Shooting for 11s on streettires is a helluva task,i hit 7.82@94 12.06 @113 on my pilot sports last nite on TSW chrome wheels.1.82 60 ft leaving off idle rolling into the throttle

 

If you want a 10 s car you have to look at :

How you get away with 26 psi and no intake manifold pressure codes,just curious 10s is doable but not really my goal on street tires

 

Watch "Srt6 Crossfire vs Mustang" on YouTube

 

The best I ever achieved on street tire was 12.7. When I caved in and bought drag radials 12 flat was the new normal. I don't know how you do it on street tires. I failed time after time.

Pilot sports and leaving off idle

 

Thats a mysterium for me to .I controll the fuel by my AutronicSM4. But the pressure, i dont know.
Last race, yesterday, was a Audi 90, 1200 whp, and i lost by 2 cars. I love my Mercedes.
I only use 180000 rpm of the Supercharger. IHI Supercharger is maxt out at 22000 rpm.
So, i can get more pressuere. And more HP
11 sec is no problem for you on the street. S/C pulley or a Crank pulley.
Good luck

 

Nameless tranny tune Les who does that been thinking bout s tranny tune for a while

 

I need to revise that. I had an Evotech TCU but I couldn't make it work for me. It shifted slower than stock and worse than that, I kept hitting the rev limiter in the PCM. MY PCM rpm limit is raised to 6500 rpm and the TCU was set to shift at 6400. Too close together. When I swapped in a 3:27 the TCU came out and another TCU went in. I'm back to stock shift points. On my car, the extra 400 rpm was worth 20 hp. If you can get it to work, power is there. I haven't been back to the 1/4 mile since swapping in the 3:27.

I have been on the fench about a tranny tune probably just get some solenoids

 

Mods are code 3 pulley.needwings modded stock manis,dcai with large filters,Johnson pump extra large heat exchanger,new oem wire s ,1 step colder plugs,sl55 fuel pump ,e55 fuel filter a few more psi that crossfire and a 55shot in third gear only ,oh inmotion can tune car hit 18.5 psi with the code 3 ,car makes 350whp and 365 tq without the Nitrous

 

So Les I want faster shifts what do you recommend

 

So do I! It's seems simple enough but I guess it's not. If you find an improvement, let me know what you did.

 

I researched the blue tops years ago and it seems we already have them. The MB guys indicate that 2005 forward are blues and prior years brown tops. They also indicate an improved upshift but an equally hard downshift coming to a stop.

It's in the tuning of both the ECU and TCU. A lot happens prior and during the gear change. Going from my data logs: timing is cut drastically, throttle body partially closes, supercharger disengages and then the shift happens. (don't know about the exact order) The sequence that happens before the actual shift is a big part of the lag we feel. You can feel it equally after the shift as timing returns and you get 100% throttle back.

 

Back on track. yeehaa

Wrong car to start a race with. 4 pcs of M/T and 1200 whp. Lost by 2 car lengths. Thats not so bad. Audi 90, 9,73 sec at 800 hp. 1200 whp = ???
Nice race, and realy fun. Love this

 

Ok finally got it tonight pulled a 11.97@119 on street tires,for some reason I lost 2mph in the 1/8 and gain 2 mph on big end 7.83@93 instead f 95 119 vs 117

 

Nice going. I'm trying for the same. Pretty close, but I need to shave a little over a tenth. Maybe finally installing my big manifolds will do the trick....
