Title: Re: best aspirated cam???? Post by: richie on July 16, 2012, 08:48:45 am FK48 on 108 lobe centers or FK89 for less maintenance on valve train
cheers richie Title: Re: best aspirated cam???? Post by: jamiep_jamiep on July 16, 2012, 15:55:29 pm I'd stick a 110 in there rich :) hahaha
how else am I going to get in front of you?! ;D Title: Re: best aspirated cam???? Post by: Fast Bug on July 16, 2012, 19:13:23 pm JPM Raptor and alu pushrods ;)
Title: Re: best aspirated cam???? Post by: JS on July 17, 2012, 22:46:41 pm Ask JPM! Nope, he would get the correct answer - not an opinion. Title: Re: best aspirated cam???? Post by: Erlend / bug66 on July 17, 2012, 22:54:37 pm My opinion is to ask JPM ;)
Title: Re: best aspirated cam???? Post by: stussyrich on July 17, 2012, 23:48:19 pm this was a suggestion.. custom grind .613 lift 320 duration on a 105 lobe center..
Title: Re: best aspirated cam???? Post by: Zach Gomulka on July 18, 2012, 02:57:07 am I was under the impression that the 86c was the next best thing behind the Raptor cams?
Title: Re: best aspirated cam???? Post by: SuperTrigger on July 18, 2012, 10:42:08 am FK46. :)
Almost same engine that you have exept lower compression (11.x:1) and 44 intake valves it made 195whp@6700rpm and 230NM (234hp/266Nm at engine). -Puide- Title: Re: best aspirated cam???? Post by: Jon on July 18, 2012, 13:31:32 pm I was under the impression that the 86c was the next best thing behind the Raptor cams? Whats "best"? ...more power or long life/silent valve train? Many cams are designed the modern way, but usually the power is lacking... JPM's cams have both... Title: Re: best aspirated cam???? Post by: stussyrich on July 18, 2012, 13:56:53 pm should have said it's for drag only so not bothered about long life or quiet valve train.
The lifter bores have bronze bushings and i'll be using tool steel lifters.. Title: Re: best aspirated cam???? Post by: TexasTom on July 18, 2012, 14:50:52 pm JPM Raptor and alu pushrods ;) Don't forget SINGLE springs! ;) TxT Title: Re: best aspirated cam???? Post by: Torben Alstrup on July 18, 2012, 18:20:22 pm I was under the impression that the 86c was the next best thing behind the Raptor cams? The 86C is a killer cam. But in an engine like that with 13+ - 1 CR better choices can be made. You dont build an engine like that an want to drive it on the street much...IŽd also say FK89 or the new 2290 (I think) from CB. if you are ready to step up to a Ratptor, that would most likely give you most HP, and definitely the lesser need for valve spring tension. T Title: Re: best aspirated cam???? Post by: Zach Gomulka on July 19, 2012, 02:02:53 am Thanks for the clarification, Torben. I've got a 2332 longblock that I hope to stab that cam in someday...
Title: Re: best aspirated cam???? Post by: Shag55 on July 19, 2012, 04:12:16 am Re: best aspirated cam I have a xr328 on a 106 and TP tool steel lifters. It was made for a Super Stock motor. It was on a 106 to help get out of the hole with such a big cam on a smaller motor. 240-250hp. With a big motor say 280 really no need for a tight lobe center. Title: Re: best aspirated cam???? Post by: Lids on August 07, 2012, 22:39:00 pm I had an 86C then went to the dark side and now have JPM
Title: Re: best aspirated cam???? Post by: Frallan on August 08, 2012, 01:40:35 am I had an 86C then went to the dark side and now have JPM Me too. ...and single springs from Crower.

Post by: BeetleBug on August 08, 2012, 10:34:15 am the lifter bores sleeved . the power come early and pull strong up 7500 rpm I know, I used one myselves in a alu case but luckily I got it out before it did any damages. |
