Hi,

I'm looking for some assurance or caution around throwing a complete Vortech Kit (V1, V2 or V3 non-aftercooled) on my car. Before replying, yes, I know running an aftercooler or intercooler would be safe-er.

However, what I'm looking for is evidence that I should or should not be concerned given that I'd use stock pulley (~8psi) and a conservative dyno tune.

Current relevant car info:

• 2001 4.6 2v, 102k miles
• Mobil 1 5w-30 every 5k miles since 20k miles
• Daily driven ~60 miles per day in Southern California
• Stock Internals
• Dragon 75mm Plenum / Accufab 75mm Throttle body
• Magnaflow Catted X
• SLP LMII catback
• FRPP 3.73's

Would I be able to pull off 370-380 RWHP with a safe tune without throwing a rod or any other concerns?
Thanks,
Wade

Well, kind of the same, but also completely different; my 98 has a v1 s-trim @ roughly 10.5lbs non-aftercooled. I've only owned the car since July but it's been supercharged for I think something like 6 years. It's not a DD and only has 10k miles or so on the SC setup.

But it runs awesome and hasn't blown up. It's got a completely custom tune and many non-vortech kit parts. Like 60lb injectors vs. whatever they provide. SCT 90mm MAF, in tank 255lph + external t-rex pump, etc...

Just go with their stock setup around 5/6lbs and get a tune. You won't pull 370-380 rwhp; probably closer to 330's.

Yes and no. Yes you can safely run a non intercooled supercharger although honestly you could spend another 1000 and piece together a kit off of CX racing and make more consistent power safely. But if all you want is non intercooled fun it won't kill your car but on 8lbs you won't be making 370-380rwhp. I made 395rwhp on around 10.5-11lbs which was a lot according to my tuner before installing an intercooler and haven't looked back. I would say you would make 350-360rwhp.

It's all in the tune. Run it fat and you'll be safe.

This is true.

Keep in mind, if you get your car tuned in the middle of the summer, and run it hard in the cold of winter, your "safe" summer tune may be "unsafe" in the winter. A supercharged car makes more boost when it is cold than when it is hot. I blew my motor (non-intercooled) in November at the dragstrip when the ambient temperature was 45 degrees, but my car was tuned in August when the ambient temp was in the 90s. In November the heat wasn't the issue (obviously), so I don't think an intercooler would have helped.
