Seattle Tacoma guys

I need some advice on dyno time for my car. I've never done it before and would appreciate any advice on where to go and what to do. I've been working hard trying to sort out the problems. New injectors helped and I upgraded to a different firmware that gives me more resolution in pulse widths. Anyway, I have the car running really well now as far as I can tell so I might as well see what it will do.
From what I understand this is put up or shut up time so it should be interesting.

When the time comes I would be fun to have some of you guys come if possible.

Pay the extra money to have a WB used to sniff the tailpipe...


Chassis or inertia dyno??

DN,

Try and locate somebody who has a dyno that they can do steady state.

The Dynojets are OK for full pulls when your trying to do top end tuning.. but you need to hold steady state for tuning in between closed and wide open. Set the dyno with a load and hold 2000 RPM... then hold 2500...then hold 3000.

It will probably run you a few more dollars... but it will be well worth it.

Yes, please post the numbers when you've got 'em.

There is one in Kent that I have heard is good, don't use the one in Kirkland, bad bad place!
I'll show up if you give me a little notice and I'll hold your hand.

Sounds good, ive had a few car buddys go to the dyno in the kent area. They were very happy with the results (who wouldnt with 338rwhp). But i DO NOT GO TO CARBCONN IN KIRKLAND!!! bad bad place.

What is involved in a dyno and what are average rates? A local shop just added a dyno into the floor of their shop. I was thinking of using it to tune the carbs on the 2056 I'm building. Their rate is $90 and hour.

Mark D.

Let me know when your ready and I'll show up with you.

I have several cars I need to do pulls on (as long as your still in Napa)

90$ is kinda high right now. Most are at 70-80$

Brad,
Sounds good. I'll let you know. Gotta finish the engine first. Maybe I'll see if their interested in a group rate and we can do a club pull or something on a Saturday. That would be fun.

I got dyno time set up for Wednesdat May 28 @ 10 AM. Blood Enterprises in Auburn. O2 meter and steady state for tuning. Guess we'll see what it will do

I know, Blood Enterprises sounded menacing to me too. I'm not superstitious but I have to admit to some trepidation. I could understand Tears enterprises. I can imagine spilt tears but I hate to think of spilt blood.

Ok, I'll try to be there too. Blood Enterprises damn, that's Auburn for ya, everyone there still has a mullet hair style too.

That would be great. I'm not sure what to expect. The owner Graig said he could hit the cross points on the VE map and he could give me O2 information.

When the time gets closer I'll get in touch.

Like Brad said, you do a run at 2000 rpm then 2500 then 3000 rpms and so on. This is to readings at various points for reference,ie what the actual mix is (A/F)and hp + torque.
Full pulls and fun. Engine warmed up, holding 2000 rpms in 4th gear, dynoman drops his hand and you floor it to say 6000rpms. Repeat
Stop, get out and look at the print out to see what is going on. Pretty basic. Very loud.
I have done both kinds to figure out my car and what to set Mps's at. I need to do it again and adjust mine on the spot for better tuning.

If you have time and money... do the steady state pulls at 250 RPM increments (or whatever the resolution is with the MS)

Goeff..

New SuperFlow software showed up today for our dyno... we powered it on yesterday and ran thru some tests... Water tanks are next. We have finally moved all the cars out of the way so we can get to the tanks and stand them back up.

I have the dyno reserved at 10 AM Wednesday May 28. I don't know how long it will take but it would be fun to compare. You might want to call. The guy to talk to is Craig @ (253) 939-4121.

B- Cool, when did you pour the concrete?

What do you people think of the Redline Weber F/I system http://www.redlineweber.com/SEMA2002/fuel_injection.htm ? It was designed for an air-cooled VW motor. Do you think that it could be (easily) adapted to keep the d-jet intake runners? BTW, the buggy pictured on that page is featured in the June issue of Hot VWs ... it weighs 1100 pounds and has 132 hp at the rear wheels! I bet it's a blast to drive.
