Sprintex Supercharger

[guzzla]

These supercharger kits are quite popular here in OZ. Especially since Safari stopped supplying the turbo kit and most shy away from a turbo DIY.

I've never been in one but they are said to go quite nicely. From all the dyno graphs and reports I've seen and read, they make really nice torque improvements down low.

Regardless of the new found power, I really wouldn't like to be running boost through these engines without taking the proper precautions like rebuilding the engine to handle the power 'reliably'. Sure, the engine might be able to handle 5psi all day but if you've invested that much money into it, surely you'd want to be getting maximum benefit out of it.

The comment from the folks at 034 was that if we were able to keep the system from loosing control (ie dumping fuel), that we would get more HP out of the motor at higher RPM. The only way to really do this would be with a piggyback IMHO, and in Kalifornia, that would pretty much mean failing the visual bi-annual inspection.

If that's all you need, why don't TRD S/C guys run an Apexi S-AFC (or other similar simple piggyback air fuel controller)? Tune it with a wideband on the dyno, and there ya go...no more running crazy rich up top.

I have actually been talking with the Sprintex distributor here in CO for the last few months and he is scheduled to install their kit on my OBD1 '94 here in the next couple of weeks.

His plan is to use a AEM piggyback controller and an extra injector to manage the OBD1 fuel issues.

Being up at altitude mitigates the factory fuel delivery issues somehwat, but he is confident that he can provide a system with good AFRs, even with the OBD1.

I kind of stumbled into this, but most of the Sprintex blowers coming here go on Jeeps, which are 99% of his business, but he has been looking to import the Sprintex kit for LCs and is cutting me a huge deal on the kit and installing/tuning for free to test it out. It was good timing for me since I was on the fence about keeping the 80 and tearing it down and cleaning it up, but this pushed me over the edge. He's going to install it on my 220k engine while I rebuild another 1FZFE that I have. After the install and tuning is confirmed on the old and tired engine, I'll pop the new one in and we'll re-tune if needed for the new injectors and whatnot.

We'll start with 5PSI, which is really 2.5PSI over sea level pressure and see what happens. They claim that the screw type compressor in the Sprintex runs about 80deg cooler than the Eaton, for whatever that's worth. I am anxious to see if that's true. I also get to keep the stock fan supposedly, another plus.

I figure if it doesn't work on the OBD1, I'll pass it on to a OBD2 owner who can enjoy it, but it'll be cool to see what these guys can come up with.

I am really curious to see how this goes. I would love to get that on my '94. Do you plan on doing a new thread?

 

[davework]

I'll start a thread eventually

davework, what about OBD-II applications (I have a '97)?

Plus, I don't understand the need for an additional injector? The previous dyno graphs shows the truck runs *rich* up top, not lean, which is why it's losing tons of potential power. Based on that, a fuel controller should suffice.

Also, mind sharing the info on the Sprintex distributor in CO? I'm probably gonna be on a few hours away in the next couple of months, and would be very interested in discussing a possible OBD-II install...

 

[landtank]

the OBDI trucks use a vane style air flow meter and don't respond the same as the OBDII trucks. Once the air flow meter reaches it's max the truck leans out real fast. The 7th injector would kick in at that point.

I would think OBDII applications would be easier, especially with mild boost, basically similar to TRD.

His claims that he can get it to work on OBDI is what sold me since I was basically under the impression that forced induction was out for my truck. For a OBDII truck, I would be more tempted to go for the TRD since it is a factory smog compliant plug and play option.

If everything works correctly, I was thinking of perhaps trying for a group buy which would get everyone some savings on bringing them over from AUS.

 

[aboisvert]

I'm interested in group buy, and I emailed them for price shipped to NH.

That's a lot more money for than TRD, even without the intercooler.

Here's their response:
-----------------------------------------------------------------------------------------------------------

I'm considering your supercharger for my Land Cruiser, 1997 , OBD-II 1997 FZJ80.

I have a couple questions.

1)What gains are there to the intercooled setups? In performance and/or reliability. What is value for the added money?

The main advantage is reliability. Cooler inlet air allows more timing advance giving more power and response without the risk of detonation.

2)How much for each of the systems shipped to the USA, zip code 03809.

We recommend the Xede ECU upgrade with 2bar map sensor especially on 80 series vehicles for its superior tenability. Non intercooled $$5800 AUD shipped and $7800 intercooled.

3)Is there a 'lifespan' for these systems before they need a rebuild? If so, what is it?

At 40,000 miles oil change in supercharger, at 80000 replace snout bearings and seal at 160000 full rebuild or replace the supercharger.

If you have questions, please let me know.

Thanks,

Just an update for anyone who is interested.

This has died on my end. The guy at Boostec promised and promised results, but could never deliver anything. At this point, I am just hoping to get my money back. I wouldn't recommend dealing with Boostec.

I am going to look into Bullet and see what the possibilities are there. I'll update if I hear anymore.

 

[FDNewbie]

Dave, do you still have your Sprintex setup? Are you looking to part with it? Cuz it should be a lot more of a straightforward install on a 97

 

[davework]

I've been emailing back and forth with Bullet.

http://www.bulletcars.com/superchar...nder-1fzfe-80 series-supercharger-system.html

Here's what I found out:

1) The kit they provide needs the XEDE computer, which comes with a new MAP sensor with ports for the two injectors they provide. So the XEDE takes over management of all the injectors. The two injectors that come in the "basic" kit are pointless without the XEDE, so if you get the $3995 kit, you need some type of piggyback to use the injectors.

2) The kit without the injectors can be purchased for $3885. I don't want to replace my OEM sensors, so I'd likely go this route and then get a piggyback to manage a 6th injector.

3) There is no PAIR Valve relocation, so you have to lose it, or do it yourself for OBD1

4) Freight to CO is $650...ouch! This is a deal killer for me. At $3885, I am right on the fence, but at $4500 I can't do it.

5) 15% discount for an order of 5. That's $3300 for the no-injector kit. Not sure what this would do to the freight cost. If anyone is interested, let me know and I'll find out.

Never got it.

 

[FDNewbie]

Thanks for that info. I emailed 'em.

If anyone's seriously considering this, and wants to save on shipping costs, lemme know. I got a bunch of stuff comin from JDM-land by container, and can bring over the parts that way. Shipping from Australia to Japan is pretty cheap. Prob cut total shipping cost in half.

 

[Korasher]

I found this thread searching for my info on the Sprintex vs TRD for a future purchase. No one seemed to have mentioned the place i discovered the Sprintex and its a US distrbuter which might help with shipping on the pricing end. The only problem is they don't offer the intercooler option that Bullet does. Just thought I'd share. Thanks for the info so far guys, and I'm sorry to davework with that bad shop.

[davework]

Good find. He is on Mud as Socal FZJ80. I'll see what he can do.

Sorry for the dumb question but what makes the this supercharger better than the TRD supercharger? Is it higher efficiency? Requires lower hp to spin it?

How about the rotrex supercharger? How Superchargers Work - Rotrex Superchargers Sounds like it has "turbo" like efficiency while being a supercharger.

 

[FDNewbie]

Korasher, nice find!

Hey Dave, what email address have you been using to email Bullet? I've emailed 'em twice at supercharge@bulletcars.com without an answer. It may just be my AOL email address that's hitting their spam/junk mailbox.

That Rotex looks like a hydrostatically driven turbine. Maybe it's a smaller unit that runs at much higher rpm?
