Well considering Todd K. built your car and Alex's, if I had to venture to guess... I think Alex's car is probably putting out a REAL 11-1200 horse at full boost. Considering his car purportedly runs 9's, that's probably more than 600hp could compete with, even for the mighty RT12.

 

OK I confess, I have 705HP at 1.1 bar on the engine dyno not 600 and y weight being what it is, I doubt Alex is faster than me.

In all honesty I doubt that Alex D's car is putting more than 900-950HP for the duration of a quick run, regardless of the boost, but I might be wrong. Todd K. has only dyno'ed the 860+ reading on his engine dyno, the rest is more of hearsay, speculation and/or chassis dyno readings if I recall correctly. We have yet to see a time slip and trap speeds will tell us more, should be in the high 150s to 160mph.

I am confident an RT12 with 650 hp will not be too far off (from the EVOMS) in a 0-300km/h run.

Congrats on the M5, it is an amazing car.

 

HOLY ****!!

 

I hear you on that. I know throwing power at a GT2 is a different prospect and of course a dangerous one As great as the suspension is on the GT2 it'll be neat to see where you go with that...

 

I'm considering an M5. . .can you elaborate on why I perhaps should not?

 

If you take this statement "6-8 second runs" this may make this one of the fastest cars in the world. The graphs clearly shows 40 MPH to 170 MPH. If we are doing this in 6 seconds, that would be unbelievable

 

Todd, 40mph-170mph speed on your dyno compared to speed in real life? I must have misunderstood your analogy.

Was it 10 seconds dyno run? 600RPM/s X 10sec = 6,000RPMs, did your run travel more than 6000RPMs? Or you will tell me that you do 300RPM/s runs, because that is not what I have seen on the 8 second GT 750 dyno video.

It would be nice to show AFRs, boost and BSAC logs on your dyno charts instead of speed.

You build great cars, too bad to see this kind of measuring standards used for HP claims.

 

Hmm...You mean this sounds the same that most 600-750hp BMW's in Scandinavia are faster (street cars and 1/4mile for example) than those 700-800rwhp BMW's in the States.
But I'm not try to insult any tuners, I'm a happy and satisfied customer of EVO...hope Nate can ship my package soon!

 

The graphs and the details of this project here were never intended to be public information until the project was completed. That run was actually from ~2000-7500 rpms. I have complete data logs from that run as well as our other projects that log timing, O2 volts, AFR, boost, rpm, load, fuel trim, injector pulse (ms) fuel pressure, EGT's, coolant temps, knock activity, oil temps, MAF volts, intake temps etc.

The dyno testing that we do in our facility is only a small portion of the testing that we do. The videos of different dyno runs that are posted on our site are maybe 1/10 of the actual testing that goes on. We do perform high load testing on a loaded 4wd dyno for extended runs at close intervals. Typically the dyno tests that we perform on our dyno are to check consistency between cars and NOT for tuning purposes. When we build a specific tuning package, i.e. GT750 or any of our GT systems, we build a car for testing prior to selling the system. That car goes through various different phases of development, testing, tuning, 4wd loaded dyno testing, real world testing conditions, high heat testing, 2wd dyno testing and so on. As you can now, see there is far more that goes on behind the scenes than that “8 second� run that is on our site. As a matter of fact, I have to thank you for pointing this out to me because what goes on behind the scenes is probably far more interesting than the "8 second" clip of the final test/consistency check prior to the cars completion. I will have to create a video of the various segments of the testing / building process for a better insight to how we get to that “8 second� run.

 

You are welcome Todd

I will gladly pay for one of your engines or cars to be shipped back and forth to Germany for a MAHA dyno run at Manthey and RS Tuning engine dyno, just to see how it compares to Porsche HP out of curiosity

I will soon be running against one of your GT950s hopefully and will report back with a video. (been trying without success so far )

Happy New year to all.

 

Thank you for the offer, I will be bringing it there myself sometime in 2006. With all things equal, I know what Porsche HP is like, I test these cars stock to get the baseline power figures on both a 2wd and awd loaded dyno. Not sure who you are running with a GT950 but we have only built a GT800 for the customer who I think you are talking about. Enjoy the New Year.

 

Todd it is someone who has airfreighted his engine to you back and forth a couple of times at least and who claims to have the GT900 or 950 version from EVOMS. In fact he is your dealer in the region.

If it is a GT800 with trap speeds in the 130s, then I will have to give myself some weight penalty to make it fair ...Darn, same as that poor 840hp 9FF !

Just joking, good to have had this discussion with you.
Best

 

I think it's a great car. However it seems BMW has secretly given North America a SMG 'Launch Control' feature unlike the rest of the world's. Instead of launching the car at 4500 rpms it launches at 1800 or so. Makes for a slower go if that matters to you. You may never want/need that feature.
Other issues are VANOS and oil leakage, transmission failure and HUD (head up display) problems (delay in transmission of info)
I would think these issues will be resolved for '07, and by then you will have a choice between the SMG or manual.

 

Very Impressive !!!

 

I know that Todd's was the GT800 at the shoot out and even in Vegas (high up and with poor conditions for that sort of thing) with 100 degree temps it trapped 140mph.. The 1/4 mile is all about the launch but with 140 traps compared to my 135-138 if he brought his car to the same track I'm _guessing_ he'd be trapping 144 or so. That's a darn fast car at that point
