At the Performance Racing Industry show in Indianpolis last weekend I had the pleasure of being introduced to this company and the two great individuals running the booth.

TURNONE produces all the powersteering pumps for the ASA stock cars which run the LS1 engines. If you need a pump they can and will help you out with either a rebuild of yours or supply a new pump. They will free up some horsepower as well as make your pump more reliable by reducing the fluid temperatures. They also have a really cool aluminum pulley to replace the plastic one.

Thanks!

Mitchntx and several others (shortbus? and a few more) are running them, all seem to like them so far.

That pulley is a nice piece as well.

Mine is freaking AWESOME!

I think Keith turned me onto them when we were all happy at LS1.com

When was that?

Before or after the coil over discussion.

I had one modified by them and am quite pleased with it.

Will this part obviate the need for a separate ps cooler?

It should certainly help as the main temperature increase in the fluid is likely because of the constant recirculation the fluid is doing. The pump produces way more pressure than is needed at higher rpm where you spend most of your time racing.

I have one in my car and loved it this year. Didn't have time to thermocouple the fluid temps though. I'd have liked to understand if a cooler still did much good when using the lower flow pump.

I had one on my old LS1 and it worked great. The buyer of the car open laps and autocrosses it and hasn't had any problems either.

I never got to try the TurnOne pump without my small cooler, but I can say that:

TurnOne PS Pump + Small Permacool Cooler = NO PROBLEMS!

I can say that just a LG underdrive pulley, small permacool cooler and Valvoline fluid meant no problems too. At almost 100,000 miles I was still on my original p/s pump. I went for the overkill this year and got the Turn One too.

Do you buy these direct from Turn One? What's the cost?

I don't remember the cost and I gave the receipt to the buyer of my car. Just call them and find out... A search here or at the LS1.com AX/RR forum will find their phone number.

I think/not sure it was around $140?

I seem to recall $180 and $40 for the pulley ...

Buy direct from Turn One or Lingenfelter markets them as well ...

That reminds me - unless you like fooling around with pulleys, order one with the pulley already on it. It will halve the installation time.

IMO, the pulley isn't worth it if you have the tool or access to the tool. It only takes a couple of minutes. The aluminum isn't saving you weight or anything over plastic. It is more durable, but this isn't a high stress or easily damaged part. $40 is $40!

Are the LT1 and LS1 different? Where can you buy these besides directly from Turn-One? Their web site does not have costing. What are the costs?

Call turn one and ask. Any other place like Lingenfelter will have a markup.

The reason for the pulley was that ASA cars were breaking the plastic pulley. For most people it doesn't matter. For the "real" racers it certainly is helpful. I can leave the whole powersteering system in tact when working on the engine. It's nice to have access to the bolts with out having to remove the stock pulley.

It also saves me the time to go find the puller in the toolbox and the time to remove/install the pulley.

The plastic is also such a nice looking piece.

We have also warped our plastic pulley, can you get a replacement pulley for $40, a pulley of know history...not junk?

ERV

I knew it was for the ASA guys, but they run at 6000+ rpm all the time, not our 3000-6500rpm. I guess having access to bolts is a good idea. I don't care about the looks and I haven't warped mine yet it in ~20 track days.

You make some good points though!!

It took about 2500 race miles and two pumps before the warp. We run the ASA motor and try to keep the rpms above 4200rpm.

Like you said, I wouldn't expect anyone to have these problems.

ERV

Can anyone confirm if these are ESP legal? I need a new pump due to bearing failure, and I only got 40K on the car. Seems to me if I can find one that will last longer and run cooler that would be a total bonus to durability, but not much gain in performance.

The last time I checked, they are not ESP legal. (That's why Pimpmaro is in SM/SM2).

Yup, they are not ESP legal. I love my Turn One pump however. And you can also get it in standard fittings or -6 AN fittings if need be.

Damn, that means I'll have to go thru all that work of replacing my pump just to put on another POS stock pump. Oh well, thanks guys.

Just take the TO sticker off and use the stock pully and it will look like the factory piece. No-one will ever know and there is no real performance advantage.(~2hp)

Hummm....

Another thing to consider:

$295 for an OEM replacement from local dealer
$225 from Turn 1.

I wonder what I should do.

Well, I just installed a Turn One, and left the sticker on as a weanie detector. Since underdrive pulleys are legal, and will probably free up just as much power, only an idiot would protest

It was worth it to get the preinstalled pulley just to be able to use the "pimpmaro" method of pulley removal. There isn't much room to work in front of the pump, so using a flat steel wonderbar to shatter the stock pulley saved a LOT of time. It only took about two seconds (mostly to just position the bar) and one tug. I was surprised by how brittle the pulley turned out to be.

The bolt access (should I ever need it) is just a bonus.

By the way, there's a great write up on pimpmaro's page. However, he has the AN version, so one crucial detail is missing. You will need a 16mm flare nut wrench. I only had 15 and 17 and didn't have time to run out to buy a wrench. I had to cut open one of my good closed-end wrenches because I didn't think far enough ahead

That's actually the trackbird method. I'm the guy that fixes everything with a large collection of hammers and force multipliers. (the un-subltle one of the two of us).

:leaving:

I, too, subscribe to that way of thinking.

I got a good laugh out of the new machinist at work when I asked him for the fine adjustment tool:

Wow, I really am home.....

That's what my grandfather used to call a precision carburator adjustment tool.

"A 12 lb, high precision tweeker, with a 36" handle".

Hey now, you simply supplied the pry bar, I supplied the "Hell I'll just snap it... I just don't care at this point" attitude. Well, ok, so you also supplied the training in the arts of the kung fu hammer.

I'm really sorry about the missing detail regarding the flare wrench. I kinda threw that together on the quick and I've been screwing around with the new site for awhile now... I've just been too swamped between work and school to get anywhere on it. Maybe over Christmas break?

No apology needed. I blasted ahead, secure in the knowledge that I had a set of metric flare nut wrenches. Yep, had both 15 and 17, just no 16. I should have checked BEFORE I made the run to the store for other stuff.

I was actually unable to find a way to use the hammer. My big crowbar wouldn't fit past the tank, so I switched to my flat nail pulling bar ("wonder" or "gorilla" I think") and the light test pull was enough to shatter the pulley.

I have an assortment of those at home that have been made, usually at 3am, while working on something that needs done tonight.

Trackbird's large craftsman pry bar worked perfectly. I used the small "casting nub" just above the shaft right between the pump and the pulley. A good tug and the pulley blew apart.

Kevin is a great teacher when it comes to destruction.

The "Six Million Dollar Man" started out with "We can rebuild him (it?)".....

Well, I can smash it or otherwise destroy it.....

Yin/Yang, all is right with the natural forces of the world.
