Tim, please use the quote feature. I think it would help make it easier for everybody to read your posts.

Anyhew...

As for the fuel pressure...this was determined using the gauge on Jim's car. If there is a problem with the gauge, I dont know.

So what injectors does he have on the car? Quite frankly it wasn't easy getting a straight story from Jim when I was trying to get the specs on the car prior to the dyno pulls.

In my original post I listed the modifications to this Turbo S...I thought you had read that and didn't feel it necesary to list the rest of the modifications again. Maybe I wasn't clear enough though. The Turbo S had guru chips (reliaboost, shimmed wastegate, 3 bar fpr) along with the Lindsey stage 1 intercooler. The car put down 270 lb/ft of torque.

There is nothing fishey. What I have noticed is that the dyno charts from the dynapack seem to be much peakier than those from a dynojet/mustang dyno.

I dont want to get into an argument about Jim's car. But the A/F plot at Deman's dyno clearly indicated a VERY dangerous lean condition at redline (Like I said, around 14.5:1). Geoffrey may have mistaken Jim's car for Ken's, I dont know I was 10 feet or more away from Jim's car.

Jim, maybe you could scan the dyno charts? If you cant post them, you can email them to me and I will post them.

 

I also want to state that I have a techedge wide band right on the dash. where I told the operator if it gets to lean to abort. It calculated a 12.5-12.9 on my third run at 5000 and above. It was rich below 4500 at 10.5. So should I trust his af witch was sitting 3" into a 4" exhaust or mine witch is placed next to the stock one.

 

Also Jim, I just remembered that you said the car dyno'ed at 350RWHP at Mustang Magic. Could you please post those dyno charts as well? I assume you had them get an a/f reading as well...so please post that too.

Back to the a/f curves...

John(wormhole)'s car had a decent a/f curve and his car had a 3" downpipe back exhaust, with I believe a 4" tip...so there goes that theory.

 

Look I don't want to get in a pissing match with you. But who hear could hit 161 mph in fourth gear.
I appreciate you for setting up the dyno date and for inviting me.
I have owned a 951 for over 12 years and have raced them for many as well. I can tell you for sure that 4th gear will not go passed 150mph. Because I use to be redlined in fourth at limerock.And bearly got over 140mph.

 

Are you able to scan and post the dyno charts?
I think that would help a lot.

If you feel there was an issue with the dyno, I think you should get in touch with Rick @ Deman and talk it over with him. If you decide to do this, please let me know what the conclusion is.

I would like to see a final resolution to this...

EDIT:
What kind of injectors are you running in the car, Jimbo?

 

andrew's s2 was on before jim's car, i remember we were going to leave after andrew's car but then we stayed to see what jim's car did because everyone was confused about what exactly was in it.

jim, your wideband and the dyno's a/f didnt match? did the mustang magic chart have a a/f that was similar to your wideband?

i dont have an a/f gauge yet and my printout was lean in the middle so i am just curious if everything is accurate.

also, just curious but assuming the dyno is accurate and my midrange is very lean should we have heard any detonation or is it not THAT bad, or am i just lucky so far?

i want to have my chips and everything corrected but i also want to make sure i am working with accurate numbers when i talk to danno@guru (or tim@sfr if after danno makes me new chips it isnt fixed, sorry tim but the guru chips came with the car and free is good!)

 

Anyone following this tread that was NOT at the dyno day should know, the guys that work at Deman are highly professional and very knowledgeable. I don’t think they have any problem operating a dyno machine, which is evident by the 800HP 911TT race car they built and tuned on the same machine. They were even nice enough to setup the video tapes of the 911 blowing by everything at the track, along with their 924 race car.

Timm’s car, the 300hp TurboS is a great example of one very clean, well maintained 951 that can make 300HP on a stock turbo with the right setup. Anyone who has never seen that before can then consider this a first, we were all there to witness it. Hell, even my car with a k26/6 pulled 307ft/lbs. It just goes to show the KKK series is capable of a little more then some are willing to admit. Once again beautiful car Timm.

Dan, I still need to look at the tape again to hear the noise you were talking about.

BTW.. I was having trouble uploading my chart, I’ll try again tonight.

 

Hi everyone,
I am getting the dyno charts scanned in, (my scanner died)& will post them this evening.
I have more to say but for now all I will say is if mine are wrong are everyones? Also for "something else done to the car?" what can you do thats worth anything much if you have a stock AFM????

Timm

 

Here are the charts for Ken Sumner's car.

Here are the specs, as he said:
"Stage 1 SFR turbo with #8 hot side

2.5" Bursh Test Pipe with custom 3" exhaust into Spintech muffler 3 inch inlet two 2.5 inch outlets

Auto Authority stage 2 chips

3 bar fuel pressure regulator

I found out on Sunday that my injectors may only be 35 the shop I use to deal with told me that they where 45 hmmm maybe that is why I am lean

KN open filter wide fire head gasket and race ware studs."

Jim, If you noticed Ken has the same 3.49 ratio plugged in and on the boost chart it shows 142mph @ 5854rpm.

Hey Adrial...the car with the 300HP and 260lbft, may be the dyno sheet was read backwards...260HP and 300lbft... which would be consistent with stage 2 chips for the 951S. I am bummed that you did not get to dyno your car with the SteveR chips...

OT: What is that ugly creature dancing around? Its not Barney since I think Barney has a tail...

 

Hi,
My car was the 300hp 89/951
If you haven't noticed I don't post much on the board but I do read...everyday for 2 years now.
I have nothing to gain by lying about what has been done to my car. I really don't care if anyone believes the dyno charts I did it because I thought would be fun & I was curious like most of us.I didn't think it would start a big disagreement.The car was bought about 2 years ago.I am the third owner,It had all the service records with it & Athority chips were the only modification done to the car.The car had a PPI
to confirm the condition.I want a reliable weekend car(it's not a daily driver) I could go anywhere in without problems that's why I didn't want major mods.I have been around cars all my life
I'm not a kid,I have a 24 yr old son that was born when I was 25 ..you do the math.I also have a 21 yr old & A 9 yr old.The 9 yr old keeps me young & so does the car.(He loves the car!)
I talked with Danno & he will post my charts & comment on them.
Here is the car:

89 951 55,000 miles
Guru chips/shims/FPR/reliaboost(adjustable)17psi
SFR ss cat back/stock cat
LR stage I IC
K&N filter(who cares) stock air box
stock AFM (forced air pipe ducted into the fender well form next to the brake cooling duct.
stock igintion
flowed & balanced stock injectors
ALWAYS run 94 octane pump fuel.
FAST & FUN !

Timm

Timm- are you the one who had the black car and the clear sidemarkers?

 

These are the charts of my run. A 3.49 ratio was also used.

Adrial, if you have free space can you post them as pics, Hobbystage doesn’t support it.

Yes,
clear sidemarkers & turn signals
