How to run mid-low 11's....
I went to the track the other day and watched a bunch of fully built domestics go 10.50-11.50's-12.50's and I was surprised at the amount of mods they needed to do so. It got me thinking instantly how fast my blue car really was for such limited amount of mods and how great the evo platform really is. This thread is for the newcomers who may never stumble upon my 3 year old post about my 11.50 runs with such few bolt ons. The info I am posting below is the exact parts it took me to run consistent 11.50's on a very safe 10.50-11.0 AFR 93 octane(1 gallon of 110) tune. This car was a full weight GSR with no weight reduction except for spare tire/ jack and passenger seat removed. Bumper beams, door beams, etc were never removed. This car had no port work, stock TB, stock intake manifold, stock exhaust manifold, stock cams, stock intercooler, stock trans, stock T/C, etc. All that is required is the Buschur stage 2 kit. Essentially intake, exhaust, and a flash...
Stage 1: $1419
BR EVOLUTION AIR FILTER KIT
BR EVOLUTION 3" STAINLESS STEEL DOWNPIPE
3" HIGHFLOW CATALYTIC CONVERTER- I used test pipe
BR EVOLUTION 3" STAINLESS STEEL CATBACK W/ MAGNAFLOW MUFFLER
BR MANUAL BOOST CONTROLLER
BUSCHUR FLASH-I used Dynoflash
AUTOMETER 30-0-30 BOOST GAUGE
COLUMN MOUNT GAUGE POD
Stage 2: $979
BR EVOLUTION MAF PIPE KIT
EVOLUTION ODYSSEY MINI BATTERY KIT
BR EVOLUTION UPPER I/C PIPE KIT w/ TiAL BOV-I used 1G and Forge RS
Both of these can be found for great deals and cheaper than I listed, but this is the average...
Tein S tech springs $208
Exedy Twin HD clutch $1500
Here were the results:
11.61, 11.56, 11.60, 11.66, 11.56, & 11.59
60' 1.631
330 4.752
1/8 7.391
mph 92.90
1000 9.648
1/4 11.563
mph 117.35
60' 1.595
330 4.721
1/8 7.375
mph 91.78
1000 9.647
1/4 11.568
mph 117.12
Now for the tiny details most leave out. To duplicate these results on a regular basis you will need to do a little more investing. The stock clutch did fine and netted some nice low 1.6 60' times, but failed quickly. My recommendation is any nice twin plate clutch( I used the Exedy Twin HD). Most can be bought for around $1500. The tires and wheels that were on the car at the time were Volk CE28's with Falken Azeni's. The stock tires and wheels performed right on par with the Volks at a tire pressure of 18psi. But, it is my recommendation to find a nice set of used BBS wheels and just mount a Falken Azeni on them. I also used Tein S Tech lowering springs in the mix. There are no secrets, that is everything that was on the car. These cars will run mid to low 11's very easily.
That was the past, fast forward to the present. The same car is now under new ownership. Both previous owners made multiple changes to the car and slowed it down into the 12's(12.40's to be exact). Chris contacted me for advice and I gave him what he needed. He quickly duplicated the 11.50's and then went on to run 11.15@124 with the addition of E85, bigger injectors, 65mm TB, and ported BR exhaust mani. So in short, if you want to run low 11's with a proven easy mod path this is what you'll need.
I took it another level and went into the 10's with my new RS. Same proven mod path, same proven Buschur parts. Just went with weight reduction, stand alone, and slicks.
If anyone wants any help or guidance shoot me a pm anytime. Hope this helps a few dip into the 11's. Have fun and be safe...

two step setting and tire pressure's are critical. I liked 6500rpm and 18-20psi on street tires. 11.7 is still a great time. No problem, just trying to help others reach their goals.

well, the 6k may be a little low. But alot of it is driving style. I would step it up to at least 6400. I always launched at over 6500, but again it is a personal preference. Just gotta finesse the clutch foot. Dont want to break anything. What are your 60' times. Even on fuzions you should be able to get 1.6's.

Your blue Evo looked great man! So you launched at 6500 with RT615s with 18-20 psi in the tires?? The couple times I have launched with my rt615s on the street I spun a lot and my 2 step is only at 6k...but that is also with 35psi in them for DD...I would imagine they would hook a bit better with only 20 psi in them....Thanks for all the other great info man...

1.7 is not bad Poncho, alot of guys on here average 1.9-2.0,has your twin disc help out with your launching?
and most-wanted,was your blue car an VIII or IX? its crazy how alot of guys get such great numbers will such little mods,and others with big turbos dont have as much success,im assuming its all in choosing parts wisley and good driving

yes it was a IX. There is a big difference between 35 psi and 20 psi believe me. I also run through the water box and do a mini burnout to get the rubber warm. I have had 4 evo's and all have been abused the same way and I have never (knock on wood) broken a drivetrain part. Chris who has very little time in the evo tried this set up and did a 1.60 60' I believe. The trick is to get a solid high rpm launch and perfect the 1-2 shift. As I said, this is just what I have found to work for me.

Great post Most-Wanted, and I'm happy to finally hear someone recommending setting there two step to 6500+. I would drag race every weekend if it weren't for the lack of 1/4 tracks in So Cal, and your lucky to get 2-3 runs in a day on those that do exist! I went to the local 1/8 mile track a few months ago and my new E85 tune showed potential trapping 97.19(shifting to fourth) with a 1.8x short time and if my memory serves me right it was a 7.5. I never played with tire pressure, just wanted to see how it went down the track, and I have my two step at 6800. My biggest dilemma at this point is to look fore more power or have shep do his magic on the tranny.
