- expensive to buy (>$3000)
- must use premium gasolone (90+ octane)
- somewhat reduced gas milage at normal throttle
- greatly reduced milage at wide open throttle.
So, if you drive "normally", keeping the motor under 2200 RPM, accelerating gradually, etc... your milage won't drop too much maybe 1 or 2 MPG. Using maximum throttle at lot will use a lot more gas. More wear and tear? Probably not if you don't abuse the extra power. I'm not sure how much strain the stock Tundra drivetrain can handle, but if you "over do it" often, things wear out quicker.
I called trd 3 weeks ago and they said an increase of 100 hp and they will be providing a chip to take care of the fuel timing issues.My biggest concern would be the diffs and the tranny, I have no doubt the engine could handle it.If you drive normally you probably won't be using the s/c at all cause it only kicks in when the throttle is applied.My sis and her husband have a gtp grand prix s/c and it flys when the s/c kicks in.
In the case of the TRD blower, it runs all the time. By this I mean, it is constantly spinning (driven by a belt). This creates an extra load on the motor, thus decreasing milage. On the plus side, the blower uses less HP than it helps create! As I posted a long while ago, the TRD blower is made by Magnuson for TRD. Some of the Magnuson blowers have bypass valves, which vent the blower housing to help prevent the above loss at low RPM. I'm not sure if the TRD one will have this bypass valve.
Put another way, the supercharger is running all the time, it does not get turned "off" and "on". At low RPM (part throttle), it's not doing a lot of work, but at high RPM it's pumping a lot of air (thus enabling you to burn LOTS more fuel) and that equals power.
I GUESS (hope) IT'S a MP112 OR a MP90 4TH GENERATION WITH THE Internal Bypass Valve.
(bypass valve virtually eliminates parasitic power loss during part throttle operations)
Is a new air intake kit included or are all the airbox mods now considered mandatory after the install?
A bigger blower isn't always better, i read this in a s/c t/c book I have. I will have to look up what it said but I clearly remember it stating that bigger blowers don't necessarily mean more power.I'll look it up and get back to you.I think the v6 is the m62 which is the most common.Later.
This is just general information. A supercharger or Turbocharger will work the same (or very close) in the higher alt. regions.
Assuming it's controled by some sort of wastegate it should still generate 4psi of boost. It will have to work a little harder to do this since the air's thinner, but 4psi of boost is pretty low. I can't imagine there being a noticable drop in HP
Again, this is just general information about how a supercharger/turbocharger works. I have no idea exactly how the TRD supercharger/ECU regulates boost or controls fuel etc..

Release date is set as MAY 27th.......will this change?? I give it 2 weeks after that date just to make sure...

This shouldnt be that much of a suprise to all of you......Steve did say that it may be a few more weeks. (look above).

I'd rather spend the time waiting for it to be done right then be in such a hurry that something gets broken in my Tundra. Time is on our side here....let TRD do their thing and get it right the first time for all of us.
Originally posted by oz Well it seems that all of us that have been waiting for the "SC " that are prays have been answered. Look for the SC to be released by late July.
hey all,
I have emailed this post to SteveG for confirmation. When i get word or if SteveG writes in, we can get the scoop directly from TRD.
They (TRD) are working on the part# and price for the SC. The reason the SC has been pushed back so much is that TRD only has one dyno machine and were having a glitch w/the piggyback computer. The piggyback computer is actually and "EBC" Electronic Boost Control. They SC had been done for some time now TRD had 4 prototypes and the EPA had all 4. The upper mangement have SC on there personal Trucks, one is on a Tundra and the other is on a Sequoia. Good things come to those who wait. So I would look for a relase date in late June but most likely mid-July. As for me I have my parts manager put one on order for me
more waiting
