    is a 100 shot safe on my motor?

    Lets get a few things straight. A 100 HP shot will give you 100 HP at the flywheel not the rear wheels. A 100 HP shot will give you 150 increase in torque at 3500 RPM and 131 at 4000 RPM at the flywheel. In other words the lower you start the nitrous the higher the torque increase. Computer...

    Rebuild/compression ?

    If you run stock heads and cams with a true 9.0:1 cr you should have no problems

    Rebuild/compression ?

    "Low" is a relative term. Since he has not answered the question of what cams he wants to run. Means I do not know the IVC, it is hard to say how bad low RPM performance will be hurt.

    Rebuild/compression ?

    What cams are you planing on running? Are you / he up for using the stock cams in the 9.0:1 engine and then changing cams when the blower is added?

    12s how do i get there?

    What do you call a small shot. I would say he will need between 75 HP and 100 HP shot depending on what else he does and how traction is. I use every 100lbs you lose is worth .1 second

    clutch or gears?

    X2 As parrish50 said if you are having no problems with your present clutch there is no need to change it

    clutch or worn synchros?

    Some questions 1) are you sure that the clutch pedal is on the floor when shifting (I know -- but I have seen people set the seat to wheel distance and then cannot push the clutch to the floor) 2) If you do not have your foot on the gas how far off of the floor is the clutch before the car...

    Car has no low end torque after PI swap

    Still sounds like cam timing to me. A quick way to tell if the cam phasing is out is to do a compression test of both banks.

    Car has no low end torque after PI swap

    X2 I had to edit this and ask. Why if the vehicle was running so bad would take it to the track and race it?

    Rear End Questions

    YES such an install require the same expertise as a gear install. The pinion depth should not change. But the backlash and gear position need to be the same as before after changing the carrier.

    4V pocket porting

    To compare your numbers to other peoples number they have to have been flowed at the same depression, normally 28 inches of water. What bore size were they flowed with, for modular normally 3.57 inches. Then were the exhaust flowed with or without a pipe. Either method is fine but the with a...

    Opinion on my compression ratio for PD boost

    One of the difference between a thicker head gasket and more dish in the piston is the amount of piston to head clearance or squish. You normally want to run more clearance in a boosted motor than a N/A motor, but this does depend on the amount of boost.

    4V pocket porting

    Without before and after numbers you do not know what has happened at different lifts. Did it improve at high lift and hurt low lift? Improve low lift and hurt high lift? Is most of the improvement at a valve lift past what your cams will lift the valve. What happened to the velocity in the bowl...

    Without before and after flow testing there is no way to tell if the changes helped or hurt.

    Question about an older dyno

    At what RPM's were the 271 rwhp and 323 rwtq and 321 rwhp, 374 lb/ft. Even better would be to post the dyno sheets.
