Quarter-mile times? 0-60 mph times?
I am interesting in what times the 951 owner has on their vehicles.
A friend on mine drowe the quarter-mile in 12.50 and 0-60 mph in 4.7 sec. The car is almost a stock 86 Turbo Cup with 360-370 rwhp (almost stock
). And after this winter that car is going to have another 50 hp, so a 12 flat or under that would be the target for summer 2003. My own ongoing project is first going to be used as a track car but also tested on a strip, a 11 sec quarter-mile time is my goal.
When I look at Lindesy, SFR, Huntley racing etc. they all have big turbos for sale and many goodies for our cars, but I have never heard about any 951 that have done any 10 sec or 11 sec on the Quarter mile, is there any car that has done that? And now I mean a car with the stock 2.5 litre engine.

Johan,
I will tell you this now.. these cars suck at launching, and are not good drag cars at all. In other words if you are looking for a drag only car I would recommend a mustang or camaro. My last clutch repair bill was almost 2k, certainly not something you want to be dragging all the time.
However on a gtech I have managed a 12.98 at around 115-116mph with 2850 plugged in for the weight. For my modifications look at my signature.
I know Rage2 has quite a bit of mods on his car and I believe he was in the low 12's with his car?? Rage you out there?

I think 70-100 or 60-100 mph runs are more indicative of the car's performance than the launch, because that involves many variables like the launching technique/rpms, etc. grip of the tires/asphalt, etc. Over at the pelican bbs comparing the 70-100 in gear acceleration times were fun. If I recall correctly mine were in the 2.8 sec. range (Floor it in 3rd @ 60mph, start timer @70, stop timer @100, then quit). This sort of testing is also much easier on the entire car, specially the drivetrain/clutch.
My car has recorded a 13.2 in the quarter and 5.0 to 60. A few runs later I broke an axle. Running 22psi a couple of days ago I slipped the clutch in 4th gear, so I will not be doing drag style tests anytime soon. That was with a completely stock bottom end, stock turbo, etc.

Ahmet,
I have experienced similar runs with my 86 with only a maf and tweaks. I notice that even those with high HP machines have a hard time getting below 12.5 sec 1/4 mile times. One of the 500+hp guys ran a low 12 132mph pass down the quarter spinning much of the way.

My view of 951s at the strip is like this. When the tires don't slip, the clutch slips. If the clutch and tires don't slip, then the engine boggs, lose boost and add 1-2 secs to the time. If everything works right, and it hooks up, you ran a very high chance of breaking somthing in the drivetrain.
That said, Here's a Turbo Magazine article on a 9 sec 944. Don't know anything about it. Anyone have the magazine that can clue us in on what the article says?

Ok, so it´s seems to be hard to hit a 11 sec strip time. I know that the start is real hard on a 951 due to the boost lag. But how about the transaxle and the drivetrain, do the break or is the quality good on these parts?

Ok I think you´re right. 12.5 sec with that horsepower in the engine is real good. By the way call me, it´s about the garage Gustaf.

Here's my take on it...
With a big turbo (like myself), you get lots of top end power. Off the line on street tires, wheelspin like crazy unless you turn down the boost (like what I did). You'll bog regardless when it grips. What happens is you get a 12.7s run at a nice 117mph. I can turn up the boost in the lower gears and throw on some drag slicks, but the tranny or CV joint will let go pretty much instantly and you won't even finish a run.
With a smaller turbo, u get good power low end and high end, and you'll come up with a 12s run at say 110mph (guesstimate) because you'll have a great launch, but low mph so impossible to get into the 11's.
Unless the drivetrain is strengthened significantly, or someone runs an even bigger turbo on really really high octane fuel (I ran 103 octane), doubtful we'll see a 2.5L 944 run into the 10's or 11's reliably.

Still, anything in the 12's is really really quick. That will thouroughly lambaste just about anything on the road.
The owners manual for the 89 951 I have says 13.5s @ 105+ mph and 5.5s 0-60. My car has 260 rwhp (~+50 over stock), 275 rwtq, and a drilled cycling valve so you don't loose as much boost in the shifts. It has run 13.8 @ 104 mph with what looked like the most miserable launch imagineable - engine bogged bigtime. I'm sure it should get into the low 13's but I have to get out to a track to prove it. I think if you can get these cars to lauch by doing some clutch damage, they will run low 13's with only minor mods.....but who knows. It's one of those topics.....

When i tested the G-tech i only had the chips and a boost enhancer, my time was a average 5.2 sec. 0-60. I will test it again next year when all the mods are done.
I also looked to change my clutch to a clutch (In Sweden it is called Sinter??) That not allows you to burn it up, this one works like a on/off button. When i learned to make good starts sometimes is smelled burned clutch but most of the times I got real good runs. When i had the stock wastegate replaced with a performance and my performance chips installed I even won over my friend Impreza (tuned to 260 hp) not the first gear but when i geared up he passed by my side, so there is potential in our cars.
But of course if the car should be used on a strip, i should have bought a Supra istead. But I wanted a allround car and most a car that is outstanding on the track, and that´s where the 951 comes to it´s right. A real bad *** track car, due to the 50/50 weight.

Hi Guys
I think you are talking about my car! Even though I´m impressed by my car it hasen´t any 370Hp on the wheels, probarbly more like 350-370 on the flywheel.. But I´m pretty satisfied anyway ;-) Infact it looks like it´s hard to reach even my figures on the quarter mile...
The problem is that in Sweden we have this "damn" Supra guys and right now everything over 10sec is a slow car ;-(
My Goal is the too give the "dentists" in there Ferraris something too think of when I pass them on the highway and on my favorite roads.
I think it´s a lot of fun to bring out some "funny" faces <img src="graemlins/wave.gif" border="0" alt="[byebye]" /> on owners to 360 Modenas and other 120000$ cars!!
Regards
Pete

I'm surprised I haven't heard of anyone using the launch control and traction control features in the more advanced efi systems to get good quarter mile times. The launch control provides a programmable button or sequence activated rev limiter which would let you open the throttle completely and have the efi limit the rpm so that the turbo could spool. The traction control is programmable to provide a specific amount of wheel slip, which would let you stay in the throttle. Also, these efi systems offer a no lift shift system which would allow you to keep the throttle open while shifting, without your car enduring the stress of a powershift, which would pretty much eliminate lag.
Of course, using all of these systems, especially with a car making 350+ lb ft of torque with big wide sticky tires, would probably result in broken drivetrain parts.

My traction control is in my feet! Thise times and mph's posted earlier are indicitive of lots of wheelspin and sorry 60' times. I drag race religously in my stang. a 120 mph trap speed will get you into the mid 11's easy if you have traction (ie: 1.5 60' times) These cars are very hard to launch on boost and not kill the tires. BTW I have broke a cv a axle stub (in the trans) and a diff cross pin none of which happened while dragracing. Usually cornering hard or wrapping donuts!
