I just saw this today... www.torqhead.com

Looks like it retains the stock harness with no modification and the reluctor wheel and sensors are outside the timing cover, so only the hub needs to be removed and replaced. Supposed to be coming out this fall, so I will keep any eye on this.

 

I've been following it for a bit now. I love everything about it except two things that haven't been described yet.

The hubs - Is he making four different ones for the four lt1 hubs that are available?

The pcm - if you fry one can you grab another 411 pcm and transfer over the adapter, or is the onfrom them the only option? I don't want to have an awesome system for a few years, watch the company go belly up, then be screwed with nothing to replace it with. The rest of the parts are solid or serviceable with off the shelf parts. I just don't want to see another Delteq support issue.

 

It could be a standard "short" hub with a different spacer behind it for the different versions. As far as the PCM, yes, that is a big concern. Maybe it's standard 411 PCM "guts" with some adapter board inside that's their "proprietary electronics". I signed up to be a beta tester since it is supposed to be discounted. Not sure if I will follow through or not, but 24X is a conversion I expect to make at some point anyway.

 

On their website i didn't see any details about which kind of opti drive they built their kit around. If you have to convert from a spine drive to pin drive that adds some complication. It's nice to see companies still looking at new products for the LT1.

 

In for discussion

 

I just read the entire page in the link, they state they make both pin and spline drive, they also state they make all 4 hub designs used on the LT1 platform. seems the only question would be the PCM availability if the company doesnt make it. however it wouldnt be that hard to repin your harness with a set of 411 connectors and use a standard pcm if the need arises.

 

I wouldn't mind doing that. I only saw "Proprietary and robust electronics were employed on the inside of the OEM 12200411 PCM to accomplish this. None of the sensitive electronics GM designed for reliability are compromised."

I take that as they did a more complicated internal repinning. I would possibly opt to save money and not buy one of their PCM/s and just re-pin my factory harness so I won't have to go back to them if something happens.

 

Interesting, I wait and see.

 

That was my line of thinking also, I have gathered everything for the swap except the EFI connection kit, kinda irritated me when they increased the price when I was about to order so I put the project on hold. if the hub and sensor setup here comes in at a reasonable price I'll definitely give it a try.

 

Is there any concern about dirt collecting on the crank reluctor and messing with the CKP sensor?

If someone was so inclined I bet you could build a halfmoon style shield to keep road grime from getting kicked up and mount it off the oil pan bolts.

I assume the TH setup is less than EFI's 120-00067 kit for $540...if not it will be a struggle to sell it since the EFI setup has been proven out numerous times over. Need to sell it at an attractive price to sway people away from EFI.

Either kit you still need a timing cover,modified (or new) harness, coils, coil bracket, PCM and tune.

 

I like this setup. You can buy the 24x/1x relucterwheels, hub, cover and sensors for $570. then you could repin to suit for a 411 PCM, Find coils and have a failry cheap 24X system. Also makes you think about taking a LS1 reluctor wheel and try to retro fit it behind the hub. May be too big and not enough room

 

Where did you see a $570 price for the TH setup?

 

With this kit you dont need a timing cover all the sensor provisions are in the opti replacement plate. thats what makes it so much sweeter.

 

Does it work with an aftermarket hub like an ati?

Click on which one you want, As far as crap getting in the relucter ring Im sure they are using a hall cell that reads something magnetic, Kind of like an ABS wheel/sensor. If you pull those off Comercial vehicles they are usually caked with greas but still work fine.

 

I think there pricing is a little out of line, for those of us that can scrounge up the parts needed to do it on a budget build, then EFI connection is still the cheaper way to go and it's tried and true. this is a nice alternative, but for this $570 for the mechanical portion only, it's a little steep for the budget minded like myself.

 

Ahh, that's right. So for $570 it only saves me from buying a 96-97 timing cover since my car is a 95.

So the way I see it is can I find a 96-97 timing cover for the difference of the 2 kits to make it worth it? Plus the fact that it is the new kid on the block in terms of reliability that needs to prove itself.

I do like the idea of it being all external with no need to mess with the timing cover and install reluctor wheels.

 

Looks like it's under $1,600 all in. Doesn't seem so bad. What does EFI Connection's kit cost all in?

 

Well for my 95 with EWP, EFI's 120-00118 is $835. That includes a billet cover. I would still need to factor in a PCM ($50-$200)and wiring harness ($100 DIY kit up to $750 plug and play), coils+bracket.

 

Looks pretty good.
