Another problem with them.

All that money --- and no gain.

But you do get - persistent boost leaks and the eventual complete deterioration and loss of sealing..

 

i was going to buy one anyway, the reason is 3 or 4 degree's cooler, 1 less count of knock, 1 extra psi of boost = Powa!

 

i put outlaw engineering spacers on my 4th gen eclipse and i loved them! i actually buttdynoed some hp on the top end. but i did have a short ram intake, shorty headers and a catback exhaust

great mod! im surprised im the only one who seemed to have a good experience with them. but i guess you guys are all turbo lol

on a 3g Eclipse GT: RESULTS: maximum gain 6.4 whp and 9.5 ft-lbs of torque.

 

We did a direct comparison on the runners of my buddies Nissan SR20det motor. Each runner on his car was 40 degrees cooler. Measured with one of those thermal reading guns... I can get the exact readings if neccessary.

 

i have one on my car but i don't have IATs before and after. I also removed my EGR, not sure if other who haven't seen gains have. EGR might be heating up the intake mani before a pull, not sure.

 

For the discussion between Itune and Rouge. I think your both right in a way.

First, Itune is from hondas. All motor hondas need ever lil HP they can get. I believe on those application that this IM gaskets may make HP and are not that much of a hassle.

Now for Rouge's side, on a boosted car, I dont think it matters much. First, like rouge mention, we have boost and those type of IM gaskets have been know to leak. Also, on a turbo charged setup like we have, there is a lot of heat generated and I dont think the IM gasket helps much. Most likely it will melt, like mentioned. And in turbo world, we can make a lot of HP gain out of one cam/turbo change and dont think the small gain (if any) from the IM gasket is worth it.

 

Mine has been on my car for about 70k or so. No leaks whatsoever. IM went from too hot to touch to being able to hold my hand on it with no issue.

Not sure on any HP pick up but mine has not melted, EGR hole is not pluged, and all EGR stuff remains in tact for now. I have the Hondata one I think I paid 40.00 for it.

 

You are correct, to a certain extent. While i am from the Honda world originally, most of my tuning experience was with turbocharged/supercharged Honda engines. I was one of the first to ever turbo a k20a2 rsx-s engine, i did R&D for GReddy and tuned/did R&D for Hondata. I also helped develop the Hondata k-pro standalone ECU and tested many of Hondata's heatsheild products on several vehicles, including the RSX, TSX, TL, to name a few, 95% of which were not naturally aspirated. I always saw a reduction in intake manifold temps, which always lead to increased power.

In a turbo charged engine, you will not have a vaccum in the intake manifold, under boost(obviously). Under boost, this means that intake charge air is sitting in the manifold as long, if not longer than if the manifold was in vacuum. Heat is going to be transferred into the charge air, as it's forced into the intake plenum/runners and awaits entrance into the combustion chamber.

Look at it this way, if this science was not correct, why do tuners place bags of ice on the intake manifolds when looking for big numbers on the dyno? If this made no difference on turboed engines, then how do you explain the increase in power?

Oh yeah, i have never seen a intake spacer fail..btw. Not even on a EGR enabled Evo.

 

Okay. I didnt really wanna dive that much into it. Was just commenting, trying to keep both sides happy

Ps since we're bragging (just playing ), I was supercharging/turbocharging hondas before there were K series, RSXs and TSXs.

 

Trust me...my post was not a dig on you. I just felt, that if my experience was called into question, that it should be known who i am.

I was around before the k-series as well. I just became known for my work on the k-series engines.

 

I know i was just playing around. For some reason Im on a humor, fun tip today.

I didnt get to play with the K series, got into AWD turbo cars.

 

No worries brobot.

While i do miss certain things about Hondas. I never looked back.....

AWD, turbocharged FTMFW.

 

Brobot?? What? LOL

 

The plenum spacers are big in the Nissan community. One of the best mods for VQ Motors.

 

Yeah, but thats because they make the plenum bigger and help the two cylinder in the front breath better. Lil bit different then the thermal spacer but yeah..
