Let me first say it's nothing special but I thought why not post anyways. I dyno'd my car over the weekend. The dyno was a Dynoje. I put down 222rwhp, and 256rwtq. Everything is stock K26/6, engine, etc. Only mods I had at the time were 3bar fpr, Guru v8 15psi chips, Blitz Dual SBC EBC set to 1bar. I'll post the dyno sheet in a day or 2. After 5.3k the AFR's dropped off the chart below 10:1, so I'd say there is another few hp and lb/ft there. I'm almost positive the 3 bar fpr was the problem, so I've switched back to stock. Not bad for a 194k mi 951 IMO.

After these minimal mods (chips, ebc) I would highly suggest anyone modding a 951 to start with these. Boost threshold is about 1000rpm lower than stock, and overall much more responsive than the stock setup. This makes for a much more pleasant driving experience.

You prolly have something going on cause 222rwhp sounds pretty low. You might have a few more hp on the table than you think. A bolt on 14psi chipped 951 I would think would be in the 240range on rwhp for the 26/6 cars. Eh in any case sounds like you had fun

take any pics??

Is the wastegate stock? You may be loosing boost. Were you able to map the boost aswell? I'd like to see how the boost map lined up with the AFR.

Yeah - he is dropping boost up high.

Shim the wastegate by 7mm.. you'll need longer bolts...

10:1 a/f up top means you are dropping a lot of boost.

Here is my dyno sheet from 2 years ago.

Red = BONE STOCK. No mods whatsoever. (cracks in exhaust around cat and muffler)
Blue = Guru 15psi chips, 3bar FPR, Reliaboost, and NO SHIMS on the wastegate.

That's just it, my 951 is basically stock. I have Guru 15psi chips and an EBC. Stock exhaust, stock AFM, stock wastegate, etc. I am dropping a good amount of boost on the top-end. After ~5-5.5k the boost drops from 1bar to ~.6-.7 bar. I think it's pretty decent for a basically stock 951 running more boost. I still have a Tial wastegate, SFR exhaust, Lindsey Maf and a few other things to put on soon.

A new wastegate should fix that since you have the EBC.

yea, shim/new wastegage and getting the cat out will make a world of difference.
