Top [naturally aspirated] dyno & drag #s

[kmfdmk]

Rusty Tracey- 5M-GE - MT - 1985 - 143/136 - Dynojet (I think) @ Unnatural Inc. I've misplaced the slips and am not too inclined to find them as I've swapped to a 7M-GTE.

That was with a cheap cone filter, good plugs & wires, 10w-30 oil, no cat and a fart cannon exhaust (Apexi N1 style).

Just uploaded them on PB. stock configuration.

(dyno was also running ~10% off calibriation, proven. So add ~10% for actual numbers..) I'm not supposed to share this info, But I'll see if he'll let me get the graphs and post his name. Lot's off stuff that could be learned through this guy.

Need graph or I can't post it.

Those are high freakin numbers for a 5m! Woot! w40 transmission?

That's pretty awesome, I had thought about using a 4 speed tranny once but was told it would be worthless, so I scrapped that idea...

Sorry, won't post w/o the graph/slip. But good to have that info in the thread

I still got to get my ass in gear and get all the graphs/slips from the old thread up and running........ soon.....

Your missing a little bit of info you know

[supra_toy]

85 supra p-type, MT, 5mge, K&N filter, RC intake pipe, sucking air from the fender, and some unrelated suspention mods.

The 1/4 mi time slip is from Oct 2003 (the best of about 8 runs and my first and only time at the drags)
16.388 s @ 82.54 Mph for referance Car and driver lists the stock 1985 supra 1/4 mi time as 16.8 s

The dyno is from 2004 (baxter historical races July 2004) dyno pull in 4th gear to red line and then some (took forever to get there) peek power @ 5250 rpm or so.
135.45 hp & 143.91 tq

If there is anything further needed let me know. I think that I'm one of the few that has the 1/4 mi time and dyno on the same car with the same configuration

will

Ladies & Gents,

I thought I would go ahead and get a 5MGE dyno graph posted up here. I did not have a lot of time to play around with the tuning, so I am not posting up a 180-plus HP graph, but it is close...

Name: Carlos Brown
Year: 1986
Motor: 5MGE
Trans: 5-speed W-58

Given a few changes to the 5MGE motor, I believe it is capable of putting out somewhere around 190HP, or greater. The thing that I have found with the motor while tinkering with it, is that it wants to breath, and breath some more... This is easy when switching to ITB's and stand-alones, but when running the OEM ECU and AFM, it is a little more challenging. You will also notice when looking at the dyno graph that the stock fuel MAP is way rich in the lower RPM's. I adjusted the AFR at the upper RPM's using an adjustable fuel pressure regulator. At cruise speeds the car will run at stoich, so the richness is not so much a problem..

If there were a larger AFM available which could be swapped out, along with a larger throttle body, this motor would be a lot happier. I do not know the "true" specs of the RX-7 and 750 BMW AFM's, but these would be the only two options I think that might be available...

I will be staying with the single TB on my Spring rebuild, but I will be adding a few internal engine parts, stand-alone, and 7M crank. I had considered adding a 1UZ this winter, but at the current HP rating, the car is getting funner to drive... For now, here is 178.26HP and 161.12TQ for you!

Best Regards,

Carlos

Those are extremely impressive numbers! Significantly higher than most other 5mge motors.
I guess the question everyone might want to know is how? Was this with a bored out TB? Or adjusted cam timing? Head work?

Whatever the tuning, it seems to work well! You couldn't adjust the richness out on the lower rpm range? That would have probably flattened your torque curve nicely.

Good job!

DonL,

I did perform some port work on the head and the Intake runners/plenum are all gasket matched. I also polished the combustion chambers. The valves are still original, no OS.

The car is running adjustable cam gears, which makes tuning so easy.

I am also running the Rabid Chimp Intake with a modified 70mm TB and Intake. I am still currently running the AFM and stock ECU, however.

The fuel MAP can only be adjusted be increasing or decreasing the regulator PSI. So, the whole thing moves up or down. With tuning potential the low end power would have been much better.

Regards,

Carlos

Thanks Carlos! That SDS system is just crying out your name

I bet you get some impressive numbers once that standalone and motor come together.

You'll enjoy the tuning !

speaking of high hp n/a 5m's, you guys remember this?
