Anything wrong with going NON-IC?

[shame302]

I'm considering installing a Vortech V2SQ i have had laying around. I figure i would rather use it vs. sell it. Its a complete non ic setup. Single focus pump is already in the tank. I wasn't going to install the kit without utilizing a FMIC, KB BAP (or cobra tank and dual pumps) and convert to bow-through but like i said, considering using it as it sits.

It's 99% just a street/cruise car but i do like to "use" it.

Is there anything wrong with installing the non-ic kit, having it tuned and calling it "good"? I have no HP goals or expectations really. If it picks up 50hp I'd be happy.

I think you should be fine. I mean there are some kits that dont come with FMICs,,

The tuner i plan on using is notorious for being picky, taking his time and tuning for drive-ability though he is pricey. He is expensive but i believe well worth it. If a car doesn't look like it's set up correctly he won't even tune it (unlike some other shops up this way).

Temps don't get too high up here. Summers highs rarely get into the 100s. Still, I'm concerned with the compressed air temps.

Ah,
No, the vortech kit i have is a draw through setup. I originally was going to wait, hold off until i could pick up a blow-through MAF and a fmic and shoot for around 420 RWHP but the car budget is small this year as things are still repulsively slow around here. Just hoping to safely utilize the kit make some noise under the hood rather than let it collect dust. It's a dog now (stock mach 1-ish #s), and I'm not out racing anybody so I'm not wicked concerned with laying down any particular figure but i want to use the blower and be "safe".

[shame302]

I'm fairly certain they are separate in my setup but until i have the car back from storage i can't say for sure. As far as drive-ability what can i expect from draw through?

(also, i just realize I'm in the wrong section, my bad)

Why not? what can i expect from drive-ability and draw-through? It ran great on the 2V/auto before.

[shame302]

Anybody had drive-ability issues with non ic/draw through?

FWIW i have the stock MAF now, stocker and mafia, 03-04 cobra maf and the unit the vortech came with.

I run a blow-thru (stock MAF w/ MAF.ia) and have ZERO drive ability issues.

I have a quick question along this threads subject. This question is also what I understand may be the issue with the draw thru setups. If the draw thru measures ALL air coming in, how does it account for the air not used?

What air isnt used?

[Furinox]

draw through will be fine at low boost.

air is recirculated via BPV

I’ve literally seen dozens (may hundreds) of non IC Vortech installs with a draw thru MAF and all ran perfect after tuned. Some are high boost race gas cars.

My tuner runs mid 8's with no intercooler, but that's due to class restrictions...

It seems you can get away with a lot more non IC with a centrifugal compared to a turbo. I have a friend with a 04 Mach 1 with a T-trim that runs 10.50's on 93 octane with alcohol injection. Its been that way for years and it runs perfect as a street car.

Yep, turbos generally do run higher IATs than centri's. Not to say centri's run cool by any means. The gradual boost building probably helps too.

Dave runs Drag Radial now with a BIG intercooler!

True, but it's not a blower anymore either LOL. I should have said RAN mid 8's with no intercooler. I believe he's hit 7's now?

[04azuremach]

Yep... you have to cut back fuel when you run meth, so if the meth nozzle gets clogged you're going to run lean. Lean + hot IAT's + advanced timing for meth that isn't there = invest in new motor. I run a blow through setup and intercooler and definitely recommend them for a street car. I am also saying it's possible to do blow through non IC. The risks are a little higher though.

If you have a moderate to high boost application with a draw thru MAF, you will have drivability issues.

Okay but what "kind" of drivability issues? What exactly does that mean?

I just would like to make use of the blower now, and later on ad in the FMIC and possibly blow-through. "Low" boost, don't care what it makes for power. I just don't want it to spit a rod out just because i didn't use an IC.

There's a chance it could run inconsistently powerwise, possibly even stall out in rare cases.
