Default What do you think QM times will be for my 04 STI (454 WHP and 457 WTQ)?

I am on my third WRX. My last one was an 03 bugeye with mild mods, full exhaust, cold air, stock turbo, manual boost controler set to about 16psi and BOV. This car ran around 13.7 QM. I have had my new one for about 3 months. It is a 2004 STI and was built and tuned by TopSpeed of ATL Ga. The car produced 454 AWHP and 457 AWTQ on the dynojet dyno. I'll be going to my local track soon but I thought I could find out what to expect from this car through this thread.

Mods include: Garret Turbo tuned @ 26 PSI + meth (don't know the turbo model/type), SMC methanol injection kit tunded for 80/20 meth/water mix which starts spraying @10 PSI, 850cc injectors, Walbro 255 fuel pump, Perrin munual boost controler (26 psi), Perrin FMIC, turbosmart BOV, Cobb Tuning access port piggy back ECU, Greddy Full TB exhaust, down pipe, up pipe, Perrin Cold Air Intake, Short through shifter and I have recently added a new ACT sprung disc 6 puck clutch with a 620hp capacity and a new 15 lbs flywheel. I'm still trying to find out what or if any internal engine mods have been done because I bought with the mods and tune done. All but clutch and flywheel was done before I owned the car, Some recent post have some member thinking that the car has forged pistons. This car is on street tires (Nexen N7000s) with 18in wheels and has no weight reduction done.

I am thinking it will run in the low 11 sec range. Am I about right? With a good driver, is it possible for this car to run high 10s?

Maybe this vid will help? In the last part of this clip I let off at about 103 and was kinda babying the car. My girlfriend was in the car with me filming the vid and this car scares her a bit. We have been together for over 6 years and I have owned a subie almost the whole time but not one like this.

It is difficult to figure out what times you will run from just horsepower and torque numbers without even knowing the dyno model. More information is needed to produce an intelligent estimate.

ask Topspeed since they built and tuned it. they would have the best idea.

but the biggest factor is the driver so an 11.xx capable car can go 14.x with a crap driver.

wouhaa! who tuned the car? 454 whp with stock internals, they, usually, don't recommend that much boost on stock internals.

Topspeed has a dynojet, the car is 04 sti which is the lightest of all the STis, but you have 18" wheels with crappy tires.

I think the car can run mid 11s with a good driver

Much much more beat on ,possibly, by god knows who, damn thing has even been in off road rally, but you didn't know that, because it was really clean looking when you bought it all built and such... ... what was that had to replace the turbo re build the engine, oh no... the tranny is starting to grind ... You never know....

Back on topic I would say this car has a good 11 second pass in it, but to the OP don't let that meth tank run dry... on 93 I would be worried about the engine at WOT with all that boost and no meth so keep on eye on that...

I did some resarch before buying this car to make sure that the build would be reliable because its a daily driver. Everthing i found said that the stock internal can handel up to 500 hp. Is this not true? I am not as educated on the build as i would like to be. The prior owner was not much more educated than I am. He droped the car off at TopSpeed and told them to give him the best of the best for $8,000 to $12000 while keeping reliability in mind. TopSpeed is a highly acclaimed wrx tuner across the county. I do have the dyno sheet showing the HP and TQ levels. The car may not have stock internals. Being that TopSpeed had the fredom to build the car as the saw fit, would they have done any mods internally? If so what would they have done?

I wonder if TopSpeed keeps records of builds and tunes that can be looked up by customer name?

All the information I have came from the previous owner. I know that he had the money to build the car and never raced it. The car had not been driven hard. I am almost sure of this because the guy was scared of it. When I drove it he acted as if the car had never seen 7k RPM. I really think I got a cream puff out of this guy. I have done enough research when I had my other two WRXs as to what mods I would like and the listed mods are not just copied and pasted wish list, they are the mods that I know for sure are on the car now. If I were just pasting mods I would have listed the turbo type but I truly dont know it. As for my driving abilities, I have confidence. I have been racing one way or another for the past 10 years and am very capable of a good reaction time, a good launch and good fast shifts. I have not launched this car hard yet because untill last week it had the stock clutch in it. I am currently in the 500 mile breakin period for its new ACT 6 puck clutch kit. Once this is done, it's going to the track. With my 03 bugeye, I would frequently launch it @ 5500. From what I understand this new clutch will be able to handle a hard launch with the cars current TQ levels. I just hope 1st gear holds up. What are your opinions?

It was much cheaper. I bought the car for 18k with 25000 miles on it and all the mods. The guy invested nearly $14000 worth of performance, interior and exterior mods. I would also like to know more about what suspension mods are done. I took it to get new tires and the shop also dose suspension work and the guy told me that it was one of the best looking setups he had ever seen. It has torsion bars, easy soft/stiff and camber/caster adjustments that can be dialed in under the hood. The car handles very well i just dont know what brand/type ect.

I think Scott TopSpeed's tuner keeps the records of all his tunes, give him a call.

8K is not a lot, your car probably has forged pistons. Dude just ask the previous owner . Did you do a compression test and leak down test before buying the car?

You have the 6-speed tranny, the tranny is almost bullet proof.

Here is a link of a vid of my car. This could help? I titled the video with the estimated flywheel HP. If what I have read and understnd is correct about the 20% loss of power from the flywheel to the ground these number should be about right based using reversed math starting with the known number of 454 WHP and 457 WTQ.

no i did not do a compersion test. I guess that would have been a good idea. The car run very well though. I am a driver but not the best machanic. I dont know if I got in over my head or not... I just wanted a new toy. You think they would have done forged pistons?

Oh nos lambo doors , it looks good. It think you have a perrin FMIC, with a turbosmart BOV and megan racing coilovers. Check the marking on the turbo, it looks like a 30R to me

I have already raced a new Z06 from a 70 mph roll to 140 mph in a closed off industrial area and pulled a good 5 links on him. I feel confident that the car will break into the 11s range.

Man I didnt know that every one seems to hate lambo doors. At least every one on this site and on youtube. I was not that excited about them when I bought the car. I felt like I am a little to old for that ****, but they have been growing on me and other than on the internet, they get compliments almost everythime I go out. People seem to love them, they stop in their tracks and look when they open but I guess I can understand why some people think that there tacky but I can't see spending the money to switch the back to stock.

Thanks TDagen, I'm pretty OCD about watching the meth level. It has a
"low level" light on the SMC control module. But I still don't trust that thing. I take a look at the bottle often. In fact I posted another thread to try to find out if the machanic that installed the clutch broke the meth system. When i took the car in for the clutch install the meth pump worked fine but when I picked it up it didn't work at all. The mechanic said that all he did with the electrical system was pull the batery. I checked the ground wires for the meth pump, they were fine, tried the spray test and nothing. All the wiring was fine, I guess some how the pump just shorted out. I have sent it off to SMC. The guy was very nice and helpful over the phone and email. He is going to replace the pump and send it back. Its a very plug and play system, all I'll have to do is two bolts for the meth resavior, plug in the wiring and hook up the steal braided meth line.

I should have it back from SMC by next week. I will stil try to call TopSpeed to see if they have record of the build. Thank for the help.
