wildbansheeboy Posted November 12, 2007 Report Share Posted November 12, 2007 I just have a few ?'s about long rods I have just got a new banshee and and thinking about building a 2nd drag shee but need to keep it under 350cc. I also have a 2ND set of A&S ported cylinders for a stock stroke crank .I would like to know if I put a +5 long rod in it will this affect my port timing if yes can I run a stroker plate with stock pistons to make the port timing right ?

Yes it will change the timing but not much. I can get exact figures tomorrow but if you really want things to stay exactly the same, you may want to take a hair off the thickness of the spacer and comp that in the squish. maybe someone else want to run the numbers but it would help to know your timing now or port heights.

wildbansheeboy Posted November 12, 2007 Author Report Share Posted November 12, 2007 (edited) not sure what my port height is. Are you saying that its a good idea to run the plate with stock pistons( pin height) over stroker pistons with out a plate?

Are you saying that its a good idea to run the plate with stock pistons( pin height) over stroker pistons with out a plate? I would have to guess on your timing but I will bet things will be fine by running 795s and no plate. I will also check the numbers on piston acceleration as that will be something to look at.

Dave I. Posted November 12, 2007 Report Share Posted November 12, 2007 I think there was a post similar to this not too long ago.....i think wiseco makes a piston for stock stroke but long rod. Im not positive on that though. Quote Link to comment Share on other sites More sharing options...

Im not positive on that though. Yea they are the 795 Series Pistons. 795's are not stroker pistons. They are made for a the long rod cranks both stock stroke and stroker. Long rod stock stroke = thow the 795 pistons in and be good to go. Long rod stroker crank = 795 series pistons, and run ethire a 2 mm spacer plate, or run stroker domes. Stock Rod stock stroke = run regular banshee pistons. stock rod, stroker crank = run regular banshee pistons, and ethire a 2 mm spacer plate or stroker domes. josh Quote Link to comment Share on other sites More sharing options...
wildbansheeboy Posted November 13, 2007 Author Report Share Posted November 13, 2007 thanks guys what is the ideal compression for drag racing Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted November 14, 2007 Report Share Posted November 14, 2007 Most people that run straight race fuel or methanol shoot for 175-185 ball park. Quote Link to comment Share on other sites More sharing options...
toyotaman Posted November 14, 2007 Report Share Posted November 14, 2007 hey i gotta quick question, i dont understand the whole stroker thing and long rod. is there some place around here that explanis that. also how would you benifit from the 5 mill long rod rods? just curious?

The longer rod makes the angle of the conecting rod to the wrist pin smaller. That makes less side to side load on the piston skirts.

wildbansheeboy Posted November 14, 2007 Author Report Share Posted November 14, 2007 (edited) I run 180psi in my drag shee but I have talked with two other drag shee racers at the track and one says he's at 130psi and the other one is at 145psi and both these guys run stronger then me most of the time. my times on a 300ft sand track is in the 4.4-4.6 range I am told that when you run over 150psi you start losing top end is this true? This info will help when building my new motor and tuning my other shee. Edited November 14, 2007 by wildbansheeboy Quote Link to comment Share on other sites More sharing options...
