Boosted lt1, high compression and timing

Ditch the filter, or run a large/overkill one.

I bough the system 2 years ago but the guy I got it from had it for a few years but never actually ran it. So the filter is old but was never used.

@JOATMAN
Yep 500rwhp on 93 was my goal.

A couple more things in terms of Dyno numbers in general. The type of Dyno as well as SAE v. Standard correction makes a big difference. Also what elevation are you at?

What do you recommend?
The filter I have now is 4.6 at the base and 7 inches long and I would guess about 3.5 at the cones tip

Brute speed shows another 3.5 inch filter that has a base of 6 inches and length of 9 inches. I'd guess 4.5- 5 inches at the tip

Only other one is a 4 inch opening 9 inches long.

Since this is a road car I would think a filter would be smart?

I honestly dont know the answer to that.

I am pretty much at sea level

No worries, just trying to narrow things down. Dynojet vs. mustang dyno v. hub dyno v. mainline dyno will read higher or lower depending on which one it is. Also STD v. SAE correction will read higher or lower.

There are instances where if you're on one of these Dynos with a certain correction type, you could read 50-75whp different for the same exact car. Dynos are good for tuning but all people want to hear are numbers. This is why some dynos are known as "heart breakers." I do think your car should put down more based on the mods you outlined. I would get the fueling up to the lamba numbers Moe mentioned and work on the timing while keeping an eye on any knock as timing is increased as well as replace the air filter with a good flowing one (I used an amsoil one back in the day because I don't like oiled filters).

If you feel you get the fuel/timing on point with a good flowing filter and it still isn't near the numbers you expect, I would keep an eye on IATs and KR. Other than that, I would take the advice above regarding the restriction of the dual intercoolers.

Really depends on what you have room for. I know the SC side slinger stuff gets real tight on space. For ref the blue one is the one on my car. [ Flange ID 4, Top OD 5.25, Element Height 12]

Looks like I could try the 6 x 9 with the 3.5 flange with the room I have.
The 7 inch already very close to intercooler but I could angle a slightly larger one. If worse comes to worse I could test without one
