Colorado general chat...

Nice!
Looks like you had a good time! How was the cars setup?

Great. I made some minor shock adjustments compared to Pueblo because Hastings is very smooth, but overall the car was working extremely well.

Roland has everything right, Rieger splitter, yes it's a transponder, Motorsport Park Hastings.

Extremely fun track, lots of rhythm and some very technical parts to it. Also a couple of 'lift up your skirt' sections. Had to build speed up slowly in a couple spots, plenty of runoff but it had been raining a lot which meant plenty of mud if you got out too far off track.

The rieger splitter doesn't break unless you bounce it off of stuff. I'm going to build an aluminum splitter panel to fit in under the lip to support it and add some better front end aero, at some point.

Video coming soon... At least video of my fast lap.

... and is an ix ...

That's pretty much it.

[colorado_cabrio]

yeah ix is gonna be way slower; if you want to feel better run against my cabby sometime ;-)

I just can't believe that 200lbs makes that much of a difference. Prolly not even that with his sub in the back.

[colorado_cabrio]

I think it's the parasitic loss of the power across a much more complicated drivetrain vs just 200lbs of weight

[325ix]

I found this that says 8 compared to 7.6, decent ammount of time. However, I think lambo's car is pulling a hell of a lot faster than mine. I think it may be my poor ignition that is making it worse.

Can anyone confirm whether or not you can use 91 octane with the chip I posted?

[colorado_cabrio]

car then (0-60) , (1/4 mile)

1988 BMW 325iX 7.9 15.9
1988 BMW 325i Conv. 7.7 15.7
1989 BMW 325i 7.5 15.5

yeah my guess is the iX transmission has a significant parasitic power loss.

That it does. Viscous diff ftl. The iX is also driving 2 more axles through 2 more hubs and an additional diff. Of course it will have more loss.

This + ben's motor runs insanely strong.

[Roland H]

which just means you need to build your M20 to a 3.15L... :D

[clarkkey594]

This + ben's former motor runs insanely strong.

This is also true.

I seem to remember someone telling me NOT to do this way back when.....

unless you mean S52, in which case oh herro prease!

You never had an iX?

[Bimmerman325i]

Ah, yea.

S5x can swap in an iX, all you have to do is merge oilpans.
