Hi guys.
I'm David, the owner of the car. I've been a member here for quite some time, had a few turbo Buicks and a few old Buicks too.
Details on the car. For those of you wondering.
2004 Mitsubishi Evolution RS
122 cubic inch stock block
stock crank
stock head casting
Engine is our BR (Buschur Racing) Stage 3, which is all balanced, upgraded rods and pistons.
Head is our BR Stage 3, which is ported, upgraded springs/retainers, valves and o-ringed.
The turbo is just a new version of a GT35r. The car has made 700 whp on our Mustang AWD dyno in the past. This particular day it was dyno'd only in 3rd gear (which produces lower numbers as it is not 1:1) and it made 635 whp. Our dyno for reference reads very low compared to a Dynojet.
Back to the engine.
Engine runs a set of our custom ground cams, about .420 lift is all, hydraulic, stock lifters, stock rockers.
BR air to air front mount
BR 2.5" upper and lower i/c pipes
BR lightweight battery kit
BR coil on plug ignition
BR double pumper, stock fuel lines, stock fuel pressure regulator
1200 cc injectors (120 #'s)
BR fuel rail
Wilson Manifolds ported stock intake manifold
BR 65 mm throttle body
BR 3" turbo back exhaust with our bullet muffler
AEM EMS for fuel management, which I do the tuning on
The transmission is stock, it was rebuilt with new syncros in the spring of 2007. Transfer case, front axles, rear axles and rear differential are all stock. The driveshaft is a 2 piece standard steel unti from DEVO Tuning.
I have raced this car hard since it was new in 2004. In that time it has broken one stock drivers side axle and one aftermarket transfer case I tried. No other driveline parts have ever broken.
The car, if driven on the highway at 65-70 mph, will get 28+ mpg.
The boost on the 9.72 pump gas run was 31 psi peak. I turned it down for the next one to 28 and it ran the 9.78.
On the race gas passes the peak boost was 40, the datalog never hit 41.
I honestly didn't expect the car to go as fast as it did. I've been very stubborn in the past and refused to run a slick on the car because it is my street car. We've always run it on Hoosier QTP DOT's. The car ran a best of 9.42 at 155.78 mph with those tires.
The car was up 35 whp from the last time we ran it and we put the slicks on. I expected, on a really good run, to maybe see a 9.2X and that was my goal for this year. Needless to say three 9.1's in a row left me pretty happy.
How reliable is the engine? Extremely, you guys would be shocked. The last two problems I had were both from some failure that was a "freak". I lost a cam sensor which hurt the cylinder head. Just bolted another head back on. Right now two of the cylinders are down a little and it is probably from the sensor going, obviously it's not hurting it too much. haha
As for the 8 second EVO in Florida that was mentioned. There isn't one. I'm not sure who was being referred to but there are only 3, 8 second EVO8-9's in the country right now. They are all gutted tin cans, one of which I own. AMS, Buschur Racing and a guy named Brandon from New Jersey are the only EVO's to have run 8's. Our full blown drag car with a GT42r on it has only run 8.8 at 172.74 mph, MPH is there but the ET sucks considering how fast my car ran. My car is also quite a bit heavier than our drag car. We are going to work on that as the other car should be running in the low-low 8's but getting the suspenstion/trans to cooperate with 1,000+ whp is proving to be very difficult. As a matter of fact we put a small T67 Ptrim on the car and it ran 8.96 at 166 mph, nearly as quick with 250 less HP.
This car is no joke, it is extremely reliable is driven on the street, it drives extremely well, not really much different that stock other than the clutch being grabby and it being louder.
Thanks for the interest.
