Mod Banshee Posted March 30, 2005 Report Posted March 30, 2005 What is the top end rpms on the rocket pipes? And what would be good gearing to run with these pipes I drag race 300ft and Tirl ride. Now I have 15/41 I was going to try 15/38 or 13/38 Quote
Ducman Posted March 30, 2005 Report Posted March 30, 2005 Here links to dyno's with Rockets dyno(Locogato11283 click) and (stclark816 click) Looks like Loco get max power at 8800 and signs off at around 10k, stclark gets max power at about 9k and signs off a little before 10K. Where it signs off is somewhat subjest to interpretation, I looked at it as the point were they dropped off 10 Hp from the point where they made max HP. Rockets dont seem to just hit a wall where they completely quit, they have pretty good over-rev. I have some differnt porting, tripple exhaust port, and dont make near as much HP as the clark boys but if I recall mine made max HP closer to 10k and signed off at almost 11k. mine had a big dip between 10 and 11 where the pipes almost seemed to come back on but not as much as when it was at max. I dont have the sheet siting right in front of me but I remember the dyno owner was supprised it reved so high. I have stock ignition with a +6 advance on the timing plate. I think a dyna or similar ignition would make a huge difference on mine and maybe get rid of the cammel hump at the top of the curve. Also consider my and locos motor are +4mm stroke, I think stclark may be as well. Rockets might make max HP at a slightly higher rpm on a 350 motor. Quote
locogato11283 Posted March 30, 2005 Report Posted March 30, 2005 my engine actually revs out to about 11,500. revs are gonna depend on more than just pipes. porting and other factors are involved. if you want rockets they will def out rev stock pipes. porting and carbs are a big determinant on gearing as well as pipes..

FIRST BANSHEE Posted April 2, 2005 Report Posted April 2, 2005 ok my mods are Rocket Pipes Cool Head wirh 20cc domes Bored 20 over Wiseco Pro Lite pistons Race Logic Superstock Porting 28mm Flat Side Carbs V-Force Delta 2s Boost Bottle Team Alba Clutch kit Hunson Clutch Basket Hinson Cushions Hinson Pressure Plate Lightened Flywheel Vitos Degree key Pro Flow Intake 6 Filtered air vents 20x11x9 Razr 2s 348458[/snapback] sounds like your running your airbox w/lid,those pipes will pull more air than your airbox can flow. yours probably won't rev as high. less air=less fuel=less power=less rpm. just my opinon Quote
Mod Banshee Posted April 2, 2005 Author Report Posted April 2, 2005 Yes I am runing my Air box but I think I will take off the lid. See I have to Run my Air Box Because I cross alot of water Holes Quote
