Are we to understand that Joe is turning to the Dark Side?
Joe- I'll get mine dyno'd with Vitesse Chip, 3 bar FPR, test pipe, and Profec type S & post the chart when it's back on the road. Then maybe 3" exhaust and Vitesse stealth MAF and bigger injectors. I'm hoping that will get me to 300 HP & TQ.

I dyno'd 300 rwhp/289 ft lb torque on a Vitesse Stage III - Pump Gas (91 octane) and 15 psi boost. This was untuned using the Vitesse board (not chips) and without the SMT-6 hooked up. I'm hoping that 330 rwhp is possible after some tuning.

I put on a lindsey 3" exhaust, lindsey chips, EVC boost controller set to 15, Stage II maf, and adj FPR on an 88 turbo S and we put down just over 300rwhp on our mustang after tuning it with mafterburner. Car was completely stock until those parts. (Customer's car)

Doc, show us the dyno chart. A 951 with a K26/8 making over 300rwhp at "15psi" boost is unheard of, you might be on to something.

1.5 bar, maybe?

Well maybe.

I am considering some of my options. First plan really would be to run a baseline dyno just to see where I am at now.
Then afterthat pull the motor do all the seals and gaskets, rod & main bearings and minor headwork. Most just to ensure all is working well. While I am in there I will probably drill the crank and baffle the oil pan incase I really start tracking the car hard one day.
Now wastegate and turbo. I'd rather stick with the stock K26/8. It is one of things that makes an S what it is. So... I'd like to stay with that. Of course if the turbo is toast... then rebuild, vs replacement. Things will change then.
Wastegate is may need to be replaced. I would probably put in a Lindsey one rather than a Tial just for a easier bolt in. It all depends on how old and worn it is.
So then put it all back together and run her across the dyno again. See if I pick up an hp with the fresh head. I figure I will get some where on the order of 5-10 hp just by ensure proper valve seating and makign sure all my plumbing is clean and working top notch. Maybe not, but that is what the 2nd run is for.
Then depending on the feel of the car I am thinking about a chip. Vitesse seems the only way to go right now. That with MBC should bring me up to somewhere in the 270 whp range. Not bad really. Now 300 is not that far off and I know a supposed 305 rwhp car that supposedly has a stock k26/8. I don't know the details as the owner is not really into the details of the car.
Now I figured 305 whp is a bit of a reach with just chips, MAF, and the k26/8. Of course run lots of boost and you can do anything, but too much boost from too small a turbo means lots heat and that is bad.
However 300 whp is really nice round number, however as John likes to point out "peak numbers are not what we are after". I have the same thoughts so I'd be much happier witha 270 safe, reliable, "fat power band" whp (or even 240) over a peaky, ready to blow 300 whp.

Edit: And I am not pimping Lindsey racing's products at all, that is just what our salesman sold the customer 8 months ago, and just what I bolted on and Stephen tuned, and that's what it did.
We also had an 86 turbo, with a lindsey stage II maf, adj fuel pressure regulator, 3" exhaust, and chips (don't know whose they were, I didn't open the DME) put down 282 to the rear wheels. 160k miles.

Maybe you didnt read John's post the k26 is a TINY turbo:
Don't be too concerned with peak numbers. You only hit the peak at a certain RPM, but you spend most of the time at other RPMs. Shoot for the largest area under the curve. On your car the K26 is the limiting factor, it just does not flow enough. If you want a solid 300rwhp, matching torque and a flat beefy power curve, you will have to upgrade the turbo (and associated components to support the added power).
