914 gear chart?

[911st]

Can someone post or send me a gear ratio chart for a 914 with stock gears?

Thx.

If you want an excel spreadsheet you can plug things into, shoot me an email at gtgears@yahoo.com Be sure to put a title on it. Untitled emails end up in the junk trashcan...

I run c-f-m-s-x.
Nice set.

ExcellentKT! That will work.

Thanks everyone.

[trekkor]

You got it!

What motor are you running?

trekkor,
What are you running for tires? 22.5" is pretty small.

[911st]

I think most 205/50/15's are close to that size.

Would be nice to see a graph of stock gears. The table is a little harder to work.

Motor would be a 1.7.

Partially wondering if the gear splits are tighter than most stock 915's.

Still in the concept stage.

Thx.

For the past five years I had been running 205/50/15's, which are 23" tall.

Now I run 13" Goodyear radial slicks!
22x8x13 ( 225/45/13 front ) appr.
22.5x11x13 ( 305/33/13 rear ) appr.

22.5" tall!



It took quite a bit of work to make this happen.

You can use the chart I posted to suit your needs.
Just print it out and highlight your powerband RPM's on lines A-F-N-V-ZD ( stock ratios ).

My yellow highlights represent a full throttle run-up through the gears.
Each '+' before the start of the yellow swipe shows the RPM drop into the next gear after a 7300 RPM upshift.

For example: after an upshift from gear 'c' into gear 'f', results are 45 mph @7300 to 45 mph @5500.

KT,

Thx.

Fun car!

What TH times can you pull in your 914?

What motor/HP?

Stock gears?

[trekkor]

I matched my personal best a couple weeks ago, going easy. 2:15

I expect to hit a 2:07-10 in a couple weeks when I return on 12/11,12.

2.6 liter SIX, appr 200hp.

Gear set is c-f-m-s-x.


KT

[911st]

Looks sticky!

Sounds fun.

[trekkor]

Come to the track and have a ride along!


KT

[911st]

Thx for the offer.

What club do your run with?

Miss my 86 911. All stock except cat bypass, chip, and 7&9's with MPSC's. Last DE pulled a 2:16.5 at TH but had faster laps in practice.

2:07 would be fun.

Trying to come up with a plan for 2011.

The best.

Hooked On Driving in December.

12/2 at Sears
12/11,12 at TH

Come on out.
I have a second seat.

My 2:15 was with the two liter on 205's.
The Goodyear slicks are pretty nice.

Here's a fun video from nearly two years ago!

Send me your email addy. I'll get you a chart you can manipulate. I'll include a sample of your '86 911's 915 gearing at the same time.

Oh yeah, I remember now. You were talking about those wheels when I met you at Sears Point last month.
