T3/T4 Hybrid 60 trim too big?

[tomcat]

I just won a T3/T4 Hybrid 60 trim off of ebay and was wondering if that was going to be too big for the street What A/R do I need for a bike Most of the hybrids sold on Ebay are for cars.


I have approx. 175lbs compression. That is with flat top pistons and a .050 basegasket on this 1425 Kawi. I was told I shouldn't expect to be able to run a lot of boost with that combo.


I am not sure what turbo to put on this bike. The F40 Rayjay will fit under my fiberglass body better without cutting it up too bad, but I hear some negative things about them. I don't know what I should even put on this engine anyway. Let me try this, I will post the info of my engine and then maybe you guys can tell me what I need. I don't have a clue. My engine compression is approx. 175 lbs because we ended up putting flat top pistons to replace the higher compression pistons it had in it and also installed a .050 basegasket to lower the compression some. It is now a push start bike. Street legal with a 79 inch wheelbase. This info I am posting is what came on a CD with the bike so I am just cutting and pasting. here goes:

cutting the body is a fact of life ,, how much $ ,, if its too big for you (and not too small for me) I might be interested

[rajay]

The 60 is the compressor trim size. However you did not say what the compressor trim is. You can go to turbonetics.com and look at their compressor maps to see what you have. The maps are in pounds per minute so devide by .069 and this will give you cfm. The turbine A/R is what will determine your throttle response on the street. I use 1.5" headers (OD) with a Rajay EF60 on my street bike. Its the same set-up as your however, its a 4 valver. It build boost at 4,250 (about 75-80mph). the Rajay E flow flows about 44lbs per minute about 638cfm. The intake opening is aprox:52mm. You'll love the big engine on boost............

Hey Rayjay,


are you saying that you have to be running at least 75mph for it to build boost and come on

I might do just that. I have a buddy that might want it locally, but if he doesn't and it won't work for me, then I am cool with that.

The problem with cutting the body is that I can ride it now and my legs fit comfortably up against the body and when the turbo is on there my leg will be resting on the exhaust. If I had a narrower turbo I could make the exhaust elbow myself and could route it more forward.

[jackinzoar]

Vanson will add a "pot-holder" to your leathers , anywhere you need it

[Marc Powe]

Even with the Rajay your gonna have to cut the body for the exhaust. You can't put but so much of a bend on that pipe or you WILL choke the exhaust and it will cause your turbo to not spool up.


Jack said it the best.........cutting the body is a fact of life especially on a turbo using an aftermarket body. This why I use the old school nastalgia fiberglass body parts.....smileys/smiley1.gif

Rayjay,


You must be geared to the moon to go that fast in low gear.

[rajay]

Tomcat, no I'm geared too low for any real racing. My bike is a 5 speed 163mph @ 9,500 rpm. With this gearing I can cruise on the highway at 75-80mph...this is the high side. At 80mph in 5th gear its showing a good 3-5psi of boost. At 4,250 in 2nd gear, the S&S Super E carburates at its best. Get it up on the flat of the tire, point where you want to be and your their..................I must say, I have chose this 60 A/R so the bike runs well and this puts the big horsepower up top. The efi blow threw I'm working on is just the opposite. I have small 1.25 (ID) headers and a small 48A/R turbine. The new set-up is based on a Garrett T3/T4 H trim hybrid. The compressor A/R is 70. This set-up will be geared for the moon..............
