    Finally got my car dynoed last weekend, and made 513/502 on my second of three runs (they lifted a little early on the first which was 512/502 and was trending to be higher), and the third was only 496/488 as it heat soaked badly. It appeared that the dyno was reading pretty conservative, as a few others that had had their cars run before on other dynos were much lower.

    Currently running Lund shelf tune, Ford 113 intake, VMP 2.5 blower pulley with matching idler pulley, 08 crank pulley, and flowmaster axle back. Trying to decide on what to do next to pump up the numbers. I don't want to do much other than bolt-ons, as the car is a low number production car and I want to keep it original/reversible if needed (not breaking open the block/heads, may look in to TVS upgrade down the road). I was thinking of getting bigger intake (JLT or PMAS) and VMP dual 67 TB with updated Lund tune, as well as looking in to HE upgrade (as plug and play as possible). I like the looks of the JLT much better (painted to match looks really nice), but I think the PMAS will make a little more power from what I have read. Does it sound like I am on the right track? Thoughts on which intake to go with? Anything you would do different based on my goals?

    Thanks,

    Jason

    An intake and throttle body will show modest gains with your stock supercharger. If you want a good boost in power, just go straight for the TVS. It's easier to replace than you think. As far as "saving" your car as a potential collectible, that's not happening anytime soon, if ever. There are much better investments.

    If you can afford the TVS blower, I would agree with @Catmonkey that it's a wiser mod for better power. You said you're considering it down the road anyway. Why not do it now and enjoy the increased power/torque. JMO.

    I should re-phrase, the TVS would be a long way down the road, don't have the money to put in to that now. TB and JLT is pretty much what is in the budget now, TVS with supporting mods is significantly higher cost, plus custom tune. Currently spread a little thin with the other project car.

    If you don't have the money right now, maybe way down the road like you said. As far as your original post, yes, you're on track with a good direction for now. And it won't break the bank.

    Have a plan with an end goal for the car & a budget.
    Purchases should work toward your end goal.
    Buying something now, only to replace it later, is a waste of money.

    That’s why we figured the TB and JLT were good items to grab because they can be used on the TVS, if I go that route. Right now I’d like to stick with the stock blower and just do what I can with it. Blower change is only a slight possibility, and a long way down the road if I even decide to do it. The car is plenty of fun as is, I just like to tinker.

    Just a follow up to the original question, thoughts on JLT 123 vs PMAS 120? I like the JLT looks much better than the PMAS, is the PMAS worth it from the standpoint of better power to sacrifice in the looks dept (from what I can tell it makes a little more, but not much). Pretty set on the VMP TB, seems like it would support what I have now and work with the blowers I may look at down the road.

    Think I'm just going to go with the JLT and VMP TB. The painted JLT just looks so much better than the PMAS. I have a feeling every time I will open the hood I'll regret the PMAS.

    I feel like fit and finish is better on the JLT. That said I went with a PMAS due to the sale team beefcake had awhile back.

    You might consider a heat exchanger upgrade and 170* thermostat in the mix as well, help manage heat and keep you running more consistent.
