i wouldnt doubt fuel issues at all in the upper bands ---see my battle with the fuel pump x 2 yrs--i have warned several that the pumps capacity is very much at risk--with no warnings beforehand.
it is one of the reasons i try not to go over 8K in the car. we are operating at 100% duty cycle.
it seems the 09's pump is better and as soon as mazmart cant get it inventoried i will have one. They have made several changes.
i do need a fuel pressure gauge----sigh

Joff, I just sent you the file

“I went over to Juan's house yesterday morning, and spent all of the morning and most of an afternoon listening to testosterone reducing Smooth Jazz 94.1FM. Fortunately we were also installing some headers, some bigger fuel injectors, a bigger crank pulley, and some engine bay bling which sort of helped balance out the testosterone levels a little bit. (Juan's the man, don't let his taste in music fool you)”

Keep making fun of my garage ambiance music cuz I have an outfit for you to wear after I smoke your car on the 13th at Moroso.

 

hahahahah! Your images are becoming more and more disturbing

It's on like donkey kong, beeeeotch. Hopefully we won't break an axle.

 

Another idea that were going to incorperate is the ability to add another set of coolers in that are kinda humping the original set with moduler ducting. The idea is get as much cooling area out of the hot zone as possible. Especialy in places like Arizona. You do have a good point of how hot the pavment gets but since you have alot more surface area and the heat is channled in the front and out the bottom at even the slightest foward motion im sure its gona help alot.

 

I aggree I m still having problems with startups a gas stations, I can only derive that it has to do with the fuel pimp...

 

That's the only time my car stalls as well. It doesn't do it every time I get gas, but often enough to be noticed.

 

yup thats exactly what happens and I premix everyother time I visit a gas station and those are the only times it happens so I definately think it has to do with the fuel pump...

 

Folks, have you ever try using good old Marvel Mystery Oil? I use it on all my cars with no issues whatsoever. When I removed the fuel pump at 33k the screener looked cleaned.

I ran the last quarter mile pass at Moroso, the last autocross run last month and last night log with the low fuel yellow indicator light on without noticing any fuel starvation issues.

 

I've used MMO in every car I have ever owned including this one. My car now has over 100k, at least 25 of which have been boosted. No fueling issues whatsoever. Put a quart in the crankcase during an oil change and one in a full fuel tank every month or two.

you mean that atf + kerosene stuff---lol. Yep that is what I have started using for the last couple months or so. I even dropped some in the tranny Believe it or not --it helped with the noise.

Ok--need advice----has anyone pulled a lower intake without pulling the engine?
I havent done it yet--but the way I see it--it should not be a real problem. Just will have to remove passenger motor mount and lossen the drivers side + all the usual stuff?
My super duper, custom, one of a kind, purty, lighter and atomic powered lower intake is ready to go on and I have a REAL phenolic gasket for it. Plus I have made a custom heat shield between the exhaust header and the intake.
I am even thinking of removing the steel lining inside the exhaust header to increase the internal diameters some.
I dont think this is going to affect my tune any---not really. The volumne of flow may be increased slightly due to smoothing out the inside of the intake runners , but this is post maf and I dont think it will be THAT much of a change. WIll watch carefully however.
Advice on the swap?

Yes, take lots of pictures.

Also, I ported/polished my intake and polished the entrance of my Pettit intake last week. Give it a try as it might help also. Sorry no pics.

 

smarty--now i can take LOTS of pics--hope i can rememebr how I posted the last bunch

Denny, try reading this its as easy as pie https://www.rx8club.com/rx-8-parts-sale-wanted-44/how-post-pictures-updated-june-2015-a-164860/,,, I use Imagehost.org.

 

Off to the track to watch Bill in his champ car. Man this is gona be fun.

 

Take pictures and videos if you can.

 

I don''t seem to have much an overheating problem while moving (unless I push it hard) so what I have is close to adequate for highway driving. Unfortunately I have to get to the highways and that is stop and go driving that kills me for overheating. Shutting down the air conditioner and blasting the heater is not something I enjoy doing when it's 117+ out there.

Now we have done several things to the complete system this winter and the problem may not return but I am pessimistic with the heating problems of this car. The pan coolers may be viable to pass some of the heat off. Let's see what happens this summer.

 

Ill tell you what, ill build the first 4 core unit and have you test it. How does that sound?? Call Cam jr and ask him to order the plastic pan. I have 1 order sofar but that pans for Greg and im sure itl cover 105 temps seen on the east coast. Yours will probly get tied into 2 different locations.

 

Moon Phil may need an extra fan for stop and go--since he is in a extreme demand area?
with 4 coolers he will have a little extra coolant volumne also and a timer delay may be good to address parked heat soak issues? Just brainstorming here.
He may also need the 180degree thermostat set up?
If nothing else he can strap 2 bags of minute market ice on top of the coolers!!

On an AT - i would go with putting the extra rad. where the 2nd oil cooler goes on an MT and stick a fan behind it for for hot climates/heavy traffic .
I have that setup (less the fan) and no cooling issues whatsoever on my 6MT .....

 

I hope you put a real tranny cooler there phil. Think about it, the stocker gets as hot as your rad and if your engine overheats so does the tranny fluid.

 

thats a nice idea Brettus...

 

I need to see what is going to happen with the changes that are already made. If they do not work then it's time for radical changes. Some of my knee jerk experiments with other problems were not necessary and if I had just held off a little longer I would have saved both money and time. They say that when you get old you get more patient.......not me. My complaining here was out of my pessimism with the past heating problems. As summer approaches (quickly here) I will know and then I may be PMing you.

 

Bad News…Good News

I little bird (well more like a Dodo Bird) just informed me that someone is having issues with clutch slippage after upgrading his Pettit SC and increase of whp. Not to worry fellow Pettit SC owner cuz it is Juan to the rescue. Just get a new Exedy Stage 1 plus an aluminum flywheel and we can hook the brother up, yo.

The good news you wonder…

Well let’s say I just upgraded my garage totally obsolete tiny radio to a one of a kind mega blast dream come true ultra ghey smooth jazz music radio 80’s boomboxes garage wall. The clutch/flywheel swap should take @ 4 hours give or take how much you bitch about my music selection.
