You're already quick and getting quicker so I wouldn't bet against it. An optimal alignment and that weight loss should help a bit too. Will be great losing that aircon. Just take care to leave its (stupidly heavy) mounting bracket in place so as to still comply. Maybe I should see if Quality Motors are happy to gut the cats for another 5 or so hp? Their labour rates can't be beaten.

I may yet change my mind but I also don't think super grippy pads assist ultimate lap times on cars as light and softly suspended as our Integras. They do have their uses battling for a corner but all or nearly all the fastest Black Beauty PB laps were set with failing brakes. Smoother, gentler transitions on closer to standard pads are probably more beneficial for time attack with these cars.

We will find out soon as I'll run TRW pads at the BBQ meet. I'm not sure who else is keen to go.

Most likely, the guy I sold it to sent me a photo of it lined up with his other classic. Looked like it wasn't going to be driven much. I got that car at 10 years old and 25000k's. No roof, no wiper, no badge and Mercedes Brilliant silver paint. The service history was interesting. It had yearly services with no miles added. The guy who bought it new pretty much kept it underground at Gillies and each year they jacked it up, exercised the shocks, squirted oil in the bores and a few other no doubt factory recommended procedures for long term storage cars. I put 10,000k's on it in three years and felt guilty about every one of them. It had to go. I Couldn't handle the pressure. Maybe some one can look up the plate and see what it's done now?

44400 in Aug 2014 so around 47k now...

Last record on CarJam was 8/14. It had 44,376km then and was averaging 5km/day over the previous 4 years.

Some very cool cars achieving $big. Some (see foto #12) under used - can't understand owning this & not driving it. Only 300 km/yr is nuts...

So Macca, we should stop going to the other side of Whangarei to full up with Gull 98 then?

I read about this and spent the summer on BP95 as the only 98 in Northland is Gull 10% ethanol blended.

Better safe than sorry I reckon.

Any researched opinions on running 996/997.1 engines on 95? Max available in a few NZ regions.

When I first got my car Doug I researched this thoroughly (enough to have once known the difference between brands and the switching dates between their winter and summer fuel blends in NZ) but am now drawing on memory here.

The Mezger (or GT1 derived for Macca) engined cars are fine on 95 when stock. If they are tuned/flashed for 98, then I'd always look to have them on 98 (with 997.1 Mezgers and up fine with e10 I think?) or on 95 topped up with an appropriate dose of a good octane booster like Nulon. Toluene is reportedly a very good booster too but is not road approved, reportedly as it's untaxed.

My tuner has assured me that factory knock control remains in place but I just figure why not feed her what she likes best.

No idea on the 'integrated dry sump' 996/997.1 engines sorry.

Here is the genesis of a new project

Walt I think you are correct (nice catch on the GT1/Mezger definition by the way!). My 993 is tuned for 98 and doesn't run knock sensors any longer as the factory ones are not compatible resolution wiping the Link G4. I therefore will choose Gull 98 over BP95 for that car as it has fresh head gaskets during the cam chance in Viton compound (better for ethanol blend). If caught short I have a nulon Pro Strength in the trunk which will give me a tank blended range. The GT3 is a modern DFI engine and the manual says its build with E10 in mind so I'm fine with E10 with that but will always prefer BP/Mobil 98 if it's available. The car is safe to run on the road with 95/96 as it retains factory knock sensors but I'd never run it on the track using 95/96 without an octane booster. For the track I think it's much more important to have a higher octane level. I used to run the 993 on avgas blend (it has no cat converters) around 30-50% 104 mixed with 98 and it ran really nice. Octane helps head temps as you know. I ran my DRZ400 here on avgas blend it's whole life and it made great power.

This is from Marcus Buehler who made all my CF parts in Germany. He does a full range of 964 parts too...

So do you think there is any risk of me running my M97 stock 3.4 on 95 when nothing else is available. I don't mind being down on power. To me in my ignorance it feels safer than 98E10. In regions with 98 I always run BP98.

Planning on running with 95 without octane booster in the SITT and driving 7/10 at the track due to not being track setup.

Macca

On the road no problem. Your car is built to run on 95/6. You will notice little difference when chasing 993s on Nirrhland back roads ;-). On the track over to you. This is where the engine is operating in its highest rev range for longest. It could be a hot March. If it were me I'd be using an octane booster on track just for the added security.
