DON'T PULL THE RACK LIMITER-turn up the pump instead.

no need to remove the rack limiter. No gain over just maxing it out. Max it out if you do not know how to properly tune the ip, but leave it in there in case someone else tunes it properly later. If the governor is not set to go to max fuel then the rack will never reach full travel anyway. You will be surprised at the differance between a nicely tuned pump and just one that had the limiter removed in terms of better drivability.

You gain a few extra mm in rack travel with it out. More than likely you pump needs some new springs for the counter weights and you simply overcame that by removing the limiter.

Turning the elements gave me the most power out of all the mods. Rough running but more power.

Hey Simpler!

Thanks for the link to Cheap Tricks. A lot of these are happening automatically on mine as it moves to the S10 (no exhaust system, for example) and I'll have to think about removing the ALDA and other changes.

Do you know if there's an Ebay (read "CHINESE") turbo that's an appropriate upgrade? Mine needs a rebuild and it might be cheaper to go with a cheapie replacement. What size would I look for (other than a T3 base).

Also - any opinion on putting an intercooler in an ice chest and plumbing the turbo thru it? At the track it's no big deal to add ice before each run.

Thanks
Dan

Taking the rack limiter will not net 40hp. Adjusting torque control and max speed settings in your pump governor just might. After that, a small rack adjustment will be all you need to make your 617 perform as best as it will. As stated earlier, you can find a detailed write up on RW governor settings at the STD forum.

As opposed to cutting DVs or turning elements, these mods will leave your car idling right and not smoking like a chimney.

Sent you a PM, and yes-an ice box for drag runs could help you out.

The max speed governor starts to act on rack travel quite a bit earlier than 4000rpm, for you're information. Removing the rack limiter will not change that.

I have edited this to help clean up this thread.

Regardless of who you may, or may not be, recommending that someone remove components that provide a practical purpose in a Properly Tuned Governor is reckless and irresponsible.

No one drives their car with their foot on the floor all the time, true drivable performance comes from the Torque Control, which when properly adjusted for performance, will require very little Rack Limiter adjustment to reach EGT limit.

A properly "performance" tuned governor will need the rack limiter to get the most "drivable" performance out of it.

There is a very informative doc that I wrote that explains how the RW governor works, many have used it with great success, more so than the other instructions that have been posted that recommend to remove the Rack Limiter.

Don't leave that there - I'll take it to bits!

See if this works;

Hay 616 -
Want to meet me at the track next Spring and help me set up my pump? I sorta follow the write-up (nothing wrong with the write-up, just the reader) and an experienced hand sure would be appreciated!

The pumps I know anything about were electronics and we sent the computers off the Bosch, who tweaked them to accommodate what we were doing. They didn't want our pinkies in there and wouldn't supply us with the software to mess with them. So what I know about this stuff is "send it over to Bosch" (made many a run to Farmington Hills).

Thanks for the link.

Dan

Farmington is in my back yard so to speak. Where are you coming from?

Even the Bosch training films do not provide enough info to really understand what is going on, only enough info to be able to set it up how they want it. I think that is why some want to argue, as they are basing their statements on the Bosch film strips that have been posted. It is hard to believe, but they really are very crude when it comes to what is going on.

I am sure we can set something up.

Thank you very much - I'm a printin' it out.

I'm retired from the EPA lab in Ann Arbor but have moved to Wilmington NC about 8 years ago - to quote Stevie Ray, "Couldn't stand the weather".

Our track is in Wilmington, Ohio (lots of Wilmingtons, I know). SW of Columbus. First meet next year is the last weekend of April (maybe the 25th. or so - I don't have a calendar for next year). I usually book a double room so I can put you up if you can make the trip. I don't smoke or drink but I DO fart! It's a LOT of fun. Try .

I am sure we can make it happen, you will have to remind me as I will forget, lol.

Keep in touch.
