585whp is definitely possible, given a big enough turbo and a built engine. Here is a thread on SRTForums that someone posted recently:

But I don't know of anyone that's made those numbers and has a dad w/ a 1000hp Viper...

One of the big differences with the slicks is being able to run more boost in 1st and 2nd gear. With the street tires, I have the boost turned down quite a bit, probably dropping more than 100hp for those 2 gears. On the street tires I was also keeping the boost on my "Street" (non-race-gas) tune... roughly 400whp. The 11.7 runs were with the boost turned up on race gas (~485whp). However, once it cools off, with the slicks, I should be able to hit 11's on the street tune and low 11's on the race gas tune.

I compared a recent 400whp street tire timeslip with one from when I ran a 13.8 stock.

The 60', 330, and 1/8 mile ET's were almost identical, so the car picked up ~6 tenths on the back half of the track:

Stock/Upgraded
60' 2.2 / 2.3
330' 6.0 / 6.1
1/8 8.8 / 8.8
1/4 13.8 / 13.2

With the borrowed slicks I was able to get 1.8 60's. I have some bolt on traction devices I made that will hopefully allow me to get a low 1.7 or possibly 1.6 60' with my new slicks.

 

hmm...if you could drop the 60s down even more..its gonna be scary!

figure, last year i was only turning 12.60s, with a.167-1.73 60s!

 

I'm counting on it. I figure if I can turn a 1.6 60' on street tune, I'll hit 11's or real close to 'em. I typically trap about 115 on the street tune, boost down in 1st & 2nd and not hooking until about 500' into the run.

 

Gawd, I gotta get a turbo!!!!, I would love having traction problems 500 ft into the run!
Mchat, It's easy to see from your MPH that you run hard on the big end of the track. 120 mph is low 11, high 10 second territory.

 

My car is getting faster now that it's cooling off (that and fixing a crack in my intercooler I recently found[&:]). I was at the track last Saturday and turned a 13.4@119 (well 118.8) w/ a 2.4 60' and a 6.4 330'... now I just need my drag wheels [:@] On the borrowed slicks I ran a 5.0 330'... if I can duplicate that on my slicks, I'll be running high 11's on my street tune (91oct Pump gas).

I was playing around on the street (out where there's nothing but fields & no other traffic) w/ a 750cc 1997 Sport Bike. Twice the sport bike roasted me so bad out of the hole that I had no chance, but I did get one good launch in and caught him and passed him in 3rd and put a car-length or two by 120. On the worst launch, the tires broke loose at about 1/4 throttle in 1st, broke loose @ 1/2 throttle in 2nd, and broke loose @ WOT in 3rd... and didn't hook up at all through 3rd. I roasted the tires all the way up to ~90mph, an 1/8 mile long burn-out. I guess I'm gonna have to turn down the boost for the "winter" here.

 

mike, are you closer to one of the fastest street driven SRT4s?

 

Probably in the top 20~25 nation wide. According to SRTForums list, I've run the 17th quickest time. But I know there are people with big turbo cars that either aren't on SRTForums or haven't posted their time (or haven't run at a track yet).

There's also a few people I know w/ big turbo projects that will be jumping to the top of the list by winter's end. (There's a couple of T67 turbo SRT-4's on the horizon, ~500whp on pump gas, 600-650 on race) My goal is to get a cage installed, get the car to run low 11's as is, then build the engine next spring, turn up the boost a bit more and a few months later add a 100 shot direct port (w/ a progressive gear-dependent controller) and hit 10's next fall/winter.

Unfortunately, in order to keep it streetable, the car will likely never see a sub 1.7 60' (well maybe a high 1.6...) so it'll have the trap speeds of a car 1/2 sec to a second quicker. My guess is that w/ the DP nitrous it'll hit mid 10's @ 135 to 140.

 

thats freakin sick...

so what stage are you, and what on your car is still OEM?

 

I'm using the Stage I ECU w/ an AGP GT3076 Turbo upgrade. The engine is stock crankshaft to valvecover; the clutch has been upgraded and the axles have been upgraded, otherwise the transmission is stock. Just about everything else (powertrain wise) has been upgraded or modified.

 

was actually wondering about the clutch and half shafts...whose do you use?
