Hi, I'd like to know what kind of rwhp/tq can I expect out of a 1986 951 with chips, dual port wastegate, 3bar fuel pressure reg and a 3" exhaust without cat ?

Thank you !

Depends what PSI your running.. I have basically that setup at 17psi and zi think it's somewhere around 280hp

philip77o

280 whp or flywheel hp ? and you have k26/8 ?

Paulyy

anywhere from 250 to 280 rwhp and from 250 to 300 rwtq. depends on how good your turbo is, your engine condition, wastegate, tune ect.

eman930

That's Rwhp and yes that with a K26/8

Paulyy

You wont run the k26/6 past 15 psi. Just dies off to 11-12 psi to quickly.

Does it worth installing a turbo down pipe or it's a $400 to the trash ?

Paulyy

IMO Useless as the ID of the stock down pipe is the same as the ID of the turbine housing outlet.

MIT be worth giving this a go

I've got it on mine 26/8 running 1.3 bar and hold it to at 6k
I've got stage 2 intercooler Portland polished manifold and throttle body
80lb injectors
High flow fuel pump
Tial 38 Dpw
Apexi ebc
Map
Wide band

I've not dyno mine yet. A low speed roll start 10/100 in 10 secs

Tom made 330 hp on 26/6 at 1.1 bar but I think he only got 300 hp dyno sheet up.

Paulyy

how do you make 330 rwhp on a 26/6 when it doesn't even flow enough air to produce that power?

This web site is kinda awesome... How have I not heard of this ECU before... It's like Rouge Tuning on steroids

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.

eman930

Can you list the mods done?

Van

These were from 2010...

The green, technoduck's car, had quite a bit - certainly exhaust, chips, and so-on. I think he had a different turbo, too. I don't recall if he had the AFM or a MAF, thought.

The red was a 100% stock car.

And the blue was my turbo, which had chips, LBE and 3" straight pipe exhaust.

Paulyy

Just to note. When i had my k26/6. I had the following:
MBC
TiAL 38mm
Factory euro (no cat) exhaust
Huntley Racing chips
AFMLink piggy back (0 restriction to the turbo)
FMIC

I would get 15 psi @ 2800 rpm. My car would walk on a factory VZ Monaro from a roll at 80 km/h Even modified ones with cams ect. Just to put it in perspective how powerful my 952 was with the stock turbo.
