2010-2014 Magnuson Supercharger FJC kit

Im finally here posting about the new pre-production S/C. We have had it and its been installed on my shop truck 2014 TTUE Fjc. Excuse the delay but we have been more active about this development on our Instagram account @siick_motorsports and on fjcforums.com (owned by the same company as this forum) since we are a vendor there.

(mods if this is not allowed let me know)

Ok so i know many people had isssues with the previous 07-09 taco/fjc s/c tunes. And seems magnuson was more catious this time around. Hence it wasnt just released for sale. It was on their 4runner for a bit over a year with the tune. 10 final pre production kits were released before it out to the general public, for more testing.

The kit utilizes the same intercooler as the 07-09 s/c behind the grill. But the intercooler inside the s/c housing is off of the 5.7l Tundra s/c kit. It's a 1.3 liter size blower.

It will be CARB legal and will include the tuner already unlike the previous kit which was an extra.****CALIFORNIA customers will have to wait till March 2018 for them to be on sale. Magnuson is just waiting for the get the carb no. & certificates.
***Out of State you will be able to get them end of December.

Its gunna be doing 6 lbs of boost. Torque & horsepower curves are remained very consistent and smooth after each pull in the dyno. Two different dynos were used (dynojet, dyno dynamics) for a total of 8 pulls.

Our fj is a 2014 TTUE automatic, w/ stock gearing & 30,000 miles . Tire size 285-75R16. It only has 2 out of the 4 catalytic converters (dough thorley y-pipes & jba cat back).

You can have a Snorkel on this kit without having issues. OEM air intake is re-used, if you have the TRD air intake that will also work.

The kit is vert straight forward and if you have the tools it can be installed in your garage. Spark plugs will have be gapped per instructions. So make sure u have an gapping tool for iridium plugs

Driving the fj is much better now. The transmission is not hunting for gears anymore. Rpms wont shoot up sky high on downshifts due to the added power when going up grades. The rpms are more constant when driving. Its not obnoxiously loud. In normal driving you forget you have ther supercharger, and when you do step on it is midly loud. Mpg, (i know most dont care) for the guys that do care, we have seen an increase around 2.5 miles more driving at 75mph on the freeway (southern California). Possibly more if were driving at 60-65 but we dont.

We have driving the truck on dunes, city, freeway, dirt. Different locations/ terrain. And we are very satisfied with the performance. Passing lanes or getting on the on ramp with our RTT and gear is not an issue anymore. The power is there when you needed. On the dunes it helped a lot specially going up the long steeper dunes.

For the guys with Crawl Control. The system works just as it would without the supercharger. The added power doesnt conflict with the system at all. Some guys had been asking about that.



For anyone local to southern california the truck is currently at the L.A Auto Show on display and can go check out the supercharger.

Install notes** certain custom modifications were made to accommodate our shrockworks bumper / winch to be able to clear hoses , intercooler, and s/c water pump.

Re: 2010-2014 Magnuson Supercharger FJC kit

'07-09 Magnuson Kits were supplied with the Bully Dog tuner....which was problematic for some. What tuner is being included in the 10'-'14 Magnuson kit? Can the '10-'14 accommodate the 2.85 undersize (overdriven pulley)? Does the tuner account for high altitude and is it still able to produce 6 lbs of boost at say 10K altitude?

Sorry to borrow the term, but this looks absolutely siick! So clean!

In regard to the SC cooler in front to the radiator, I wonder if it affects engine cooling by blocking the radiator significantly? Perhaps differs depending if FJ is going slow off road(i.e., in sand) vs down the Freeway at 70mph. Have you watched coolant temps in your different driving environments?

I have an aftermarket tranny cooler mounted in the same place as the SC cooler, and can see that this would be a problem to mount from the get go.

Q: "In regard to the SC cooler in front to the radiator, I wonder if it affects engine cooling by blocking the radiator significantly?"

A: I have had a Magnussen (TRD) S/C on my '08 now for a few years and never saw any impact to engine cooling.

Re: 2010-2014 Magnuson Supercharger FJC kit

Question for Super Slick: has anyone yet provided a side by side comparison of the '07~'09 and the new '10~'14 performance (dyno graphs)?

Since both SC are running at 6psi I am thinking that it would be a pretty fair comparison of the two, "out of the box".
I am curious as the later engine has a couple more hp / fewer ft-lb if that condition remains or if through lessons learned and additional development time (or thanks to roller rockers and twin VVTi) they were able to get more.


edit: oh, wait, I was able to get the '07-'09 graph from Magnussen's web site just now:

Boosted '07-09 280hp/291ft-lbs
stock '07-'09 got 239hp/278ft-lbs
(+41hp, +13)

Boosted '10-'14 286hp/280ft-lbs
stock '10-'14 got 260hp/270ft-lbs
(+26hp, +10)

If the addition of a Magnuson SC is only an increase of net 26 hp then this is not a worthwhile upgrade. Seems like something must be amiss with these numbers.

Btw- thanks for the coolant data/info prev post!

Are the magnusson HP/Torque numbers at the wheels? If so, comparing them to the stock numbers (which I believe are at the crank) isn't a particularly even comparison, you'd have to put a stock 2010+ on the same dyno as your SC one to get a real power comparison.

I could be wrong, but the numbers that Toyota puts out for hp ratings are likely numbers that the engine puts out without mentioning the loss of power from the driveline. What’s posted above is “to the wheels” numbers.
