    Dynamic compression ratios DCR

    Added SVS 1 1/2 stepped to 1 5/8 Headers, same tune (in blue). Tried another tune as it had more timing and more injector %.(in red) As you can see it ran out of fuel again and sooner. Had to add a voltage booster to the fuel pump and it solved the problem. When it was all tuned, it made power...

    Dynamic compression ratios DCR

    sanguissaevus - Sorry, my cam was a 225/234, same lift as in my other post. My int valve closed at 44.5 degrees @.050 with the cam installed straight up. I ******** it 2, 3 and then 4 degrees. Ended up with sticking with 46.5 degrees. I couldnt tell any change. My cranking pressure held at...

    Dynamic compression ratios DCR

    I think the advertised gen2 comp ratio is 9.5:1. My combo for my old gen2 was 10.25:1 and was achieved by JM CNC Heads with a 80cc chamber, 4.020 bore, .040 gasket and the the piston .007 out of the block. Camshaft was a 228/234 @.050 with .587 int lift and .575 ex lift. Also had a set of SVS...

    Waterless Coolant

    I have used that coolant in my GTS for the past 5 years. The only thing that is a pain is that you have to get all of the existing coolant out. It was easy for me as the engine was out and the radiator was replaced too.

    Help identifing wing on GTS

    Fatboy18- Your wing was originally produced by Multi-axis Machine in Boyd,TX. The owner being Tony Wendling. The "wingman",Kingman Hitz, had the idea and was the club president here in DFW awhile back. They made a single plane wing and a dual plane wing. I know both of these wings were run on...

    Roe racing ported heads and 710 cam plus sct tune????

    Twister- Your car cranks over really slow, maybe time for a new battery before you start tuning on it! Your valve train noise does seem a tad on the loud side. In my experience, changing springs and pushrods won't add more noise. Have your shop recheck the pushrod length and lifter preload...

    Viper X10 On Track

    Great video and awesome driving skills! For those that have some track time under their belt, what is the durability of using 5th & 6th gears on a long, high speed straight? I had G-Force do the tranny in my gen2 and if I remember right, they said wide open runs in the overdrive clusters is not...

    Performance Gain Aftermarket Headers to Factory Tube Headers

    Yes the fuel pressure dropped quickly. I knew I was going to have fuel system problems but just not that early in the run. The voltage booster solved that problem. I never did check the pressure when the the booster was active. I wonder what it raises the fuel pressure to?

    Performance Gain Aftermarket Headers to Factory Tube Headers

    More proof that a well made set of headers work! My 97 GTS engine has JM CNC ported factory heads, crower shaft rockers, 10.25 comp ratio, 4.020 bore, stock stroke, 225/234 @ .050 cam and no intake port work. The first dyno sheet was with engine tuned with stock ex manifolds. First...

    650 NA RWHP

    The last engine I built with Greg Good Heads did 627whp/637wtq. You will need to do some serious work on the stock intake manifold to get your 650.
