Personally, I think you guys are very optimistic... I've dyno'ed several turbos, and found that a stock car will make about 200 WHP. You can see on this chart that it took quite a lot of extra boost to make 250 whp (and that's a good running car (technoduck)).
FWIW, I've had nearly a dozen 951s on my dyno - all with different mods - and none have broken 300 WHP.
To the OP, I'd say you're at 200 WHP now, and with a chip - and your other stuff - you'll get up to 220 WHP.

These numbers seem really low to me and most of what I've seen on the net, maybe it's Dyno differences?

Can you post some dyno charts of what you've seen? 200-250 is about the max I think you can get out of a stock 951 internals before you need to flow the head and dump some major money into it.

I'm no expert but I'm just talking about dyno results that have been posted or that are on some vendors web sites, but again a dyno can be manipulated so this numbers may be correct....

300rwhp seems to come fairly easy with all the usual boltons people do.
A new turbo gets you another 20-30 or so easily.
Then these cars seem to hit a wall where people get lured into running higher and higher boost but even then they're lucky to make what, 345?

According to those dyno results it's very hard to brake 300rwhp

I'm just sayin'... I haven't seen it yet. ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
Remember, a stock 951 was rated for 225 HP at the crank. Minus 15% for drive train losses, and that's 191 at the wheels. If you get it up to 280 WHP, that's a 50% increase. That's HUGE.

Pauly. Your quite right 300hp ( crank ) is generally thought to be the limit off 26/6 which he made a 1 bar, dyno graph for it. He hasn't made 330 public so maybe I shouldn't off said anything. It's hybrid 26/6 not sure in what way. Same dyno shows most n/a cars around 150
My point was if philip77 want to get the most from his 26/6 then this could be optune.
This ecu has been avabile for around a year at least now.
Stage 2 kit which is Dpw and boost control and chip set is sold with claims off 320 hp on 26/8 300 on 26/6 however iv not seen someone get the full 320 once installed

Well, that ain't right! Here are runs from 6 different NA cars I've dyno'ed. Some are stock, some have mods. The high outlier is my race car, which has every legal racing trick thrown at it by both Vision Motorsports in CA and Michael Mount in MD. It's a very atypical 944 engine (and still doesn't break 150 WHP - which is actually good... because the 944 Cup limit is 145 WHP).
So, if your dyno runs cars 25% higher than reality, sure - 300 HP is easy to reach with bolt-ons!

Agree with Van. Chips and a larger exhaust isn't going to net anywhere near 300whp. Many dynos and vendors are selling dreams.

I know some people just will never believe it, but here's a thread with a 951 engine that has 10X more done to it than what we're talking about running 1.3 bar and making under 230HP crank on an engine dyno.
You can bolt on all the aftermarket stuff you want, but there's just no way to hit 300HP with the stock components

I'm taking crank hp not rear wheels. So there is off course room for error based on caulations used. My point was 150hp n/a at the fly and 300hp at the fly on turbo. However this only based on what iv read or been told not seen, so I'm not arguing I'm right
There's a uk dyno league not been up dated in a long time, not sure if all the cars where log on same dyno.

2.5 vw turbodiesel is making 300 flywheel hp with turbo and chip.
