what do u guys think of it???
increase in anything??...like HP?? Torque??...
or is it just for looks and cooling efficiency??

any info would be apprieciated.....thx

Mr Hyde

I think our stock radiator cap is already set to the same pressure specks as the Mugen one, so this mod is as good performance wise as the Mugen oil cap, which I might add I am getting just because it looks so sweet.

Actually the Mugen is rated at 1.3 now to our stock 1.1

Mr Hyde

I was checking online about that one just a few days ago, and I read that on some Honda models especially ones with higher output engines already came equipped with higer rated caps. You sure we are still at 1.1? If we are then going to the higher pressure cap will increase cooling efficiency. How measurable or significant that difference is is debatable.

I wanted one also. How much did you get the Mugen cap for? Also does anyone know if there is an aftermarket radiater and fan that I can buy.

Your thermostat will keep you water temp at a constant reading. There is a product called Redline Water Wetter that helps the water cool down faster when it is in the radiator. Cooling through a separate radiator and fan is useless, because the thermostat will simply close until the coolant is warm again.

Changing to a lower temp thermostat or removing it altogether may not enable the engine to warm properly and may run worse than the stock setting.

I think it's a more cosmetic mod than an actual engine improvement mod. Granted, higer pressure rating should help the coolants cool off faster, but I highly doubt it'll make any difference in your car's performance

Yeah I think its just a cosmetic look more. It did lower the temp just a tad bit. I had the Mugen radiator cap for a long time now. I swapped it after I had my TL-S for only a week (1yr ago). I would also do the Mugen oil cap but decided not to cause the mugen oil cap hella freaken hot if you try to do an oil change!:wow:

Payce~!

I just ordered my Mugen radiator cap and oil cap the other day......should be receiving them any day now Ordered the pedals as well as since i had a few really crappy nights at work and decided to go on a lil shopping spree :p I'll post pics when I get a chance.

ONLY if your car has a habit of puking into the overflow tank. I'm betting that it doesn't, in which case, this mod is strictly cosmetic.

1.1 last time I saw it written on our stock radiator cap. It was a move from 1.0 or so to 1.1. I was thinking of getting the mugen too, but when I noticed that the mugen was 1.1 and my stock was 1.1...I was okay...not going to waste $40 for the exact same thing. But then the 1.3 came out.

where r u guys getting them? can u post or pm me with the location please?

thanks

If you search on ebay, you can find lots of MUGEN oil, radiator caps for cheaper price than kingsmotorsports.

waste of money

This is the first time I've ever heard of people hoping for gains from a oil cap...

I think it's more about cosmetics....The logo does look cool though.

The idea is that this prevents "bubbles" or something from building up in the radiator and thus provides better flow. And then supposedly from the flow, more hp/tq gains. The radiator cap is unnecessary unless you were constantly pushing your car to it's limits or os.

T Ho

Actually, if you had bubbles in your system, inhibiting flow, this would put LESS drag on the water pump, increasing power- at least until the engine overheated.

So, the idea is incorrect. However, as the engine heats up, the ECU does pull back the timing and fuel enrichment slightly, which will tend to reduce power. BUT, this assumes the engine goes above the normal operating range.

I've found that Honda cooling systems, in general, are VERY well designed compared to other manufacturers (specifically the big three- GM, Ford, Chrysler), and, as such, don't really need any improvements. On your TL-S, have you ever seen the temperature gauge move above it's normal position, under any driving circumstances? I haven't. This is the hallmark of most Honda engines- and one of the reasons that wear and emissions tend to be lower from Honda engines than others.

So, just enjoy it for what it is- a pretty cap.
