08 Busa mod Part 2 1441 motor

OK. It looks like it's time to build a 1441 with cams, ported head, and pistons. Problems with second gear meant I had to pull the motor and split the cases. It only seems logical to build it bigger and better since I'm in there. This is going to be a basic budget build. There is already another thread listing the mods up to this point. That one is loaded with BS. It was suggested that I start a new one.

At this point I have a few pics of the tear down. I have to upload a few more pics, but this is a start. Alan, Burke, and Joe stopped by yesterday to assist in dropping the engine.

you letting glyns guy do the portwork on the head? He does good work. I need to start a build thread myself, i gotta pull the head and put valve springs in, might as well do some drop in pistons and some headwork at the same time.

The trans parts are being sent to Carolina Cycles. They want 300 to race cut the gears. Shift forks are around 80.00 each. They are inspecting the other parts too.The head work and cams should be around 2000. I already have s/s Gen 1 valves and APE 65# springs. The JE pistons and block should be about 1000.00. I have to find a Gen 1 block. Gaskets should be around 150.00. Studs and nuts are around 150.

The port work itself is not costing that much. The cams and sprockets are a good chunk of it.

Carpenter, KWS, Vance & Hines(Freedom Motorsports), Ward, Star, Ace Performance (Sal down in Florida)....Lazer...all those are the best. Other honorable mentions that would be cheaper is Port Tech (Bill in Indy) and Competition Porting(this guy supposedly makes big power but from his work I have seen, I think he has Hellen Keller or Ray Charles doing the porting for him)

.385 Megacycle cams or maybe something in the .405" range would be good and still easy on springs.

I would like to see this thing make an honest 215hp on pump gas and on a regular street tire. It should go 8.80-8.90 on motor no problem. Maybe some 8.60-8.70s on squirt.

Should be fun. You're gonna make me have to fix my tranny and dial my hooptie in for the strip aren't you? I can't be building that is faster then my own...

Plans are for .415/.395 Webb cams. The MC cams seems a bit more aggressive than I'm looking for. 216 RWHP on pump would be sweet. I will probably tune it for the 36 hp shot first. 250hp is good for now.

They are on the list. I have been advised that they are not needed. I will go ahead and buy them though.

600+ h.p. pro street bike. Stock shift shafts. Bike never had a shifting or transmission failure. Bike went 7.26@ 197.45. 1/8 mile 4.82@ 162.39. Another one for ya... people buy lower case studs. Has anybody ever broke a stock lower case bolt? I see absolutely no problem buying or using them. I just question needing them. Good luck with the build. I put my hands on the multi stage. I have a stock cylinder but I'm trying to get my +3mm cylinder from Richie rich's house.
