush (primary and secondary butterflies).

After market EMS can accomidate for this but the OEM computer can't be changed from stock.

They use the TPS to add extra fuel (the electronic signal beats the air flow so it can increase the fuel before the engine even sees the inrush of extra air).

You should retain the double throttle if you don't want this problem if you are indeed experiencing the lean condition on a WOT stomp.

 

Yes it does it rolling into the throttle.

What I was seeing when we were doing a little road tuning on the SAFC is that the afr's were staying pretty decent up til about 4.4k it would start leaning out going from 12's-13's-14's and so on. So we added as much fuel as the safc would allow and it was still to lean up top.

The only thing I can think of is that with the front mount and hybrid turbo they are flowing too much air so that the 550cc primaries/720cc secondaries combo can't provide enough fuel for it.

Another thing I was thinking was maybe a post maf boost leak? Although if it was a boost leak wouldn't it run rich? I'm kind of stumped on this too.
