Starting to get ready to finally start assembling the race car. I should have the last of the weight removal from the shell done this weekend. The next steps are a lot of welding - upgrading to the cage to Prod specs, weld all the seams, and build the frame for the fuel cell. After that it is get the primer on and paint the bottom and interior.

Been a little slow getting to this point, but I ran out of those two vital ingredients - time and money....

Can I get away with an 8 gallon fuel cell? That means 6MPG to cover 45 mile races (max).

The motor won't be very different from the IT version, so that can be the baseline.

I seem to get at least 6mpg, maybe up to 7-8... You're counting margin for those pace laps, etc, right?

That's why I'm asking the question. Don't know what mileage to expect. If I have to go to a 10 I will.

To put it in perspective, the GT1 car with the 310ci gets about 3.5MPG and dynos around 650HP. That would suggest that our relatively tiny motors with maybe 140HP should get more than twice that figure.

I was hoping it was one of those details you tracked!

It's hard to miss - but that's what I'm saying, I know we get AT LEAST 6. Recently did calcs for an enduro...

Then you need to use the right pedal more, not so much on the middle pedal...

If we were talking about airplanes, I'd say a constant 150 hp would burn about 9 gallons per hour.

Yeah, that does look like a fun track... good elevation changes, I trust?

It actually looks pretty similar to a track near here, called Grattan Raceway...

The only problem with Grattan, and the reason I don't race it (though I've done a fair bit of testing there, for work) is that front straight. Not only is it long (1/4 mile dragstrip), there's a huge hill leading up to turn 11. While we do have decent torque - when running with a mixed group of other classes with more powerful cars, all those guys you whizzed by in the turns go screaming by on the straight. It gets VERY frustrating.

Andy - refresh my memory, you guys are going full-prep EP, right? I have to admit, after reviewing the qual results from the Ruboffs, and seeing a lot of friends there, I'm once again tempted... though I think I would give up my big brakes and try LP FP, maybe. I'd just sell my car and build from scratch... Do you expect to be out with that thing next year? Also, did you see that 944S whuppin all those GT3 Cup cars in GT2??? Mind you, I'm still rooting for all Porsches; in fact, Scott Sanda is driving one of those GT3's. He used to be a 924 driver, in fact had (probably still has) a DP 933 he ran SPO with...

No way in hell will our car be competitive in EP. I'm going the FProd route. Still think the big brakes are - or should be - legal. They are FACTORY parts! I have great doubts as to FP competitiveness - not when the spridgets have the same HP and 500 less pounds.

I would like to petition the CRB to move it to GP, citing your data that moved it from ITA to ITB. The 'rule of thumb' is ITS to E, ITA to F, ITB to G, and ITC to H. So it "should" be a no-brainer to see that the car is really a G. But that makes it significantly heavier than anything else. OTOH, it is the second heaviest car in F... I know it will need some adjustment, but I won't have a voice until it gets on the track.

Mike Muren (GT2 944S) lives around the corner from me. Can't say he really put the hurt to the GT3s, but he did throw the win away. It would have been a really cool battle had they fought to the end.

Chima became the second Neohio driver to throw away a win in HProd.

The ASedan I work with is on pole - Tom Sloe in the "infamous yellow mustang" (#7). I'm really missing not being out there, but money dictates otherwise. When the Runoffs were here I could jump out to a customer if I had to - can't do that from KS.

Yeah, that massive weight is a real concern for me too. How are the other LP tin-tops doing? Anyone really having any luck?

I would consider doing full-prep in FP, as financially insane as that must be...

LP Prelude won EP. He gets to P&P the intake manifold and throttle body, which we don't. And an LP 240Z (or was it an RX7 - trying to remember what Thrash drives off the top of my head!) was second.

The Rabbit/Scirocco contingent had 2 podiums and another top 10 in GP.

Full Prep in F might work, as LP in G.
