full boost

[quattrorunner]

So last night I decided to just go ahead and install the .8 bar spring, not sure why I waited other than I've been shaking down the hot oil issue.
Anyway.......nice.
Now I get the comment popping a wheelie almost.
I have been watching the AFR because I only run one 044 pump and don't want to run out of fuel but .08 is still not too bad.
At first it was shocking so much that I had an upset stomach from the shear violence of the experience. Keep in mind that I use the 915 so gears are shorter and wilder feeling.
Anyway pretty fun.

Mine does that when i floor it from a dead stop. Feels like the front wheels are not even on the ground.

I have a 915-911sc with a 3.3turbo-k-7006-hks-aic-msd6al-sc cams-bb dual exhaust-blah-blah--rebuilt the trans. &3.3 engine at the same time..

Recently did a KEP-Stage 2 lighweight pp/clutch and andial intercooler.

I don't even bother with 1st and 2nd gear--I KNOW I WILL BREAK SOMETHING..

just leave it in 3rd gear--at 30+mph when i want to play/side by side roll.. .. The only thing i came up against a 69 camaro-little skiny tires in the front--stroked 500hp(he claimed)..raced from 30+40mph-and up..didn't want to do 2nd...I can tell u--the guy was gone when he floored it...

3rd-gear-at 60mph--downshifting from 4th is the "sweet spot".

I can no longer think about first but second is unreal! Third is a great gear too. I still think I'm under the 325lbft threashold for the 915(I hope). But it feels like a lot.
This car was fast at .45 bar, like hold it's own against newer performance cars like bmw335i etc. but now I feel like it's in another range, not sure yet what but dang.

Yup--boost is addictive..

I did race my friend with his 2012-bmw-335i-BMW with Tune-performance-at roll at approx. 3rd gear 40+mph..did it 4-5 times--he took the jump but reeled him in immediately..all of 4th-i think 117mph--5 car length--targa top off-had a passenger--he was solo.. This was with a stock clutch and stock intercooler..

Just changing to a lw clutch and intercooler does make a nice difference..But i think i want more... sooner or later have to upgrade to 996tt-territory--

My next purchase will be a 930 gearbox. I know I'm going to shred this little 915/61

[wjfk32]

I think u will need a short bell-housing--not sure and $$$$$.

[quattrorunner]

I know. Ouch. Maybe I'll just shuck it and then make a move.

[wjfk32]

Just drive nice and get that needle out your arm already....

[rsrfan]

Awesome Brandon. It's getting hot too. Just wait for January/February. Cold tires and cold air make things mighty interesting...

Well boys, I don't know. You and Walt are accustomed to a close ratio tranny and the explosive feel of it. Go to a stock 930 tranny and you might feel it was a step backwards - but then again, maybe not since finally you'll be able to use 1st and second gear.

I haven't driven a turbo powered 915, nor a G50, so really don't have any base of comparison. But I do like the tall legs of the 4 speed, especially 2nd and 3rd gears. It's pretty nice to not have to worry about grabbing 3rd until around 80.

[quattrorunner]

Yeah it's fun. It is getting up there in temps eh?

It is also nice to be able to run laps at the track and only have to make one shift/downshift per lap. The 4 speed box is cool in my book.

My car had that feeling too when I first bought it. I found it a little unnerving. When I checked my alignment I found that it had been set to 0 toe on the right rear wheel and +30 minutes toe on the left. Re-set the toe and this settled the car down.

Yes, but the best of both worlds is a shorter geared 930 box. It has the strength of the 930 box but lower gears to simulate the 915.
This is on my bucket list.

[quattrorunner]

A shirt bell housing 930 is like 4 915 transmissions. Brian bodart made one last like 5 years with more power.

[RarlyL8]

It's still going strong with the new owner.
Yank the 915, add the WEVO parts and it'll last if you keep the torque below 350 ft/lb and don't do any drag starts. I loved frying the tires in 2nd gear and did it as often as prudent. Went through several sets of 345 and 315mm tires over the 10 years I had it.

I have a 930 gear box with LSD and Andial 8:39 R&P and haven't been outta 2nd gear yet

Still breaking in my new motor. Boost tried to come in while I was seating the rings and it felt like all hell was breaking loose!!!

Boost pressure helps to seat the rings! You've done the cam run-in so now let it rip!

[quattrorunner]

Yeah, let that dog eat!
