Hi Guys

Heading to Ohio next Thursday for the Ohio Mile. First time to run the car since the record year in 2012 with all the rain and salt problems.

Just wanted to sincerely thank again all that contributed through the Go Fund Me account last year when we had to buy our 1200 dollar drive shaft ...

Nice fair and objective compare. Good job!

I'll keep you all posted as the first reman / upgrade engine goes together.

Just wanted to let folks know I have purchased a number of AAN cylinder heads, cranks and blocks and low wear high quality oil pumps. None of these items are left in the Audi repair parts networks.

I intend to build up a couple of 700 HP capable 3/4 block and head assemblies with the usual hardware ...

Hey All,

I am sure most of you have herd the depressing news that Speed Week 2015 was cancelled due to over mining of salt from flats. There was a huge exposed mud flow where the courses are normally set up.

It is undetermined at this point if there will be any way to salvage the fall World Finals ...

Jeff here,

Just wanted to provide a quick update and offer additional thanks to all of you who have contributed to the project monetarily and by words of encouragement.

REALLY appreciate and am very humbled by the support. Working hard to get it all together while keeping your motor projects ...

I big fat thank you to all of you so generously helping out!

Thanks to all my HP junkie brothers for the feed back / encouragement. I'll keep you posted on the rest of the car prep

Jeff G..

I am going to get back on this thread and get it finished very soon. Sorry for the long delay.

Tires are 15 X 25 Goodyear Front Runners. They are used pretty much universally on cars between 200 and 300 MPH

Oil Pumps, Pans and Crank Dampers.
This will be a short and easy post as it is a very straight forward part of the engine.

Oil pumps should always be disassembled and internal clearances and condition verified. Pumps can be perfect with very high miles or very imperfect at only moderate mileage ...

Just corrected typo on wrist pin length. 1.995 is the correct figure.

Pistons have a bevel at the top but the stock chamber overhangs the bore considerably on the sides and a little behind the exhaust valves. This varies slightly from head to head. Best practice, if you want to do the work yourself ...

Stock chamber volume is 45 to 46 cc's. These pistons have a positive deck height that requires that the
chamber be opened to the bore size. When doing this mod it is really smart to just go ahead and un - shroud around the valves as this is a substantial benefit to low and mid lift flow. The MLS ...

FRP Engineering is proud to announce our all new line of extreme performance Race ...

I'll be sure and add a series of pics before this article is finished.

Hi to all and please don't die of shock BC I am getting back to this so quickly! Promised I would !

In this installment we will build the lower end. This will be a little lengthy because it is so easy to make seemingly small mistakes that end up causing big problems or outright failure.

We have ...

Dear Carl

You don't want to plug the case vent - ever. The pressure is there from combustion pressure getting past the rings. It must be vented. You need a catch can with an oil vapor separator. 034 and others sell several of them.

Hey Guys. No there is no current Gates hi performance belt for our 5 bangers.
I would certainly by like 10 of them to start if you can get them to build it - assuming the price is reasonable..

You are all welcome. I'll get the next post done soon to keep this series moving. Happy T Day.

Hi All.

Sorry it has taken me so inexplicably and inexcusably long to get back to this. No excuses, just busy and tired at days end.

In the first segment we covered the initial stages of block preparation. I will continue with Boring , Honing, Cylinder Wall Finish,
Block Decking and Validating the ...

Absolutely.

That's awesome. What you are after with the model makes total sense to me now. Certainly the maximum BMEP force is at or near its maximum at 13 to 15 degrees after top dead center - IF the ignition timing is correct for the octane / burn speed of the fuel being used.

However the piston "weighs ...

Hi Chris

All interesting stuff but I am wondering if you are too deep in the forest here to see all of the trees?

Unless these models have values for dynamic combustion forces I think they are of somewhat limited benefit. When factory engineers set up a balancing paradigm they factor in the ...

Regarding lifter orientation within the lifter bore : They rotate constantly within the bore. Lobes are slightly offset and the lobe face has about .0005 of camber grind which works with the offset to insure they rotate. Hence no wear pattern. Bazzillions of lobe cycles spread over zillions of ...

Hi All.
Thanks for your patience on me getting back to you all on this. The facts reported here are not meant to be critical of anyone or any organization in our community - they are - just facts.

I have not gotten my data back from my camshaft consultant in California (he went on vacation) but I ...
