Been quite the interesting year for Evos so far, AMS breaks their own record a few times, gets 900+ whp from a customer car, then tops that with their shop car, gets very close to 8s but can't get just the right run to do it, and finally tops out their dyno and hits 1023whp in another customer car (no nitrous). Now Buschur comes out this last weekend and lays it down.

Not to mention...

Shep still showing that he's the man when it comes to the 4G63 (1300-1400 whp no nitrous)

 

fast, but not sexy fast.

anyhow, 1300-1400 whp no nitrous is pretty amazing.

 

got dang bushur! thats badass...is that a stutter box i hear before launch?

 

That's just the 2 step most likely. Many many Evos have them since it's something that can be added when you get a flash.

 

Not bad for a "4 banger"

 

LMAO!

 

Is there anything left of the original engine? How much HP could you possibly get with such little room?

If you can do that to an Evo, I can't wait to see what they can do to a higher displacement engine.

Very impressive.

 

The BMW 4 cylinder 1.5l engines that were running in F1 back in 1981 and producing 900hp (no nitrous either) were stock engine blocks from the BMW 1.5l 02 Series with at least 60'000 miles on them. (They noticed that older used blocks were less prone to cracking). These blocks were initially produced back in 1962 (!) and the engines originally produced 80hp in stock condition.

(900 hp on 1.5l engine is equal to 1200hp on a 2.0l engine. Also Turbos back then had significantly lower efficiency numbers.)

 

I cant watch the videos at work... What tpye of gas are they running?
Just makes me wonder how streetable and how long the motor will last on something like this.

The owner of my company has a 12psi superchared SRT-10 and I think thats only around 800 HP. It's just 100% streetable and drove to work and back everyday.

 

Some of those 1.5L turbo's were running 1500hp in qualifying form, and thats nearly 30 years ago...1000hp per liter! Iron blocks definitely help, but some bikers have turbo'd their 1300cc motorcycles to do nearly 500whp on alloy blocks.

 

That first video is at Norwalk Raceway Park. I live and race there. When I fnally go F/I, i'll have Buschur tune it.

 

EVOs are scary...

 

How fast does it have to go to be "sexy fast"?

 

Not to be too nit-picky, but the highest number I've seen for those turbocharged BMW's was 1300hp, and even that was an estimation. The dyno in Munich wouldn't read as high as even 1300, and that number was arrived at by estimation only. That was in '86, the turbos of 30yrs ago didn't make anything like that kind of hp... Even as late as 1980 they wouldn't even make more than 500hp, at least not reliably.

The engines that were pumped that high never lasted long (and would only have been used for qualifying), and on race day they would've been dialed back, probably down to the 900-1000hp that globi mentioned. Unlike today, they would simply use different engines for qualifying and the race, so they didn't even have to "dial back" the engine for the race, or worry about the qualifying motor surviving 2 hours on the track after being run so hard in qualifying.

 

not as much hp, but sure is sexy fast

 

I was just thinking that a sub-9sec quarter is sexy fast, even if the car itself ain't sexy.

 

Evos' are quickly becoming the new supras...

 

Meaning they have a million horsepower but nearly all of it comes in the last 5 rpm before redline thus making them useless?

 

I'll take one over an Evo... much nicer looking

 

actually its the exact opposite

 

Brilliant, considering the RX-8 has such a wide useable powerband

Get a clue, these cars are not dyno queens.

 

yeah but they are so fugling ungly unless the evo X stays true to concept those looks nice

 

This is sexy fast:

It's an FD!

 

And if I recall that was a 10 second run.

 

That's a good question. I know the stock bottom end is pretty reliable up to 500whp but I'm guessing these cars have new crankshafts, pistons, connecting rods, heads, etc, etc. Not to mention the aftermarket drivetrain components. Needless to say those Evos in the videos aren't daily drivers. However there are lots of Evos putting down between 400whp and 500whp that are.
