To make my car a redlight killer

First of all I should invest in a aftermarket ECU like Autronic with "Launch Control" and a "responssystem" to get the boost up before you launch.

After that i would invest in som real tires whith high sides like the MH dot tires to get down in something like 1.5-1.6sec for the first 60feet..

The last thing.
Is probarbly(like someone in the thread mentioned) having a spare transmission lying around..

whith this modification I proberbly would be able to get down in a low or middle eleven at the quarter mile....

That´s my recipie I think :-)

Well, I'm only 2k away from my PPI when I was told it ran Very well for an 86 951 (by Auto Atlanta techs). The bost comes up as normal (peaks around 1.8bar on the stock guage) and it FEELS like there's boost - just not below 4k. So for a few seconds, from 80mph, the Explorer creeps forward till we hit about 90mph and the RPMs come up. Then it's a non-issue. But her V8 just has the torque to move that tank a bit quicker (not faster, just quicker). Not to mention, it FEELS quicker when driving it too... (could be perception from being so far off the ground and in a woblly SUV vs. being closer to the ground in a vehicle designed for speed).

I'd need to ride in another stock 951 to see, but I really don't think it's running poorly. Or maybe I'm just so used to the grunt of my 3/4 liter motorcycle that the P-car just doesn't stand a chance?

Like I said, maybe I just need to trade in for a Geo Metro - then coming back to the 951 would seem great. <img src="confused.gif" border="0">

Like I said... You've some issues to deal with.

First off, a 1986 turbo should make boost much sooner than 4000 rpms.


Put on a Bursch test pipe and see what happens.

Also, maybe the wastegate is weak (very common).

Brian,

Bring your car by my house, I live in Marietta near the square, I'll take you for a ride in my car and we'll go for a ride in yours. We should be able to figure out if there's something wrong.

Brian McCoy

Sounds good Andy - it'll have to wait till after New Years though... (I'm about an hour away from heading out of town to my GF's parents place).

I work right off 285/75 on Powers Ferry so it should be easy to meet up sometime. Thanks for the offer..

Ok, so Tony - wastegate springs I've seen stuff about (commonly shimmed ~5mm) and that's easy enough to do (heh, I don't mind spending time but funds are limited). I'm sure a MBC (alla reliaboost, LBE, etc) would help too though I'm not absolutly sure.

The car really does run like a top though - I've used .5 liter of oil in 2500 miles, average ~23mpg for the daily commute (27~28 on the highway) - so it's performing well in the 'mechanical efficency' area. Just a thought, but it does have the OEM cat - perhaps that's due for replacement (111k miles on the car). I don't have emmissions to worry about.. but again, test pipes are seriously expensive for what they are (at least the ones I've seen).

*shrug* I'll have to wait till Andy and I get together to see.

I second Tony G's Bursch testpipe recommendation. That, and a LBE would TRANSFORM your car. All for about $150. (Assuming $100 for used Bursch and $50 for used LBE).

tazman

Yeah Brian you deffinately have something wrong, my turbo S would see 1bar of boost before 4000rpm with an LBE. Now I have the AVC-R and shimmed my wastegate and I hit 1bar around 3600rpm. I think I can get that down to 3500rpm playing with the AVC-R a little more. The numbers I stated above were obtained in 3rd gear start at 2000rpm and floor it.

Andy

That's fine Brian, just let me know when you get back in town. Several of us local guys have tried alot of stuff so we'll help you out, my friend might still have my old LBE or his MBC if you want one cheap. Test pipe helps too, why don't you have to worry about emmisions? I would recommend a set of Danno's chips too and you'd be in pretty good shape. I have the Bursch pipe, no boost control (spring tops out at 18psi,) number 6 hothouse spools up pretty quick so I get a 1 bar at not much over 3000 rpms. My chances of meeting up with something that can pull stronger on the highway from 80 in 5th are pretty slim. <img src="graemlins/burnout.gif" border="0" alt="[burnout]" />

CPTdooberhead

If you want off the line neck snapping acceleratin, you should go with a a 930 Turbo. They can be made very violent.

Danno

I think Eddie Bello's pulling wheelies in his 930 can only be categorized as a "massive street car"... heh, heh...

What? You can't pull wheelies with a 951?? <img src="graemlins/roflmao.gif" border="0" alt="[hiha]" />

My dad has 98 Exploder with a sohc V6 - 205 HP I think. Because it has traction control (transfers power "from the wheels that slip to the wheels the grip"), it could smoke most 2wd muscle cars off the line when it's raining. Under any other circustances the 951 stock or running on two cylinders would put it to a very severe shame. But the V8 has allot more torque than the V6 so that's probably the difference.

With my Turbo Cup chips and test pipe, my tires start to squeal at 3200 rpm'ish so the boost is there pretty quick on my car.

ill be selling my boost enhancer whenever the electronic boost controller arrives, let me know if you want it. it may be a week or two though..

Would a Test Pipe require extra fuel/upgraded chips?

No, all it would really do is free up exhaust flow and therefore make the car a little louder and more peppy. This of course is a step to more horsepower, which will require extra boost/fuel/chip upgrades. It certainly doesn't hurt to install a test pipe, but be sure to keep your old muffler/cat so you can bolt it back up to pass emmissions tests.
