    Gen 4 & 5 Straight Line Performance from late 90s Viper without idle quality loss.

    I have been through a series of mods to my 1996 RT10 and would like to share some technical observations that may be helpful to those that would like to bring their late 90s Vipers up to gen 4-gen 5 straight line performance standards without sacrificing the cars drivability and idle...

    Gen 4 & 5 Performance Well Hidden, Greg Good Heads Dyno, 708 Cam Stock Improvement.

    Re: Gen 4 & 5 Performance Well Hidden, Greg Good Heads Dyno, 708 Cam Stock Improvemen No the CC 3051/3052 cam makes morepower than a 708 because its faster acting and produces more cylinder pressure.

    2001 Viper GTS Dyno Pull with minor bolt-ons :) (vid+pic of results)---

    I am shocked no one has replied to your post. 2001 vipers on average pull about 405-410 RWHP bone stock and 435-450 RWT. Your mods list is Smooth tubes (and filter I assume) = 6-10 RWHP Cat Back Exahust 10-15 RWHP No Cats is about 7-10 RWHP but you list high flow cats so about 4-6 RWHP is...

    Gen One and Gen Two Dodge Viper Camshaft Specifications 708 & Stock Gen One

    The lope mostly comes for the period of time when both the intake and exhaust valves are open (TDC) and how early the exhaust valve opens. Having both valves open at low speeds causes the engine a loss in flow control thus the rocky idle quality. Overlap = (intake .006 dur + exhaust .006...

    Gen One and Gen Two Dodge Viper Camshaft Specifications 708 & Stock Gen One

    After much research I went the conservative route. I do not want higher dynamic cylinder pressure than 8.0 to one (otherwise stated as about 185 psig cranking cyclinder pressure) on my 10.2 to one compression motor and I want the thing to have a low toned melodic rumble that is smooth at idle...

    Gen One and Gen Two Dodge Viper Camshaft Specifications 708 & Stock Gen One

    We have very long intake manifold runners and the late closing event on the intake lobe allows the long column of air that is still trying to get in the cylinder do so even after the piston starts back up the bore. If we had a short intake runner or a dual plane intake then the late IVC would...

    Greg Good Heads Dyno Results on a Gen One RT/10, Exhaust, Smooth Tubes & Filters

    ******************* Well I would highly recommend thin head gaskets and a milled Greg Good port job for the heads. If you want to stay NA then thats where the big jumps are found.

    Greg Good Heads Dyno Results on a Gen One RT/10, Exhaust, Smooth Tubes & Filters

    Greg told me two things when I was in his shop watching him rework my heads. When I showed him my stock gen one throttle body with its tiny 58mm blades and roughly 55mm conical reducing exit he said that TB is costing you at least 5 and maybe 10 hp. He also told me that if I wanted to get...

    Greg Good Heads Dyno Results on a Gen One RT/10, Exhaust, Smooth Tubes & Filters

    Thanks for all the comments guys. How rough is the 708 cam? I am thinking about a 708 cam when I fix my scratch in the cylinder wall but I am afraid of the car being very rough at 500 rpm. I want to end up with 180 psig cranking cylinder pressure (10-10.2) compression. High compression and...

    I recently had my gen one head gaskets go bad and decided if I was going to go through all this trouble I might as well have something to show for it.
