So I Removed The Airbox Lid.......

[Almost Tactful]

Damn, these things sound wicked up high lol! I went for a short cruise this evening and I decided to let the engine growl and wow was I impressed.....makes me actually want to drop the cash for a CAI for the sound alone, it's nutz! I got home and put it back on right since I know sucking all that hot air can't be good performance wise, but still it was fun

[Kalm_Traveler]

I did exactly the same thing - had an AEM V2 in-hand within a week hehe

Great timing, I'm still stock with my 07 but thinking about things to do. I was in a bar parking lot the other day (for food!) and a guy working outside chatted me up about my "s2k". He said his friend does lots of drifting with his, and I asked about mods. The first one was to remove the plastic intake manifold cover, he said it made it way cool sounding. I hadn't heard about that before, so now that you've done it, and ask a good question about heat, what's the general opinion here about it? I know, JJ, I should search the threads, but I'm tired...

Heh I'm starting in the other end.
In the market for an Amuse dual Ti exhaust

[Almost Tactful]

I was thinking about exhaust as well but I would want a tuned sound and not that loud crap I always hear.....

Physics-wise, the hotter air that you'd be sucking in that way will actually reduce power a bit. If you then switch to an AEM V2 the change in intake temps will be enough to notice the difference

[yellowbird]

Have you found that tuned exhaust and not the same as you hear on utube ?

[Seattle2k]

OP, yeah, I did the same thing, after somebody mentioned it. Fujita F5 is now on the way. =)

[icmhonda]

amuse. big $, tuned sound ,amuse.

Tell that guy that we do not have a plastic intake manifold cover. We have a plastic injector cover that also happens to cover part of the intake manifold, but removing it wouldn't have any effect on heat or sound.

For the open lid airbox, how loud is it at 4,500rpm and up? I've heard about this, but never done it. I'm going to try when I get my camera mount back from a friend.

[desmo4]

Metal tube intake manifolds are junk. Honda used plastic for a good reason. In the summer you can fry eggs on a Fugita F5. If you go with Mugen or Comptech you will get cooler air and no chance of sucking in water which will destroy you engine. And a full Mugen system is a tuned system.

Then go with the ARC airbox. It's the most bad ass airbox for the S2000.

SC. You'll want it sooner or later, might as well save yourself the trouble.

What with all the talk of hot air and h.p., I thought I'd cross post this. If you read it you'll see that the hotter his car was the faster it went. This was 1965.

I am sending my favorite picture reflecting the end to a perfect week at Bonneville. The date was August 1965 Saturday afternoon the last day of speedweek. There was very few competitors still running at this point in the week. This gave me a chance to make several back to back runs. As I continued to run the engine got hotter and hotter, little did I know that that was what was lacking in previous runs was more heat build up in the engine. The last few runs as the heat gage went up five degrees the tach reflected another 100rpms. The final run engine turned 7200 rpms at 220 degrees. This got me to 180.09 in the last timing trap. Engine was a factory crate 327 which I had torn down to add more clearance to the piston to cylinder walls. It had a light weight fly wheel, two 4 barrels and a crowler cam, 4 speed transmission and a 3.06 chevy/buick rear end.

With the help of my family, wife and 2 kiids, and my best buddy John Stager we packed up in Sacramento, the family station wagon complete with push bar, tools and what room was left over was filled with food and beer and tow bar. The Healey ran like a dream on the way there and home but stopped at most every gas station. John and I took turns driving the Healey and it was great fun.

The height of that years effort came to light at the trophy presentation in LA January 1966 when they called my name, I came to the stage in front of some of the most prestigious Bonneville racers of that time. They presented me with the class award and the Chuck Bennet Award for the fastest car ever driven to and from the race and to win the Class.There was a standing ovation and to this date I choke up just remembering it. Went on to go to show the car in autorama here in Sacramento two years running. Have some nice trophys and memories to look back on. Please thank everyone for their inquiries. And thank you for passing the information on.

Your Buddy,

Jack

cold air is denser it makes more power its a fact.

[Seattle2k]

Thanks Philiam. A hot engine and hot intake air are two different things.

[philiam]

Not making a statement, I just threw it in for the sake of conversation. Remember he wasn't injected. The jetting might have been off in the carbs and the leaner mix burned better. Just food for thought.

I just installed a comptech intake on my car and I am not impressed. The fit isn't that great. Not really any louder than stock airbox. I wish they made a "whale cock" type for the s2000, it did wonders for my GSR & Si. I am not knocking them as a company, I am sure they make other great products. I think I am going to switch back to the stock airbox and maybe take the lid off once in a while. I have a Berk Test-Pipe and feel that was money better spent. I think the engine looks better with the stock airbox, not as hacked-up. I am sure that others may feel different.
