Still getting the sheets faxed over to me, but as many of you know I had a bad issue with the software on my first dyno run, and car detonated. After sending the E Manage back to Greddy, getting it back & installing it again :

Original Dynos (3 runs) (RB Exhaust, SR Motorsports Hi-Flow Cat, SR Pullies & RE Intake) :

184 whp

First Dyno (2 dyno runs) (RB Exhaust, SR Motorsports Hi-Flow Cat, SR Pullies, Greddy Turbo Kit) :

229.4 whp

Found out that my Greddy boost gauge was off. I was only boosting around 4 psi across the board. My mechanic then made some adjustments to the turbo actuator.

Second Dyno (2 dyno runs) (RB Exhaust, SR Motorsports Hi-Flow Cat, SR Pullies, Greddy Turbo Kit) :

236.5 whp

Now my kit is boosting at 6 psi, with a 4 psi at peak. We could have turned it up another pound per specs, but the dyno was going haywire when we went back, so they had to order another part (some magnet or something).

I've ordered a few extra parts, & I will be installing them & getting another baseline (hopefully at spec which is 7 psi rev range, w/ 5 at peak) & after my other goodies.

Just thought people would like to know. This kit is not exactly bolt on. These dynos were across different times so take it as an approximation

 

nice numbers if you aren't even at the set boost level yet. can't wait to see what numbers you put down when everythign is working the way it is supposed to.

edit: oh yea what other parts did you order?

 

Water IC Sprayer, Apexi Boost Controller, Greddy E Manage Software, Larger Fuel injectors. I want to go up to 9 psi & have minimum driveability issues. Of course my car is already is already lighter...in the wallet area....sigh.

 

fanman, hows does the intercooler fit? I would think the oil coolers would get in the way. Seems like the plugs didn't make much of difference comparing to other dynoed greddy powerd cars...

 

Intercooler fits well, but lower than I thought. I originally thought it would go higher and fit flush with the front grill, but it sit lower to where the top part of the IC is where the bottom of the grill is, the middle of the IC is intersected by the strip of plastic between the grill & lower opening, and the bottom of the IC is open to the cold air from the bottom opening of our bumper. The oil coolers are on the right of left side of the the center grill so they are unaffected by the IC. One thing I did ave to do is shave off some plastic from the rear of the bumper as the IC piping doesn't fit with it, and made the bumper bulge out. Not a biggie.

Thanks for the plugs. They would not add hp. Theya re to prevent detonation. I'm sure they will make a difference for the longevity of my car. My car runs fine now that I have gotten the upgraded map from Greddy. it seems they have richened the A/F up quite a bit so no signs of detonation at all. I'm sure the plugs will help me once I start trying to turn up the boost.

 

was this a dynojet machine? Corrected (SAE) power, or Measured?

 

It is a dynojet. I believe it is measured. My first time it was 184 whp SAE corrected.

 

Here are few pics Of my install (hope they show up) :

The IC sure shows. Can you paint it? Looks like you will have a great 8 after all the mods.

 

Yeah, I think I am going to put the license plate back up as it usually goes on the top part part of the grill so it will not hinder the airflow into the IC at all. But I might eventually get a MS front end to really open up the space in front of the IC down the road. Even though I loike the look of the stock front better.

 

leave it stock..hehe no one would suspect your 8 for having a tc...well until they hear the blow off valve and you fly by them:D

 

Can you scan the dyno sheets? I'd like to see the before/after difference and the area under the curve vs rpm.
Also, any chance you could post a couple pictures of the vacuum hose connections, I can't really tell from that engine bay pic.

 

Don't worry about that grill opening there is plenty of pressure in front of the radiator to where it will not make any difference. The way the airflow works is pressure delta in front to behind the radiators. That's plural as they are both radiators. You might want to paint it flat black, that will help the cooling. Remember they paint radiators that way for a reason.

The SR 71 has a reason for being black. Kelly Johnson didn't want the extra weight but was convinced by Ben Rich that it would take 30f off the surface.
It might be another number that one came up in my mind so don't quote it.
Point is that it works, every little bit helps.

 

^^ HMM interesting. so Painting it won't be bad for heat disapating? it actually helps (if it's black) i didn't know that. then how come so amny intercoolers (most to my knowledge) don't come painted black...hehe they are probable trying to save a buck on paint...those bums:p


that's the first i ever heard of the sr-71 being painted black so shave off a few deg's ...i woudl hope it woudl be more than 30 since teh outside hull of the plane gets to be very very very hot 30 deg wouldn't make a difference at all......except in adding unneeded weight. i thought it was black due to the fact it flew so high up that from the ground it would blend in to observers who might actually be lucky enough to spot it(seeming how it cruises at the edge of space) as it flys around at ~3000 mph......but i guess you really do learn something new every day:D

 

I'm still playing catch-up on the mods before going FI, so all of your experiences will help me and others that will one day follow. My hats off to you Fred and all of the other boosted 8's.

I think they do not paint it so guys can show off by making it obvious.

The Sr 71 top speed is still classified but officially it is Mach 3.5 or aprox 2400 mph.

Did you ever see some guy who polished the top and bottom brass tanks on his radiator. Well it's a good thing it's a show car because he lost some heat rejection. Not enough to overheat but noticeable.

I'm not about to do it now but if sometime I'm looking at Ben Rich's book it's in there. I'll make a mental note to look it up. The temp drop that is. It should be more since the skin can get up to 900f. Maybe more at the tail. I know they had a hell of a time with the cockpit glass. They say if the airconditioning fails the pilot will be well done in a few min. Medium rare in less.

You know how when you wear black in the sun it is hoter than white? It works the other way also.

 

I would suggest flat black. Glosses are not as effective.

CRH

 

isnt there a new kind of paint for this application now? I could swear I heard of it recently. I'll have to check.

 

So people want to paint their ICs so they lose efficiency? Painting your IC will reduce the amount of heat trasfered to the air blowing through it, thus, keeping your intake charge 'warmer'

That's a bad thing.

 

I bet the real top speed is well beyond Mach 3.5. What was the top speed for the Mig 29 again? F-14? The amazing this is that the SR-71 and F-14 were designed so long ago, but their technology still wows us. Just imagine the stuff in the government skunkworks now...

Are you sure about the black paint... both on the SR-71 and the intercooler?

 

Don't paint your IC - bad idea.



PS: If everyone wants to experience the SR-71, buy the book Sled Driver by Brain Shul.

 

Do I need anymore proof but that all radiators are flat black???????
That is many gazillion parts that are wrong if you should not paint it to reject heat.
You should have learned that in high school physics.
Now anodizing is different, it will retain heat. Wanna know how I know. Check it with a multimeter, if it blocks electrics it will block heat. That takes university materials course to learn that one. Or you get to learn it for free here on the Rx8 forum.

Nothing compares to the SR as even fighters that go mach 2.3-2.4 that seems to be the top end of anything Aluminum. And I think they have SS leading edges.

Skunk works had to develop Titainium as a usable medium. Up till then the stuff was an oddity. Funny thing was the sorce was Russia, they had to develop fake companys all over the world to buy the stuff. The Russians might not like selling us something that will overfly them as a spyplane.

On occasion the nose will melt and distort on the SR 71. They just heat it with a tourch and bend it back. That is Ti imagine what would happen to aluminum? It would disapper long before top speed.

 

I agree with this guy:

 

You're not supposed to paint it on with a brush!!!!
Just a light coat of flat black spray. You're not worried about a showcar finish, so don't be going back and forth. Just to get thr color on it.
