Happy thanksgiving guys!!!

 

are your marker lights workin? sounds like there's a short to ground before power hits the lights. take out the fuse for your running lights, and press the brake pedal WITH the headlights on. if the lights dim, the problem lies within that circuit.

 

I boosted 10 psi today.....open to atmosphere wastegate is way too loud! I don't like it. Oh well, at least my first WOT tune didn't blow it.

 

yeah blowin an engine cant be fun.. i havent done it yet but its bound to happen.. at least youre not havin a bunch of bullshit electrical problems. are you sayin that the ssq bov is too loud or is it just because its the open atmosphere kind?

 

APEXi N1 ON THE WAY!!!

 

No man, my wastegate is open to atmosphere. In stock turbo Fc's the bypassed exhaust gas is recirculated back into the exhaust from the wastegate. Mine just releases to the outside which basically sounds like straight pipe from the headers. Just wierd sounding, like a race car.

NOOOOO SNOWWWWW!!!!!!!!!!!!!!!!!!!!!!!

 

oh ok.. that makes more sense i guess. so my muffler is on the way and i got a 75mm inlet. thats almost 3in. right? it should be here about mid next week. im excited.

 

Why would you not want that sound of your waste gate it is intoxicating!!!!!!!

 

My muffler should be here thursday. just out of curiosity what happens when you dont have enough back pressure?

 

You make less power.

 

really? hmmm.... maybe this is just for the piston world, but i thought that the better you got the exuast out, the more efficient thus more power...

 

To a certain point that is true but in n/a rotary or piston a little back pressure is needed for optimum power. Unless you make changes to accommodate more air ie boost, nitrous, and or higher octane fuel and timing advances.

You can go past a certain point and make less power rotor or piston.

 

ok thats what i thought. but if i have the presilencer and the headers that should give me enough back pressure yes? Cause i know my muffler has a 75mm inlet which should be just under 3 in.

 

Yeah its not like we are talking 30hp at the wheels here.You got the header instead of the downpipe for n/a?

Haha if so your car might just be louder then the 2. Make sure and hold on to that silencer.


Only way to know for sure would be to dyno.

 

hello fellow montanan's, just letting you guys know i have a forsale thread with some sweet goodies in it... https://www.rx7club.com/2nd-generation-rx-7-1986-1992-parts-194/fs-superstock2s-christmas-sale-infini-nardi-apexi-hks-greddy-more-804356/
and that i also have an 87 turbo II parts car i'm trying to get rid of/part out. let me know if you guys are interested in anything.

 

well i dont have the header or the presilencer yet. they are next on the list though if i can find someone to buy my rims and seats.... so basically my setup for a while is gonna be nasty *** clogged cats and shitty stock exhaust manifold. did i mention my car has been idling like **** lately?

 

I got my muffler yesterday and it is a 3in. inlet. but i think ill be fine. im just gonna run it with the stock cat and exhaust manifold for a while until i can get the racing beat header and presilencer.. haha unless someone wants to spot me money for them

 

ok so i got to thinking and i know the header and pre silencer bolt up to each other but how am i gonna get 3in exhaust pipe to bolt up to the presilencer? because if im right the pre silencer is 2 1/2 in.

 

I would say I would buy the 3inch inlet off ya but I don't really want the N1 unless its the Titan. You will have to have a peice of pipe made to connect from the presilencer to the muffler anyway. They will just expand the muffler end of that pipe and connect your muff by inserting that pipe into your 3in inlet and making it a little smaller then 3 inch inlet.

 

ok. so it will definitely fit then? i talked to the guy and silent knight and he quoted me about 100 bills. do you think quality would be a better price or do a better job?

 

hate...............this..................weather.. ................must.......................drive.. ................7............ .. ... . . .

 

i agree.... i hate having to drive mine in this weather though.. i feel like im being mean to it

 

I would be afraid to even start it up in -25 weather. I just feel like the apex seals are screaming: AGHHHHHHHH!!!!!!

 

so... bad news... i'm pretty sure i blew an apex seal today. anybody have an extra s5 na or t2 block? i'll give ya two for yours! well, an s4 na and my s5 na. both have toasted apex's on one rotor.

 

Hey any FD guys out there i know there are mybe a handfull of them in montana??? It kinda sucks i am the only one in the valley that has one!
I know there are prolly three in missulla, and i went to an auto cross there and i didnt see any rx7s kinda dissapointing.
