Well halfway across the country (Denver, 5800ft ASL) It must be really different than San Fran.. My Buschur "Stage 1" went 12.86@105. If "Stage 4" cars are running 13's at anything near sealevel they SUCK at driving.

 

FWIW no Buscher stage 4 Dynoflashed cars ,when I ran my car, ever put down the times me and Smoggy have out here. Many examples to speak of and I am only chiming in as a voice of reason. Curt Brown puts down an 11.3 with more than a stage 4 but people are led to believe that low 11s can be achieved safely and reliably with an averaged tuned stage 4 with AEM or mid to high 11s with Dynoflash. Al you are using his achievement to boast that you can get others in the 11s on the stock turbo. Possible Al but not the norm. Average drivers with straight BR stage 4s on good days run low 12s but as I have seen are inconsistent. To date fastest BR Stage 4 I have witnessed was 12.4 at 112-114mph I believe. Another one I know of did 12.3 but claimed 12.2 however I found out otherwise. Same track me and Smog both did 12.2 me on 100 oct at 110-112mph and Smog 12.2 at 113mph on c-16. I ran 12.2 5 times with 1.77 being my best 60 and three 1.8+ 60s. Track sucked for traction. Curt good job and you are a DSM/Evo drag racing guru.

 

Thanks for the support Al and you other guys. After reading all these post I think I will give it one more shot before the end of the year. QCR is closed, Norwalk is closed and PRP doesn't have a Sunday T&T, I work Saturday's so I need a track with Sunday T&T to get 5-6 good passes in.

 

ATCO?

 

A lot of these guys are not professional or habitual drag racers. Many of them use their evos as daily drivers and commute with them. Many of them in California has de-tuned versions for the local 91 octane with retarded ignition timing.

While memebership in the 11 second club is NOT the norm with reflashes, there are onbiously several guys who have done it.

My ONLY point is that if these amature sportsmen driving their daily drivers can go 11.8 and 11.9 with a through the mail reflash and a stock intake manifold, CLEARLY there is some room for significant power gains with a guy like Curt Brown (assisted by David Buschur) - two masterminds of DSM performance are working to squeeze out every possible drop of performance.

My only purpose in making these comments is to show that it is entirely credable and realistic for Mr. Brown to be going 11.3 on the stock turbo

IN fact - given his level of skill and the progtress he has made so far, I would fully expect that a 10.99 on the stock turbo would be very doable

(Especially if he roased the boost up a bit)!

 

Yeah Al this guy is no joke and his #s speak for themselves. Turbo upgraded type results with a stock ported turbo. Good stuff.

 

man curt nice run!! thats damn impressive. I just got tuned by Al this weekend. The stock turbo is insane. 30psi!! believe it. I'm still running stock intercooler and stock intake mani. Nice job Curt, keep up the good work and showing off how great this 16g is.

 

what a dick

 

Congrats on your awesome times, absolutely amazing. I was just wondering what other options you still feel you have left to make your EVO go even faster on the stock turbo (with out any Nos), do you feel 10.99 is still a realistic goal? What about shaving off some more pounds, not sure if the EVO is your daily driver, but there plenty of weight savings you could find and still keep your EVO as a daily driver. Could shorter gearing help also? Is there still some more power you can eek out?

 

Congrads curt....Im going to try and catch up on that stock turbo set up....with Davids help. Ill be running There stage 1-4, AEM, CryO-2, alcohol kit, ported head, egal rods and wesco pistons, and exedy twin disk. Hopfully I can get some good time out of the car. Wish you luck bro on the 10's.......its gota make you feel good to run better times on the stock turbo then many with turbo upgrades....

 

Curt, I assume you are still running the stock 9.8cm^2 turbine housing. Perhaps switching up to a 10.5cm^2 housing may bring you closer to 10s. Or you can try the TME titanium turbo. I'd really like to see what that turbo can do in your hands.

 

Guys, I've been saying for ages that people aren't taking advantage of the stock turbocharger like they could. Curt is, plain and simple.

My car is running 117.55mph in the 1/4 with the same compressor and turbine, but a much smaller exhaust housing. My best mph is 118.02. And I'm certain I haven't gotten everything I can out of it. My car is a full weight 2G Eclipse. 3150lbs. Curt's car is an Evo RS, so it is probably pretty close to my car's weight stock. Then it is lightened on top of that.

Also, you aren't factoring in the increase in power you can see from cold, dense air in the fall in the north east. We are running these turbos at their volumetric limit. There are only so many air molecules you can fit through the small compressor inlet. Cold air is denser air, so you can fit more molecules through the cross-sectional area of the compressor inlet. It doesn't matter if you have a 100% or even 200% efficient intercooler if you are pulling air through a straw! You won't get any more air through that turbo, regardless of how cool and dense it is after the intercooler! If you can do anything to reduce vacuum at the turbocharger inlet, you SHOULD! It can make a big difference. Things like larger air filter to compressor inlet pipes are important, so are less restrictive air filters, etc... And I'm sure that changing to a different type of air metering can make a difference to reduce vac at the turbo inlet.

I know some people have stated that "I ran blah blah with the stock air filter in place, so you don't need to replace it." With a larger turbo that isn't seeing stratospheric shaft RPMs and the upper 1/4 of the map, that might work fine. But if you really want to lower your position on the compressor map (pressure ratio) with a small turbo, you can either lower your boost (counter-productive), or you can raise your turbocharger inlet pressure (very productive).

Every little bit counts. Some people get it. I've been working on my car with the same basic 16G setup for 5 years, now, but I'm not willing to spend the bucks to lighten my daily driver. Curt is willing to lighten his car.

Nice job, Curt. Keep up the good work!

 

Curt, This is Eric from AMS. we met at the shootout.


YOU'RE AN ANIMAL!!!!!!

that is all

Eric

 

Island Dragway in North west NJ is open on sundays for test and tune untill end of nov. Ill be there every week, and Im very interested in seeing this car in person.

 

Curt Congrats nice runs.

Since I have nothing to sell and no business to hurt let me speak my mind.

It has come to my attention that most of the people who buy evos are truly soft core. When i say this they seem to have not been exposed to the many yrs of the eclipse/talon experience that was going on here when there was no evo. The evo comes everyone raves, they run out and get one. The evo is a very similar car to the talon/eclipse, more so than most will understand, there is no rocket science in making them go fast. Look at who has the fastest evos, people who were in the DSM scene, they have the advantage of seeing most of this already.
Curt Brown was a trend setter in the DSM world, mitsu 4g63, all wheel drive, no nitrous. This guy isn't like some of your tuners, he gets the job done no excuses.He also did a galant vr4 that ran 10.0 or so. He is capable and qualified, unlike some of the "tuners" who all of a sudden have popped up to be experts in the evo world.

When it comes down to the crunch there is a place where all this dynoing, and speculation and calculation gets put to the true test. A racetrack.

Some will cry "oh we aren't into drag racing". Well different strokes for different strokes. Tell you what though, if you are going to quote big HP #s and speculate about the HP you make you should be able to make it last for a 1/4 mile at least.

The real truth of the matter is that after all is said and done very few people can go out there and run at a strip and "prove up" the speculation and the hype, and there is alot of "hype".

Evo owners there are import races around, attend and see for yourself what it's all about. Don't listen to some of these guys and their marketing hype, tell them you want to see the times that they run with that million dyno hp. should prove quite amusing.

NHRA, NOPI, etc, surely there are some results from this yrs races that show what the tuners can do.

Congrats again Curt.
