Engine break-in after Arrow rebuild....Did the guy who wrote this ever drive a Viper

[94 RT/10 Black MAMBA]

He wrote that you do "light throttle run-ups":
to 2,500 RPM first 200 miles
to 3,500 RPM next 200 miles
to 4,000 RPM next 200 miles
to 4,500 RPM next 200 miles
to 5,000 RPM next 200 miles

Does he know how fast you'll be going in just first gear at 5,000 RPM?????

Evidently not..

Break in is a matter of common sense. Don't let it idle for long periods, don't drive at a steady RPM, don't get it hot, don't run the silverstate classic. But, driving for perscribed mileage at certain RPMs is; well if it makes you feel better fine. Remember random engines are taken from the line and put on the dyno, Arrow engines are dyno'ed before they are shipped back? You think the dyno didn't go to red line? Drive em brisk and use common sense and you'll be fine. Drove my 96 briskly and it's the fastest stock motor in the country. 11.05@124.

Hope you have as good luck as I have with your Arrow. Ours had 1421 miles on it when I noticed an anti-freeze odor in the exhaust when it was first started in COLD weather.Called Janni Cone (NC-VCA Pres.) and she directed me to Tom Sessions (Viper tech). After evaluating the engine, I was given choices of repairs. Being a former diesel/auto mechanic and as a hobby building "Late Model Stock" engines for Ronnie Thomas, I choose Arrow without reserve.

Breaking in the engine was very important, but would be hard to as you descibed on the highways. I broke my in on coutry/mountain roads. Your car "engine" does not know mph speed but only reconizes RPMs and LOADs. The steep hills and aboundant curves worked quiet well. Also to my understanding, Arrow runs the engines on a dyno before leaving their facility.

Drove the GTS to VIR 2001, and upon arriving, had 1100 miles on the Arrow. Stayed on the track alot, 384 miles in 3 days. Was very conservative on the brakes as did not want to discolor the white "Viper" on the front calipers. Turned 2:22's with a passenger and used only 1/4 of the factory brake pads. Very conservative on the brakes. The Arrow is a "ton" stronger than the orginal engine, but niether has been dyno. Plan to dyno soon.

By-the-way, Tom switch the engines and the job was SUPER!! No indications anywhere that the engine was changed!

As with anything that is "Man Made", it is suject to trouble, so best wishes.

Paul, are you saying that you DON'T run it up to 5000 rpm on occasions such as entering a LONG, straight freeway ramp?? Must admit that I suredo....though I do not drive around town in 1st gear at a sustained 5000 rpm

It's the fastest stock motor in the country. 11.05@124.

I assume stock motor w/slicks, etc.?

This is a tough one to relate. Motor has never been apart. Yes the car ran that number (11.05)at the Viper Nations with slicks, car has headers and 3.55 gear. I personally have not heard of anyone running faster with an untouched NA engine.
