2009 HP with TRD supercharger and TRD exhaust

tbohen [OP] · 07-01-2009, 08:42 PM

I thought this would be easier to find, but maybe I'm not using the right terms.

Picking up my 2009 with supercharger and exhaust next week, putting on an AFE CAI as soon as it gets home.

Any idea what rough HP I will have?

Thanks feel free to point me to the proper thread!

super charger specs on stock 4.0L are 304HP and 334ft/lbs.
My guesstimate as to what the crank HP number would be with an intake and exhaust, ~320HP and 350ft/lbs
This is a guess based on what those two items do individually to the stock motor.

Really? hmmm... That sounds like a lot. I was gonna say less, but then after thinking about it, it may be possible. If this were the price is right, i'd say 317 HP and 344ft/lbs.

Thanks, my pulled out of my butt guestimate was an additional 100HP, so I wasnt way off I guess.

That is a by no means a way of coming up with your HP/TQ numbers. You mention that you are adding a CAI... good Idea. You also need to add a goo catback exhaust, and some Headers, IMO. Then you need to get a Unichip or APR-X1 so the SC can be custom tuned, and then you might see some good gains.

I don't think you can get any kind of accurate measurement by just adding up all the individual HP and TQ claims on each of the performance mods you've made. Get it how you want it and then get it on a dyno.... and prepare to cry when you see how little of that power at the crank makes it to the wheels.

I think URD is releasing a new supercharger for the Fj. Those can produce far more power than the TRD's "mild tune". I'd shop long and hard and make sure you are fully educated on the benefits and drawbacks of the TRD, or any Supercharger. You may just want to sit tight for a bit and see what becomes available.

Well said Toledo.......tbohen try to get behind the wheel of one with Supercharger vs say gear change & exhaust. The later will be cheeper and I bet you will feel it in the seat of your pants better. Haveing said that good on you for getting a supercharger. Really I'm jealous as us Canadians can not get the TRD yet and the URD voids our warrenty.

I'm not antisupercharger, unless that annoying whine I've heard on YouTube clips doesn't go away. I could not even begin to tolerate that sound. Even when he let off the gas it was still whining like crazy.... and I mean loud. My truck in super loud to begin with as is.

I may even add the TRD supercharger after I get out to Montana....in like FOUR DAYS!!!!!!!!!!!!!!!!! I need to see if the supercharger will help due to to the thinner air at elevation at my new house. Plus, if it is quiet, I just want one.

Is the URD going to make that annoying sound? I don't care about warranty. I've beaten my rid so good, they laugh if I ask about warranty coverage. If the URD isn't loud, maybe someday I'll get one.

But a regear may be an option too!

Well I'm not that worried about EXACT HP I just wanted a rough idea.

And I'm going with the TRD so I have warranty from Toyota.

One of the nice things about the TRD is that it is very quiet and doesn't have that turbine whine that some others do. Without knowing it was on there, nobody realizes I have the TRD SC until I open the hood.

Regear wasn't really an option for me, since I take a lot of road trips in my FJ and the extra RPMs would kill my hwy cruiser status. It's nice to set the cruise control on 85 and have the engine just sort of loaf along with plenty of oompf to spare.
