Do post some specs and picks if possible... lots of interested folks on here, lots of mechanical know how and some race experience...

 

And a few curious folks that like to ask a lot of questions... :-X

If you don't care what the car looks like, smells like, and you

are not afraid to pick up a wrench -- $500 Porsche 944/924S are

relatively easy to come by.  I've got 4 of them :-)

 

2 became universal donors for the other two race cars

 

BTW, the conversion was pretty straight forward.

 

944 Turbos use Fuel Injectors that flow ~28% more fuel than their NA cousins.

 

We simply swapped the injectors, purged the fuel tank and lines and

both cars started right up.

 

On the first car we noted that the Lambda readings were spot on with

our uego and the exhaust ran cool enough to hold your hand behind it.

 

Like I said we haven't taken the car to the track yet -- but idle, uego readings,

unloaded throttle behavior has been very promising.

 

We're going to run with the O2 sensor feeding back to the DME as

well as a separate uego to monitor things.

 

We were not scientific pre E85 -- but we used to get about 10 gallons per hour.

Unfortunately that varied from track to track (how much WOT, accel, etc)

 

The 924S and 944 are both 2.5L 4Cyl Engines putting out ~160HP back in the day at the crankshaft.  The 924S has a 10.4:1 CR, I'm not exactly what the 944 has but it is close.

 

Race weight is probably 2600lbs wet.

 

keep the questions coming :-)

are all the other cars running e85?

 

If not, I'd think you'd have an advantage, other then needing extra fill ups due to increased fuel consumption.

 

If not all are running e85, I'd think that you could look for some sponsorship from the e85 dealership, or possibly their distributor, or the nearest ethanol plant...

 

Good publicity!

We are the only one running E85

 

We are sponsored for 2012 by White Energy, the largest ethanol producer in Texas.  They are expecting consolidation, so we'll be looking for a 2013 sponsor.

 

Since it is endurance racing -- we're figuring that any HP adv we get will be offset by the refueling time.

 

All types of cars are out there from Miatas to 5.0L Mustangs.

That Chump Series sounds like a really fun way to go racing!

 

 

If you are delivering enough fuel you should like your temps a lot better than with gas.

 

 

What fuel pumps are in those Porsche and did you get rid of the paper filters in favor of stainless yet?

These are supposed to be stock cars.

 

If not anything you do counts against your Value and your value has

to be below $500.  That is the whole car (not counting safety equipment) :-)

 

Don't think a new set of pistons will fall into that category.

Although shaving the heads might.......

 

Biggest thing is time and energy to do the engine swap....

 

Divorce isn't worth the extra HP in this series :-)

Great weekend -- car ran fantastic.

 

Only issue was a clogged fuel filter when we ran out of gas.

Probably sucked up debris from bottom of gas tank.

 

We didn't notice an appreciable increase in consumption.

Power was good.

 

2.99/gallon  vs $4 for premium (3.59 for 87)

Very good! 

 

Glad to hear about the power/torque increase (no shock, but glad to hear what we all know confirmed...), and very glad to hear that your fuel consumption was not an issue.

 

Do keep us informed as things go in the season.

 

Best of luck.

 

 

$2.99 vs $4.00...... more power with the cheaper fuel....  Hmmmm, let me think about that for a minute........ ;D ::)

 

Why more in the racing community are not figuring this out is beyond me.  It is up to a few enlighten ones to lead the way, literally...
