Video is not a Dyno Jet it's a Dyno Dynamics. Not really sure what you mean by doesn't mean a whole lot but.

DynoJets can't really be altered to the extent of a Mustang and the Dyno Dynamics dyno in the video. Dyno Jet numbers are pretty much the industry standard when talking about whell HP and TQ.

To me dyno number mean **** its mealy a tuning tool. Hell my car will never even see a dyno so...

Several things.

1. AMS had a package deal on both their front mount IC and the SST cooler when purchased together

2. I liked the placement. Safe from rocks, debris etc. ( Factory replacement )

3. Held more fluid than stock plus had a shrouded fan that really really flows a crap load of air.

4. AMS quality.

5. Doesn't block other radiators.

1. Please open your eyes and watch the video again. Its 500 HP on a DYNOJET and 399 on the DYNOCOM.

2. I have seen a DYNOJET claim a Z06 vette has 505 HP to the wheels.. FAIL Then the Mustang shows 370. This is prolly more accurate.

Dynos are great tuning tools. It just cracks me up when I see wild number claims. Its all relative to the data at hand.

The torque number that a dyno creates is estimated calculation of engine torque created at the crankshaft without any losses factored in.

Particularly the EVO guys, any horror stories you'd like to share.
The answer to your question is no in regards to hp/tq related failures, not accounting for accelterated clutch wear that has been encountered, and quite rapidly in some cases.

Improper tuning can cause accelerated clutch wear/failure, however this is not catastrophic, since clutches can be replaced. Improper tuning can also cause shifting issues.

All of the SST "horror stories" have been related to failures that are totally un-related to mods or the power output of the engine. Sadly Mitsubishi still voids the warranty at the drop of a hat. That being said, there is speculation that one particulare brand of aftermarket fluid contributes to the temp sensor failures, however to my knowledge this has not been proven.


Regarding the AMS cooler, it is an upgrade from stock, but it does not provide the same cooling capacity or functionality of the SSP cooler kit with it's stand alone pump and ability to circulate transmission fluid through the cooler while the car is not running. This is important for track days with short times in between lap sessions. The SSP kit does not interfere with the OEM cooler, and in fact leaves it in place and functional.

1. The 399 is a Dyno Dynamics Dyno which DG Motors has.
Didn't see the Dynojet at the end the first time so your right there

2. Regardless what you saw or heard When people in industry talk whp and wtq DynoJets are usually consideded the standard as readings you get from one can easily be compared to others around the world.

A stock Z06 will not make 505 on a Dynojet with the factory tune.

There is something not right about this car's tune. This a road vid of that same DG Motorsports 500 WHP Evo. Look at the speedo when the guy is flooring it. You can hear the engine screaming, shifting hard, revs flying to red-line; but by 3rd gear he's only going 60mph?!?! Shoot if I floor my car, I hit 60 in second gear, and 100 in third. What is going on with this car, its actually slower after all the work they did, something is not right here...???

Actually watch real closely... the camera is shaking pretty bad. But he switches into 4th at 80 and thats right on the money for an MR. The gearing is different in an MR over a GSR. But the MR does have 6 gears as well.

The plus side of the MR is at 80 MPH cruise it turns 3100 RPM and the GSR is turning 4K

As far as the speed of that car...its got very low TQ.

You guys are a little off.

sstevojr: If you rev to 7600 rpm in your RA on stock tires, this will be what your max MPH will be for 2nd, 3rd and 4th:

2nd: 55mph
3rd: 75mph
4th: 99mph

In the MR, at 7600 they will be:

2nd: 60mph
3rd: 82mph
4th: 108mph

Supraboy:

With stock tires, the Evo MR will be hitting this RPM at 80mph in 6th:

3300 rpm

With stock tires, the Evo GSR will be hitting this RPM at 80mph in 5th:

3750 rpm

Thanks for this. However this brings up the fact that the stock RPM gauge is WAY WAY off. I just ran my car at GPS measured speed of 80 MPH with cruise on and was at 3080 RPM give or take 50. I have stock rims and tires.

A few questions/comments: Was your tachometer ever replaced after being damaged during your blue LED installs? Possible the needle was put on a few teeth off?

Your Bridgestones are .1" taller diameter than the OEM Advans.
