oh yeh, and the definition of a muffler is a device the contains a series of chambers or baffles, thus reducing 'excess' noise, but i think 'excess' exhaust noise it that measured louder than 95dbs...

tworotorguy 04-22-07 09:08 PM

anyone who might know more about all this feel free to correct me, but i been tryin to keep up with the laws to prove ignorant people wrong... ( ie. 'certain' NH inpection stations)...

Dom_C 04-22-07 09:10 PM

Yea thank god I sold one of my 7's to an auto tech, that works at an inspection station. . lol So no problems for me getting a sticker this year!!! wooooo yeaa Hopefully anyhow, my car will most definetly be retardedly loud this year.

tworotorguy 04-22-07 09:15 PM

haha, thats cool, i havent had any problems yet either (knock on wood) but i know some people that get turned down left and right, seems like every year it gets harder, but im sure i'll be fine, i just wish some people would stay up to date on the rules, but oh well, if it boils down to it, i wouldnt hessitate to through on the stock pipes just for the day!

boriqua51371 04-23-07 01:29 PM

the good thing about fb's is that they have no clue on this vehicles also since there are no factory ecus to measure emissions i have no problems getting inspected my exaust is 3'' from turbo back with 3'' round muffler acting as a cat but is straight through from magnaflow and at the end i have a similar muffler. being turbo charge its not loud at all but when the westgate opens well thats another story.

AND Flames :)


also, my best friend is a cop, he said you can still get a ticket for loud / modified exhaust, depends on the department who's writing the tickets. his chief gets pissed if they write crap like that.. one town over though.. i dont drive in :(

tworotorguy 04-23-07 04:36 PM

yeh i know all about that. im not a big fan of each officer/department having it be their own disgression, hope i spelled that right! lol, but i know thats the way it goes.... i definitly have gotten the 'defective equipment' ticket for my exhaust before......!

RotaMan99 04-23-07 07:13 PM

Same here. Except I don't think it was called defective equipment. Maybe sound polution :)

I built my exhaust system and it seems or atleast was very quiet. The muff I used burnt inside so I now have to cut it open and repack it with steel wool. Anyways, with my new exhaust, I drove past a cop on the Everet Turnpike just about to go through the tools in bedford at around 5000 rpm I think. He pulled me over and said my car sounded like a tank :)

I took that as a compliment! Since they usually have over 1000hp if I remembed correctly.:)

He also said, "You have a whole in your muffler?"
Me, "Nope."
Him, "You sure?" (Smirking like I have no idea WTF im talking about)
Me, "Yes im sure I don't have a hole in my muffler, I built the whole thing, and the muff happend to be fiberglass packed and the FG burnt out so I now have to cut it open and repack it."
Him, "ah umm ok" (With a confused look on his face)

He just gave me a verbal warning.

tworotorguy 04-24-07 07:24 PM

boriqua51371 04-24-07 10:13 PM

I was wondering if anyone here knows about a guy who lives in pittsfield he has 3 FC's parked out near some tractor trailers and I heard he has a fully built SCCA FD????

yeh, i been askin about those for awhile now.....

grade247 04-25-07 08:42 AM

Yea my buddy dan who is on the 240 forums and I know him personally said he knows a kid that works with the guy that owns them but his is a pot head and an unreliable contact to get to talk with this guy. They all look like they are in good shape.

RotaMan99 04-25-07 10:53 AM

At my work i met up with a guy who stopped me before leaving and told me that my exhaust sounded familiar. He then told me he has 4 rotary engines in his shop because people use them for airplanes :). I work at the nashua air port. I asked him if he had any turbos or manifolds. He does :) but no intercoolers. Anyways, if any of you need parts, let me know and I will see if he will sell anything.

boriqua51371 04-25-07 02:22 PM

do you know if they are 13b or bt or 12as ? i would pick one of this up .

RotaMan99 04-25-07 06:33 PM

let me think..... I believe he has 3 13b and 1 13bt. I will have to ask him again next time I see him.

CrackHeadMel 04-25-07 06:42 PM

Find out what he has! im always intreasted in diffirent things.

What kind of turbo's ? im still waiting for a decent sized VNT unit

CrackHeadMel 04-25-07 07:51 PM

Got the rx7 fired up!

It keep afterfiring however i realized that now that all the vacume leaks are fixed.. takes way less fuel to start (almost 2ms) backed the starting timming from 19 to 15 and it started for the first time in 4-5 months on the 5th crank on a jump from my subie

smoked me out of my temp garage with 11.0 idleing afr's.. got them to 11.3's with an almost solid 850rpm idle w/o the idle air controler hooked up and my compensation maps still jacked from the last time i drove it in the fall before i got to dizzy to deal with it anylonger.. however tommorow (if i can find my damn licenceplates) ill pull it out and wash it woooo

HOWEVER.. this is the first time in the history of my car that i maintained a low idle..what kind of oil presurs should i see around a substained 800rpm.. i was getting just under 30 with old oil that ishould probably change because i think it got some coolent in it (oil return hardline was just under lower rad hose and i know it splashed once) im chaning it tommorow so dont worry :)

Thats sounds like the pressure I used to have back in the old days.

CrackHeadMel 04-27-07 06:41 AM

Do you mean that in a good way or bad?

I dont feel to bad about my pressure now, buddy of mine pickedup a 88 gxl, came to my house last night to swap on my wheels (one of his are bent).. zero oil pressure at idle.. after i added a qt of oil it had some.

180K on original motor, i think its tired

RotaMan99 04-27-07 10:42 AM

Around 30 or just below is normal for idle. Any modifications to the oil jets?

My oil pressure is always real low to. Around 5-10psi at idle at about 40 above 1500. Its been like that forever. Even tested it with a mechanical gauge. For safty reasons I only run 20-50 year round. The engine I have was said to be rebuilt, but It has a few issues. Im not to worried about the oil pressure problem.

RotaMan99 04-27-07 10:51 AM

If it has no oil pressure at idle, just the front cover o-ring and pressure control valve. Also the pressure contorl valve on the rear housing.

How does the engine run? does it smoke? Hows the compression?

No modifications done by me, and i believe the engine is stock though and through



Buddys engine runs ok, it was neglected by the previous owner and has extremely old plugs, filters, fluids etc etc It smokse a little bit.. however he was out of gas, and all i had was 1gal mixed for the chainsaw ..

we will know better next week

tworotorguy 04-27-07 05:15 PM

yeh, i'll be hookin up my new oil temp and oil pressure gauges asap, when my new oil filter pedestal arrives. be nice to know what i've got goin on more accurately :)
