Sprintex Supercharger

[Bugbee]

Hello...

After a search I don't think these questions have been asked before:

Has anyone installed a Sprintex Supercharger in a FZJ80?
How was the quality?
How easy was the install?
How impressive was the power increase?
How many miles on the rig when you installed?
Any reliability issues on supercharger or motor afterwards.
Did the transmission hold up?
Any suggestions?
Comparisons to the TRD unit?
Would you do it again?

Thanks,

P.S. The last Toyota I owned was a 1982 FJ80 and the motor sucked for power and gas mileage so I'm checking upgrades before I pursue buying a mid 90s FZJ80.

Never heard of a Sprintex supercharger but the TRD works well.

1982 FJ80?!?!?!

no first hand experience but i have a review in a 4wd mag. the posted 90kw at the wheels or 120hp. and 249Nm of torque or 183 foot pound in your language. which according to them is a 45% and 48% increase respectively.

according to the article none of the drive train was changed to cope with the extra power. in terms of reliability i understand superchargers require a higher level of maintenance than what would normally be required.

sprintex is an australian company and i understand parts are made locally so quality should be good.

hope this helps a bit.

Sprintex latest kit is great there kits are high quality and very well engineered ,they have there supercharged 80series and 105 series , oviously hard for you guys but if you go to there shop they will take you for a ride and then let you drive to see if you like etc , if I didn't go the turbo route I would go sprintexs blower kit for sure.there STD kits run at 5 psi for reliability but you can always change to suit your needs.

Looks like a nice kit.

Back from the dead...

So I recently looked into the Sprintex supercharger kits for the 80: Sprintex - Superchargers and Supercharger Systems | Supercharger Systems. Their claim:

50% power increase at wheels:
- Factory: 96 kW (129rwhp) @ 4550 rpm
- Supercharged: 145 kW (194rwhp) @ 4550 rpm

After searching through a ton of threads on the forum, here are the TRD supercharger numbers for comparison:

One dyno result: https://forum.ih8mud.com/80-series-...supercharger-dyno-tests-data.html#post3619813

25% power increase at the wheels:
- Factory: 100rwhp @ 3800 rpm
- Supercharged: 125rwhp @ 3800rpm

From a Slee supercharged truck (https://forum.ih8mud.com/80-series-...upercharger-dyno-tests-data.html#post3620290)

21% power increase at the wheels:
- Factory: 138rwhp
- Supercharged: 167rwhp

So it looks to me that the Sprintex supercharger kit yields DOUBLE the power of a TRD supercharger (if their numbers hold true). That raise anyone else's eyebrow?

More importantly, anyone have any first-hand experience with their S/Cs?

How much???

So I heard back from Sprintex (I was asking about price, availability, and compatibility with an intercooler). They said the following:

"Bullet Cars have taken over our Landcruiser kits. Bullet Cars - Supercharger Kits, Performance Parts, Bullet Roadster Cars

They will be able to quote pricing and shipping and they also offer a water to air intercooler option."

If you check out Bulletcars' website (Bullet Cars - Supercharger Kits Toyota Landcruiser 80 Series), it makes sense now. They DO make 45% more power, but that's utilizing a "pre-programmed piggyback ECU, which alters the fuel and timing requirements to suit the Supercharger system." No other upgrades necessary.

Price:
- $4490 AUD ($4660 USD) – Non Intercooled Supercharger system
- $6990 AUD ($7250 USD) – Water to Air Intercooled Supercharger system

A bit pricey, but it's a heck of a lot more power, and according to THEM, install is pretty straightforward:
- $1000 AUD ($1040 USD) – Non Intercooled Supercharger system
- $1500 AUD ($1550 USD) – Intercooled Supercharger system

I got quoted $4K - $5K in parts & labor for a TRD S/C install by 80 shops... (S/C NOT included in that price). Ie, IC + parts & install around $8K when all was said & done. So it seems that the Sprintex unit is not only comparable, but yields much more power, and doable WITH an IC setup for about the going price of a TRD S/C install, start to finish.

For $4-$5k are they doing a top end rebuild (new head, hg, thermostat, water pump etc etc)? That price seems extremely high if you are simply bolting the supercharger up. For what it's worth, I spent a lot less with a reputable shop on my SC install and had the top end rebuilt.

Yes, you're correct. It's for doing all the maintenance items you should while you're in there. Mind sharing how much it cost you for install + top end rebuild?

 

[CycloSteve]

My TRD setup is running around 185 HP at the wheels, as registered on an AWD dyno. Each dyno is different.

I would be interested in seeing their WAIC system for sure, as a few folks are working on TMIC and WAIC systems here (atoyot1031 and LandTank). Intercooling would allow you to safely push much more than 5psi, up to perhaps 10psi without changing engine internals.

Here is my dyno run from a couple of years ago; TRD with 2.5" mandrel bent high-flow exhaust.

Why are there two sets of prices

 

[FDNewbie]

One is parts, the other is labor

Steve, you ever dyno it before the exhaust? Those are the highest rwhp numbers I've ever seen from a TRD S/C. Also, where do you live if you don't mind? Curious about air temp, humidity, altitude, etc

I stand corrected, I spent just south of 4k for the top end rebuild but the install was only $340 in labor. I had to dig up the invoice to jar my memory. My bad.... carry on.

 

[FastCarGuy]

I have been watching and searching for more power. A Toyota dealer quoted me just under $5K for a TRD SC ($3400+ $1500 labor) and Slee quoted just under $10Kfor a turbo installed with intercooler etc. I believe the Turbo would ultimately put out more power, and by the time you import from down under you would be getting pretty close in cost to the Slee turbo

NorCal. The Dyno was done at 034Motorsports. Temps in the low 70's, pretty much sea level, normal humidity.

The dark lines are post-exhaust, the light ones pre-exhaust. Red = HP, Blue = TQ, Black = Wideband AFR, and Green = boost pressure. Did two different runs over several weeks.

Steve,

So you were at about 165 - 170 rwhp prior to the exhaust it looks like, and up to 185 rwhp with exhaust. That matches Slee's numbers.

 

[Wheelingnoob]

Another scary lean S/C dyno graph, I'm amazed these engine are strong enough to take it to be honest. Looking at the power and TQ you can see as it starts to richen up (I'm using this term loosely) the lines kick up at the exact same place. That shows that the engine is running lean and losing power. That set-up with the correct fuelling would make over 200whp if there was a way to do it.

I am not sure if you are reading the graph properly. The black line (which is AFR) shows that at 4200 RPM the ECM basically starts dumping fuel and then the HP and TQ flatten out, then drop off significantly (with the AFR settling around 10 at 5000 RPM). At most other times the system is pretty steady at 13.33 AFR, which in this case was read at the tailpipe, not pre-cat, which would be much more accurate.

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.

...back on topic, does anyone have a picture of the Sprintex intercooler setup?
