There were a LOT of people and some great cars there! You're right, the 968 looks amazing! Ian I love your 89 Turbo, who else there had that black one? Excellent pics thanks a lot for letting us see them!! [selecting 5 stars for Ian]

Yes, there was a great turnout! Hats off to Skip for organizing the event. He was also generous enough to offer some great door prizes from Paragon Products. One of the other black 951's belongs to the owner of the dyno shop. I believe he's turning it into a track car.

GRrrr, I should have been there. Oh well, I'm just thinkin "spring getogether".

Here's me [scared as hell!] It took ~7 seconds to get from 6k to 7k RPM's!!!



My thanks to everyone who dyno'd higher than me... let's see... how many is that... oh, EVERYONE!!! Ah well... Not too bad... 143HP and 158TQ to the wheels. Stock numbers are roughly 133HP and 137TQ (89na) and 118HP and 113TQ (83-87na)[using 17.5% drivetrain loss].

Will have a full article and many more pictures up at Tech-Session soon.

I think everyone went home happy with the results, even if only to know what next to work on. The air/fuel metering comparison was a real eye-opener for some

My greatest thanks to all who came out... I think the count was 12 cars on the dyno in 5.5 hours. If you missed brews after at the Redhook, we'll have a go again soon via a dedicated Seattle Beer Night.

[Anyone attending that has pictures, please send them to me or send me the URL of their location and I'll try to get some of them up on the site also.]

Yes, Dyno's are VERY stressful! Especially when your car won't hold an idle after the third run

Hey Skip, I was about to make almost the same type of front chin as you have on your car (although I was planning on making the rivets less conspicuous). Did you make that or did you buy it? If you made it, care to gimme a couple hints?? Thanks. Also, where can I get my hands on a couple of those triangular KONI decals (Porsches have decals, not stickers) I wanted to place a one on each side of the car in a tasteful area, say on the front valencse (a la you) or aft of the front wheel arches. I dunno if it will look too ricy though. TIA.

Oh yeah, assuming 17.5% loss (I thought it was 15%), wouldnt the 83-87 cars have ~124 hp @ the wheels??

Danno

<ol type="1">[*]147hp * 17.5% = 25.725hp[*]147hp - 25.725hp = 121.275hp[/list=a]

or...

But from the many people who've posted 125rwhp with the 147hp 944NA cars, drivetrain loss is probably close to 15%:

Jason @ Paragon Products

Matt, email me your address and I'll send you some Koni decals and other assorted Koni goodies.

So Skip, I guess your near 0 restriction exhaust worked out for ya?

I thought you were going to go the Flowmaster route as well?

I am curious as the exhaust goodie selection these days is rather large and my shopping list is still empty!

Skip

Yeah, the drivetrain loss is one of the most vague calculations on these cars (except for how long it takes to remove the %^#$@ snap ring ). Everytime I ask, I get "between 15-20%"... though, Danno's right...most folks prefer the 15% figure (maybe we're being ambitious). I just split it down the center... plus, it makes me feel better about the money I've spent on *worthwhile* upgrades

I have aftermarket wheels that weigh 1/2lb more than stock PD's, and Kumho's in 245/45-16... every increase in rotational mass bumps the figure a bit higher... not sure there's a good mathematical way to figure this, because we really don't know the starting figures or rotational masses. Danno, is this in your "great big book of everything"?

I think the others in witness of my "near 0 restriction exhaust" would say it has one drawback. DEAFNESS! WHAT? I SAID... DEAFNESS!!! Yup, it worked out great... much better than expected... and under budget at that. My neighbors, fellow autocrossers, and wife especially appreciate the new tone (very subdued until you go WOT, especially with the cat)

[quote]<strong>I thought you were going to go the Flowmaster route as well? </strong><hr></blockquote>

I was, but got schooled on the na backpressure urban legend. Since this car is being prepared for club race, I need the mid and high RPM power more than the low. Not too sure where the middle is, but I can say that my setup feels strongest above 3k, but lost absolutely nothing below it... probably even gained there. (I'd love so much to see a stock 89 curve... the torque figures I got were more than expected, and never seemed low in the lower RPM's) Is this exhaust the 8v na holy grail? Maybe, I think the only way to be sure would be to use the MSDS and Stahl headers with the same header-back system I have. I can't imagine it'd get much better. My A/F was right on... went a little rich at the end (&gt;6k) but I attribute that to the AFM, Throttle, and Intake restrictions (which I can't do much about for ITS). The important thing was my mixture at max power... and that was great!

I'll have the full details up in short time, but the exhaust is as follows:
- Bursch header
- custom 2.5" mid-pipes - one with a Catco Cat, the other with a Dynomax UltraFlo Bullet Muffler
- custom 2.5" cat-back - Dynomax UltraFlo Oval, offset in/center out (brings the input closer to the tranny-side CV, so you can run it real close)

If you haven't seen the Dynomax UltraFlo specs, see their site. They "claim" better flows than any others out there... I find it very believable, and am completely satisfied so far.

Skipper, where did you come across that front lip?? Is it DIY-able?

Skip

Boeing Surplus, Renton, WA - 4x8 sheet of 1/8" black ABS - ~$13 ...cut lengthwise to 2.5", use 2 layers, fit to car, drill holes every 5-8", use aluminum or other rust resistant nuts and bolts to secure. I also used rubber washer to allow more flex. I ran with a single layer and it broke too easily... doubled-up I was able to mow a few cones, wife ran into the spare tire, and it's still holding up. If you want something a bit better, Boeing also sells sheets of 3/16" & 1/4" Lexan... for a nominal fee of course.

While you might think it does something useful aerodynamically, it's really there to hold my damaged lower lip together, and keep cones from going under the car. The screws are purposely visible to further identify my "who cares what it looks like" character
