Congrats Ted....What is you power band like (5500 - 8500 rpm) ?

 

This car will make a dead man scream!

 

It's running pretty well, but there's more in it. I'm making a few adjustments and going back to log the difference.

 

get us some datalogs Ted! A video would be nice too!

 

I will post a writeup with a log and VDR graph as soon as I finish tweaking the 93 octane tuning. As of now, it's hovering at 560-570whp with goose eggs in the knock sum column, and there's more left in it. Needless to say, it spools and drives wonderfully.

 

what Rc is your Engine Ted?

Are you using a steel rod or aluminum rod?

 

I believe he is using Oliver steel rods and Venolia ceramic coated pistons. I am looking into the same setup for my build. Pretty impressive hitting 560whp on crappy pump gas. I am lucky to get 400 out of mine on pump. Good thing we have E85.

 

TwinScroll FTW!!!

 

The rods are Oliver billet 156mm.

Rc? Hmmm, not finding a definition for that in my mind.

 

Maybe he meant CR?...

 

Compression Ratio is technically abreviated as Rc according to Mr. Heywood.

 

Ah, I consider that to be SCr - static compression ratio. In my case, it's a measured 8.9-9.0:1.

 

Brings me to an interesting question.

Dynamic Compression being held the same... if you change your static compression ratio how does that effect the performance of the engine? What are the tradeoffs per say?

I'm sure you designed your cams to give you the DCr that you wanted. Thanks in advance.

Just finished reading this thread, great job Ted and you are a very patient person...! Looking forward to seeing your dyno results...

 

Don't let Ted fool you...he has e85 right down the road from his house.

Ted, you need to make the switch to Big Maps and e85. I just need to get the maptracer excel sheet to work with bigmaps and older versions of MS office.
