If I buy the spacer used, do I need new hardware or anything like that ?

 

I got the outlaw spacers and I'm happy slight notice in power. Biggest notice I saw/felt is the engine block and throttle body after driving are hot to the touch but you can put your hand on it with out being burned. Outlaw claims it lowers engine temps by 30%

 

They include all necessary extended bolts and nuts. All you need is a ratchet set mm not American. Torch wrench and impact gun(to remove bolts) is helpfull but not needed you can use the button up rule for this install. It's pretty fun and only take and hour. You will remove vacuum lines and remove intake manifold. Seems scary but it's easy, I killed it first shot in 1 hour maybe 2. Good luck.. Lol forget to tell you that's if you buy it new. Don't buy it used. Thats just asking for head aches. You need new nipples bolts and nuts maybe about 20 bolts 4 nipples

 

Reading through this thread I was wondering if anyone installed the throttle body spacer with a short ram and had any trouble with the fitment of everything under the hood? Since you add a few inches to the intake length it looks like.

 

Just checking, does the TL kit come with the two studs for the intake manifold? The reason I ask is I bought a kit for the Honda Pilot had no studs provided, but instead there were two additional long bolts.

I have issues with this omission on Outlaws part, so I aborted my install and plan on shipping back their kit. Fortunately, I had to remove the intakes for a different purpose. I would have been pissed if the Thermoblocks were the only reason for removal.

 

Smart move!

 

^ Probabaly. Unfortunately.

The good news - Yes, Outlaw provides the additional studs. All hardware needed for the install is there and is of good quality. Install really was a cinch. Hardest part was taking off the throttle body which really isn't that bad.

The bad news - Certainly no noticeable power increase simply due to the fact that AIT's (air intake temps) are negligeably affected. See my review here (with other AIT decreasing mods):

outlaw spacer is a like a mini MDX spacer. It does increase power just not enough for you to notice with the butt dyno. Do a few WOT runs and you will notice that it is cool to the touch. But if your stuck in traffic for 2hr don't count on it cooling your IM or TB. Heat Soak always wins.

 

This might be true which is why I've left the TB and IM spacers on. Well, that and I'm lazy and don't want to remove them. Figure they can't hurt.

My review is going strictly off objective data - what the engine is seeing (and adjusting timing for) which are air intake temps. They simply haven't changed with the addition of these spacers which is supposed to be the whole purpose unless I'm mistaken. But other forces could be at work here which might make a subtle difference such as intake capacity, actual temps of components vs. air intake temps, etc.

 

I saw your thread. It is very nice but are any of the temps measure during WOT? It seem like the data consist of DD instead of hard driving.

 

^ That's a good point. I don't monitor continuously. I glace up at the gauges occasionally to see where things are sitting. I rarely look during WOT since whenever I'm gunning it I'm usually paying close attention to the road

But you're right: AIT's can drop considerably whenever a larger volume of air is running through the throttle body like at WOT (this is assuming WOT results in high RPM's however. WOT in 6th gear at 50mph isn't going to do much as far as air flow is concerned since the engine simply isn't moving very quickly). And likewise, even if you've got a decent amount of speed, low RPM's usually result in higher AIT's. My freeway AIT's aren't typically any lower than on city roads since I'm crusing at 2500RPM or so, whereas on city roads I'll at least get up into the 4-5K range on occasion.

But to address your point - I've run a few tests where I've run at high RPM's for longer amount of times. I've usually done this by cruising at 50mph in 3rd gear or something like that, keeping the RPM's at a steady 5-6K. AIT's typically drop by 5F or so since so much air is rushing through the throttle body. However, 5F difference just isn't going to make much of an output difference. To make matters worse, it usually takes a minute to see AIT's decrease that measly 5F. Whereas when you punch it from a red light, your TB has heatsoaked a bit and even a rush of air isn't going to decrease temps by much.

So I think measuring at WOT might have some value, I just don't think it makes a huge difference. As far as the spacers go - I'm probably overanalyzing it. For less than a hundred bucks it's not a bad product. I think isolating heat (or attempting to) is a good thing. But I just haven't seen the results I was hoping to from it.

 

I installed the outlaw IM thermal spacer and it improved my 1/4 mile by .2 over my last visit to the track. The rest of my runs were pretty consistent at 14.8 which was previously my best time. You can see my results in the 1/4 compilation thread in the racing sub forum. I did not get the TB gasket since I did the coolant delete.

 

@losiglow do you have the coolant bypass mod?

also I have a Mag IM and water/methanol injection. So my IAT is lower then the average person. Not significant but its still something.

 

Yes, I've done the coolant bypass mod.

LoL, and I just realized I've been calling it "AIT's" instead of "IAT's" the whole time .

 

^hahaha I didn't want to be "that guy" that corrected you. lol

 

i have these installed with my p2r tbs.. and cai.. had to chop off a bit of my fuse box..

 

Hope no water gets in there. Would you say you've noticed any difference with them?

 

tbh i think i gained some top end. my car lost a lot of low end because i have my exhaust really restricted again because it got too loud. i have 2 resonators. and 1 muffler at themoment. im going to be getting an electric cut out soon. but once i put in the thermo block spacers it seems around 3.5 - 5k rpm it pulls a bit harder. and i can touch the intake manifold after a 85 degree day and hard driving.

 

not sure if you were asking me but yeh
