Here are some things to add to all this.

1. Dynojets read CRANKSHAFT horsepower numbers. So if you dyno on a Dynojet factoring in my HP for Crankshaft numbers aren't really realistic. This is from the originator of the Dynojet, not something I am making up. Search for it, I quoted the entire topic some time ago here on EVOm.

2. There are 4 EVO's that have gone 10's on a green now. Proudly I can say I had a rather large part in all of the cars. The cars were:

Curt Brown, 10.5x at 128, our shortblock and I tuned the car.
Tony and Tom Powell, 10.87 at 128 mph, 99% BR parts.
Me, 10.89 at 128 mph, complete BR build, I tuned it.
Bobby Koenig, 10.92 at 130 mph, bunch of BR parts, I tuned it.

I also have a handful of guys that are running 11.1's and 11.2's. I expect to see more of them hitting 10's next year.

Curt's car was the lightest of the bunch and the quickest. On the other hand Bobby's car is the heaviest and yet it had the highest MPH of the entire group. I attribute this to a lot of aero work on his car and his rediculously fast shifting.

Running 10's on a green is possible but it is a tough task.

 

Somebody fill us in on the "aero mods".

 

One thing for sure. The Green/20G-LT is exactly what the factory would have done, if it wanted to up the ante, using the current platform. I've driven the stock IX turbo as well as the Green in many spirited sessions. I honestly can't tell the difference in spool up. I absolutely can tell you the difference in power levels. This turbo is as much as 95 percent of the Evo community needs to satisfy their thrills. Like David said, our car has 99 percent of his parts on the car. This is no sales promo, but the reason is 'they simply work and work WELL. Our performance is no accident of just throwing parts at the car. We look at our goal and use the parts that will get us there. I have no problem using parts from someone other than Buschur Racing. Our goals come first. I know, I read about all of the great parts from various places, but I would compare using both cams from the SAME manufacturer to using all of the 'complementary' parts from the same tuner/developer. They're designed to work well together.

 

What cams is your customer thinking of switching over to?

 

Sparky, I'm not sure if you're talking to me, but I'll address it. OKIX is my son and I do the tuning on his car. He relies on me to make the decisions as to which parts we use. As far as cams, (now you'll hear why I like being associated with Buschur Racing), when the engine build is complete, we'll be testing the currently used HKS 272's (used for the 10.87 run and the 481wtq/425whp dyno session), the Cosworth's and the new JUN 272's. All of course Mivec cams since this is a IX. David Buschur is donating the Dyno time and Daniel Buschur is donating his time to swap out the cams. My goal is to maximize the newly built OKIX engine so we can continue to pursuit our 10.5 goal. I'm certain we can get very close using this turbo. This type of community support is just ONE of the reasons I continue to use Buschur Racing. The only way we can pay them back is by using their proprietary parts as well as their 'off the shelf' type parts. It keeps them in business, which keeps us moving forward in the performance arena. Back to the cam comparison: I expect to be able to do the testing within 2-3 weeks. Depends on the head work completion.

 

Thanks and good luck to you!

 

9ses9 thanks for your replies and keep up the good work.

I must say GT35R's in the 9's and Green's in the 10's... it's pretty amazing stuff from you and Buschur. Not many other people out there duplicating that.

What type of 60 ft's was OKIX doing? What tire pressures? What type of tires? What type of launch control? Ignition retard? Rev limit?

Totally understand if some of that does not want to be revealed.

 

At Norwalk, the best 60 was only 1.589, but we have had 1.53 -1.57. The 10.87 was 1.60? I think. Tires are usually at 20 front, 21 rear on QTP Hoosiers. We've also used Nittor 555R drag radials in 245/45 17's. Had several 1.6x 60's with those. Launch is stock ecu 2-step. If traction proves to be intermittent (like Norwalk was), I actually RAISE the 2 step, since I think wheel spin does less damage and can be more consistent than letting the engine bog, then spin, then bog. I had 2 step at 7200 for Norwalk on the last 4 runs. During Competition it was at 6949.
Ignition retard on launch I assume? No retard, normal progression in load/rpm range. I DO log the launch path through the rpms/load cells and have been a little more aggressive than most probably. But then again, we're using Import so we can get away with it. As far as peak torque, I'm currently at 15 degrees timing at 4000. Rev limit is set to 8300, but QTP's are 26.1", so when we use those, we won't hit 8000 in the traps. Rev limit timing is 28 - 29 degrees. Hope that helps. Don't ask for my maps to be posted though. You got more than I've usually given. Just trying to help those in their quest.

 

I know I saw it somewhere but I cant find it. Whats the weight of OKIX with him in it?

 

Wow, 15 degrees at 4k rpm, import gas must be awesome. I have never had a chance to use it but that timing is really aggressive.

What do you think of the nitto's overall? I was thinking about getting some drag radials but I don't want to have to change my brakes to go for smaller wheels. I was thinking either nitto 555 or BFG Drag, what do you think?

 

Weight is about 3180, but will soon change to abut 3080 or so.
dudical26, I actually like the Nittos because they were really easy to dial in. They're not as soft as the QTP's, but if it's hot, they'll hook. They're best attribute is consistency and ability to dial in. Just not the very best for maximum traction. I like the BFG compound better, but tire size is limited to 225's.
Timing is aggressive, but fuel and HOW you reach the timing/loadcell is important. I call it 'Sneaking up on maximum timing'.

 

Guys, I keep hearing about these EVO Green Turbo's ...

There not doing the numbers you guys are getting in the states, NO-WHERE NEAR THEM.

We must have different air downunder....

Best I've seen from a EVO Green, 98RON, Exhaust, Intake, Cams, PowerFC - is 253Kw @ the Wheels.

Is there something missing here, Race GAS, NOS ... what other things are you guys doing to these cars ... is the 1/4 mile stretch shorter in the states ???

 

No, the car is longer here, so it covers the 1/4 quicker.
We dont use Nitrous, but I think there is a dragracing thread for those that do.
This turbo can make lots of boost and use lots of timing, provided the maps are carefully built. Not everyone is going to make the same power, even with the same parts. A good tune is critical to squeezing everything out of the turbo potential.

 

VP Import is some serious sh**!

 

The key to unleashing the green is the tuner, and secondly, the right combo of parts, and supporting parts. RIPWRX, you guys running bigger injectors with the green? how about bigger fuel pump? It needs bigger injectors.

A friend of mine made 320 on California 91 octane fuel, on a mustang dyno. He hasn't been to the drag strip yet, but numerous 300whp cars from that dyno run 12.0 and 11.9.

The same shop/tuner has made 350+ w/ 100 octane on the same dyno w/ the green.
