I am starting to wonder if these cars just dyno low? Every time mine has been on the dyno it smells like the breaks are trying to control tire spin, after one pull the ABS light is on (not uncommon with modern cars) and after about five pulls I can not get the trans to cooperate any longer to make more runs.

I ran a 400rwhp cobra that had a 450-600lbs weight advantage and we were close to even motor for motor. I ran my buddies full bolt on and camed C6 vett with a huge advantage in weight and power and from 40-120ish he can only pull about a half a car on me mainly from 80 up due to areo (running agian with the spray i should have him). That dose not make much sense for a car that only has 370ish rwhp and weighs as much as we do? It is not like we have bullet like aerodynamics either?

 

qwikcat, when I dynoed last spring the rear tires must have fought the rollers too. The smell of burning rubber, flashing DSC and eventual ABS light gave away that despite turning off DSC, the STR's ABS never entirely disengages. This's the likely culprit behind near factory dyno results following mods. Wonder if disabling ABS during pulls will allow us to measure full rwhp? On the street my STR feels like 400 hp at the wheels, definitely much quicker from the get-go through the 1/4. Nailing her at 90 mph brings 130 mph in just a matter of seconds, and she still wants to pull hard...almost frightening power from soup to nuts. Try disabling ABS while dynoing?

 

is it hard to get the str near 400whp??

 

No...

 

Mine is real close on motor, I suspect even closer then the dyno shows with the results it gets , and well over on a small shot. Guess the track times will tell the true story soon as it gets warmer.

 

qikcat, you should update your times on dragtimes.com. I am tired of people reading car and driver and thinking we have 14.00 second cars.

 

How near? I don't recall a 395+rwhp. Very few dyno results on here, though.

 

Never been on that site but I will once I get some decent slips this time out. My trap was low on my 12.89 from the 60' times, by the time I figured the car out it was pretty hot and I have a lot more power now. With spray I hope to get it in the high 11s. I know it makes the power from the recent cars I have run, getting it to launch and 1/8 mile well is a whole different story!

 

I see no reason why the STR couldn't dip into the low 12's on motor alone, DragTimes.com posts a 2000 XKR (4.0 s/c) with a 12.4 1/4 mile, done with just low gears, ported blower, and exhaust.

 

On the track, if you can get a "cool" run and I say cool vs cold because you want your coolant warmed up, it would help to get you into the 12s...But at a typical track, you got dozens if not a 100 cars in front of you and you're constantly starting and stopping to move up the line. End result, by the time you make it to the staging area, you're already heat soaked...

If wonderful laughing gas isn't your cup of tea, you could always get a 90lb mistress and let her drive the car...

 

LOL! Or...lock up the steering wheel, wedge a cane between the seat and pedal, then throw her in drive? From what you describe at the track, a "Chiller Killer" can prevent heatsoak. Hey, I wouldn't mind a "Sneaky Pete" 50 hp NOS shot. This may settle some of those close street duels.

 

Okay here's my anti - thread jacking "sandwich" of comments...

The magnaflow cats sound great...
Ah...The sneaky pete, aka the gateway to the 10lb bottle...
I bet the gas would exit through a magnaflow cat and X-Pipe fine...

 

10-4 bro. During a duel I can see an STR owner taking a thumb to up the cover of the NOS switch...heck, I guess the other car would likely be doing the same?

 

Shoot, I too must hi-jack this thread: Is there a gasket that seals the EGR to the intake manifold or is it sealed by form-a-gasket? I ordered a new EGR. The dealer said the illustration doesn't show a gasket underneath the EGR.

 

yes there is a thin metal gasket smaller then the tube gasket. I can dig up the part number tomarrow if you need it.

 

03xtype, sure would appreciate the gasket number, thanks.

 

03 STR EGR valve to intake manifold gasket P/N AJ88560

 

would you mind taking a video of your exhaust and uploading it to youtube? could be a good thing for other members to listen to.

 

As my signature states, I don't have an exhaust, just high flow cats which hardly change the sound of the car; just a little more throaty at lower RPMS...I didn't notice any difference at WOT within the cabin...

 

I have a soudclip of mine I have emailed to a few members. It is a little different with the borlas, if you would like it just pm me your email.
