Idle RPM??

[LETHAL GTS]

What are your cars idling at.
My car idles at 600 RPM. I thought it seemed low.
My local dealer says that's normal.
I think they say that because they don't know. At least thats the impression I got from the service writer.
What do you guys know?
It runs fine at 600 RPM.
Also, would the smooth tubes from a newer ACR fit my 94 RT/10.
I have smooth tubes now that I made and work fine. They just don't look as good as I think the factory one would.
Cheers,
TJ

If you want a nice looking set of smoothies check out Sean Roe's
kit at www.roeracing.com blk or red. I replaced all my factory tubes with his smoothies and also my rad hoses (5), looks nice under the hood.

My '01 idles at (what looks like) 550 RPM. Been that way from the factory and has not changed for 7,000 miles. Tough to compare with accuracy since I think the tachs are not that precise, but my understanding is that 500-600 is normal (at least on Gen2's).

Why would you think it is too low and that the dealer is lying to you?

My '00 idols at 600.

First off I didn't say he was lying!
Second of all they have almost zero experience with Vipers.
They've never sold a Viper and have only serviced mine.
So how would he know it's normal? Maybe he knows, maybe he doesn't is all I thought.
I appears as though he knew. Good for him ......"applause".
Most cars that I own and owned 03 Honda Pilot, 02 AMG 32 Mercedes, 02 SL 500, 99 AMG M55 SUV, 02 Chev 4x4 ext cab,
sold- 99,98,97 Dakota 4x4 ext cab, 84, 80 vettes etc...
They all seem to run around 800 RPM.
Thats why I asked the question Micheal.
Have a good day ey!

The 1st mark on your tach is not ZERO!

The normal idle 'appears' to be 600-ish but more like 750. Your dealer can hook up a DRB and see the digital RPM readout.

ACR hoses indeed fit non-ACRS, but they are bogus-expensive.

Several vendors here offer hoses from $49 (rubber) to $125 to ACR $240. YIKES

Be sure to get 5-layer induction hose, meant to hold up under vacuum/suction. Not 5-layer turbo hose, intended for pressurized use. We have seen turbo-hose begin to distort on a dyno at 4500 RPM plus. Too much sucking going on, esp w/ OE filters.

I think that after I installed the VEC1 my car is runing at 500RPM

Thanks JonB,
Your response is very logical!

I thought the same thing with my 97. Went to the dealer, they hooked up the DRB...I was around 740. Like everyone else says....it's just tach error.

OBDII-Software (EASE) shows an idle rpm of 700-720 for my GTS.
