OH MY, OMG,(IMG:style_emoticons/default/wacko.gif)
Had the first test drive in the 3.0 SC turbo engined 914 this morning, I could not evaluate the event as the short gears in the tranny left me no time to check more than one gauge at a time, It feels like I have 4 first gears. 4000 to 6500 only takes a split second on boost and everything is quite exciting at that point. One run I looked at the tach, the other the boost the next the a/r, I am unable to manage much of a look at any of them because I have my hands full just keeping up with the driving duties. I have to take the short gear tranny out as it will not work with this set up, it worked great with the stock 3.0 because the RPM's had time to climb now it does not, once I hit boost I had shift as it's at redline in a split second.
I will stick the stock geared tranny in and deal with swapping out the Quaffe LSD out of the short geared tranny later. Back to the garage.
Oh ya one more thing to add, the car is an absolute monster.

Sounds like loads of fun. (IMG:style_emoticons/default/smile.gif)

If you need more time to see what's going on at a particular load/rpm you can always use the "left-foot dyno". When I was doing the PEFI tuning on my litle -4 I would floor it and use the brakes (4x vented) to hold 2k-rpm for a few seconds while I checked a/f then let it up to 3k-rpm, hold with brake & check again, then 4k, 5k, 6k. Was also good for programming in my advance curve. If the rpm's are climbing you can't tell for sure what's happening when.

Yes I know this is hard on brakes, but pads are cheaper than dyno time. It'll be hard to hold back your turbo 3.0, but at the very least it'll give you a little extra time to see what's happening.

You have a cool project. Don't get a face cramp from that bionic grin. (IMG:style_emoticons/default/wink.gif)

You need another set of eyes on your drives, get someone who wll read gauges. Have them note egt vs rpm vs a/f vs boost etc.....We tuned my friends 900hp 935 clone in this fashion at Watkins glen (IMG:style_emoticons/default/unsure.gif)

A passenger could help keep an eye on whats happening. Or capture everything on a high speed camera to review at a later time. Theres just not enough time to figure out what had just happened on boost. I'm going to have to go for the tranny swap.
Just try to think how it would be with all 4 gears as fast as first gear.
I could try it in 5th if I found a clear stretch hyway.

A second person is the only way to fly...

Besides the added weight helps slow the car down a little. Oh, you could hold the ebrake on.. That might work..

Dont know.. I'd say dyno it.


I wanna see some numbers!!!!!

Congrats!

Paul I've been meaning to call you, I think an article on your car, Richs alien car, and mine would make a nice story all black 914's all with a different twist on power plants, your V6, Richs 928 and my 3.0 turbo, all Minnesota grown.
I put up a vote last fall to the club members, get a nice paint job or to turbo the engine. The turbo won.
Your car is beautiful, Rich and I have the rough around the edges cars but I think all of us are proud owners of our projects.
I would love to head out to see the progress you have made. Let me get that other tranny in this week and find out the source of my breather area oil leak
and I will give you a call.

Wow! That is nice. Are you planning to add an intercooler at some time? I know I'm not alone in begging you to put together some driving videos for the rest of us to enjoy. Good Work!!!!

Love the pics! The installation looks super clean. (IMG:style_emoticons/default/smilie_pokal.gif)

And, since I'm hooked on turbos, any info on any front is Officially Interesting™!

Glad to hear the test drive went well.

I dont plan on running anymore than 8lbs of boost at this time so I wouldnt gain anything by adding an intercooler, the 901 will be pushed to the limits with me running 8lbs. and my test today opened my eyes pretty wide I ran out of 4th gear awful fast, if I had thrown it into 5th with the pedal to the floor I would of found my cars top end in a flash . Its nothing like the 3.0 over 3500 rpms.
