Building high compression engine

y2k02 · February 4th, 2012, 09:01 PM

Yes I pretty much do all my own work. This is the build of my new shortblock. I pulled the engine that was running just fine and pushing my car into the 9's without 1200rwhp just to swap in some flattop pistons to really bump up the compression. My machine shop checked out my block and said it really needed to be bore a little. I already had the pistons I planned to use. So, I took them a fresh untouched teksid block. I went and picked it up along with the rotating assembly that was balanced.

WickedSnake00 · February 4th, 2012, 09:42 PM

Damn, flattops? That's got to put you in the 11:1 CR range.

What are you running for fuel? Going E85 for it?

y2k02 · February 4th, 2012, 10:04 PM

Been running E85 for 2 years now. It will be closer to 12:1. I was running 9.4:1.

p4ndiamond · February 4th, 2012, 10:20 PM

haha awesome. were almost doing the same thing huh. What brand rotating assembly you using Im going with a set of custom grind cams more than likely. im looking for a good 7500 rpm

y2k02 · February 4th, 2012, 10:35 PM

I'm using a forged cobra crankshaft and manley H-beam rods with arp 2000 bolts.
My cams are 232/230 .560/.560 with a 115lsa.

you will be pleased with what high cr and boost will give you, running c16 or methanol. running 32 psi at 12.5 cr on methanol and 572ci with shorties makes a wonderfull crackle lol

p4ndiamond · February 4th, 2012, 11:01 PM

GEE sus. thats some nasty lift. Can't wait to see it run. ui expect to be done mine in about 8-9 months.

y2k02 · February 4th, 2012, 11:30 PM

Mine will be running in under two weeks.

Scott2001GT · February 4th, 2012, 11:42 PM

Appoved man! Can't wait to see the spool difference

limited · February 4th, 2012, 11:45 PM

upping the size of turbo's?

y2k02 · February 4th, 2012, 11:54 PM

No, the 60's will support 1100fwhp and I don't plan to max them out. I figure the car should have no issue running deep 9's.

Scott, spooling was not an issue before. I'm sure they will spool even quicker.

Scott2001GT · February 5th, 2012, 12:13 AM

Spool so much faster

gofastralph · February 5th, 2012, 12:15 AM

Will you have to notch the piston? I built my engine with 10:1 pistons and was just wondering how much cam you can do before notching for the valves.

y2k02 · February 5th, 2012, 12:20 AM

No notches needed.

gofastralph · February 5th, 2012, 12:24 AM

Good to know, thanks man! Looking forward to following this build.

y2k02 · February 5th, 2012, 02:33 PM

Now I just need to file the rings. I've been waiting on rod bearings since 12/29/2011...
I may have to buy another set local to speed up my assembly.

saxmanJJ · February 5th, 2012, 03:24 PM

How much boost will you be throwing at it?

patrick60 · February 5th, 2012, 04:45 PM

So just a compression bump? No other changes ? I`m pretty sure i remember reading you street tune the car so i know we wont see dyno numbers of the diff the bump in compression made.

Looking forward to seeing some track times to see how much the bump in compression made

Very nice man
