Am I the first Pettit SC RX8 with a header?

Well, I think so unless someone hasn’t said so. Anyway, see pixs of my new ExoticSpeed header before and after wrapping it with heat wrap. Initial butt dyno indicates an improvement in WOT response and exhaust tone now is similar to a NA 13B engine with a RB header + RB exhaust system. Basically like my old 88 GTU RX7. Only a dyno will truly indicate if whp went up and how much. I’m driving my car to Orlando tomorrow morning roundtrip with the usual but no mandatory I-4 130+ mph sprint.

sweet juan---i have been thinking about just the obx header since "tuned" headers are mute point for our zero overlap engine. that is one beatiful piece. too bad it has to be wrapped--but that should help with some of the underhood heat AND some of the heat soak in the lower intake. I have a little concern about burning up the front o2 sensor(by wrapping) but I really dont know.
I have been speaking with Snow performance some and we are contemplating trying to custom fit(data collecting) nozzle placement on our set up. We have such long intake runners, the methanol may play a more important role than in other set ups. It seems the water can actually evaporate before getting into the combustion chamber if the nozzle is too far from the port. Thanks for the work you have done on the dyno--i am using it.
One question---are you seeing any increase in psi when you use the pre blower nozzle?
Oh yea a little hint---whenever you want to clean your engine just set your controller so that it will spray continuously---i used a gallon in 10miles! Cleaned the Hell out of it!!
Are you using the w/w fluid + HEET?
Now that you are back i will ship the a/w cooler to ya. Hope yall had a really good time on your trip.
I am working on the lower intake--there are ridges to smooth out+ some other secret stuff--for instance --why do we keep the secondary valve?
The vdi valve does not seat properly allowing a very small amount of leakage so i am JB welding that and them smoothing it out.
There are casting parts of the intake that can be removed so it can ventilate better and combat the heat soak thing. I may end up ceramic coating it inside and out. Dont know yet. And i am really looking for a heat spacer between the intake and engine like the Honda/nisson guys.
I am beginning to wonder if we need to monitor the egt's more so than the iat's since our iat is so far away from the ports.
You know what? I am addicted to this damn thing--- Jesus---we need a support group.
Oh by the way i am getting some blow by from the silicone connector during some high rpm's. Have you noticed how much more the engine moves on the mounts now? it causes the silicone connector to actually "bend" and some leakage. i didnt know that until i move my nozzle and actually saw some w/m on the outside of the manifold.y. the cars motor mounts seem to be softer on compression than rebound causing the engine to give more on the drivers side and rebound less on the passengers side. i am looking for an engine damper and i dont know about the weapon r quality. Know of any others?

Wow OD! Lets limit a couple of questions at a time shall we? I’m working on my summer honey do list and starting a new job tomorrow; therefore it will take a while to go thru your laundry list. Anyways, my trip to Orlando and back yesterday was awesome. The car feels a lot stronger, especially when I smash the throttle. I borrowed Bastage’s scan gauge on my way back from Orlando and I registered 2~4 degrees AIT higher than Ambient temperature at the intake (pre blower MAF intake temp). I was driving with my cruise control set at 77 mph for a good 30 to 40 minutes. Ambient temperature was 78 and no AC. And before everyone ask…I’m running the RB ram air intake and a homemade heat shield box around the intake air filter. (see pix) The AIT after the blower was the normal 20~30 degrees higher than ambient but after the no mandatory but yet joyful I-4 130+ mph sprint I registered 97 degrees AIT. That was 130+ from cruising for over 30 minutes at 77 mph and always on 6th gear. I’m using the snow boost juice and with a 100 ml nozzle at pre-blower and a 60 ml nozzle post-blower. No meth leaks whatsoever. One more thing I noticed after the header install is a quicker vacuum to boost transition. I’ll have to wait until my son gets back from his mom to see if the boost got higher than 9.0 psi since I don’t look at any of my gauges while at drive it like you stole it mode. He acts as my second pair of eyes while I keep mine on the road. OK, last thing, I registered 23 mpg while cruising at 77 mph no AC. Oh, I almost forgot we did a meth kit install on Bastage's car and Swoope came over to provide an ample supply of beer. Thank you so much sir and it will take me a while to finish the left overs. Man I have never seen my recycling bin so full.

"engine damper " = chains?

Just weld the motor mounts. Problem solved.

Juan......stupid question, but is that tie-wrap on the heat wrap only intended to be temporary?

I'll volunteer, just promise you won't get us (mostly me) killed

Yeah, thanks for the beer Swoope, that was bloody cool of you.

Nope, the heat wrap is not self-adhesive. The stainless steel tie-wraps are there permanently to keep the heat wrap in place.

Moon Assad

I just found these, what do you think??

I would ask if you are joking, but I know you aren't really capable of insight or sarcasm.

Actually it would work better if you grew up and learned how to respond without sarcasm. Then you wouldn't get taken to the woodshed.

Welcome to now.

Mazurfer

Didn't notice they were stainless. Should have possibly looked a little closer!

MazdaManiac

iTrader: (3)

That wasn't sarcasm. That was poignancy.
You should learn the difference - it will make your reading experience more enjoyable.


So that's where you and Moon hold your trysts. I was wondering about that.
Must be a dirdy-souf thing.

Moon Assad

O, thanks for pointing that out Jeff, its shows me so much. You the man. I wana be just like you when I grow up, you sexy thang.

Glad to help. I figured your search button was broken.

Now you are getting the hang of it! Bravo!

OH nevermind! You are capable of sarcasm, and apparently so am I.

Juan--i said neg to the obx after a second look--seems their o2 sensor placement is on one pipe only--not on a collector like what you have.
I am so jealous. May have to build my own.

Nah! Don't be jealous. Just be patient and keep searching for a good deal.

Here make them an offer.

No, that was sarcasm. Poignancy requires a depth of compassion for one's fellow man



God, that's an original retort. Back to the woodshed for you, your cheap shots are a little stale.

By the way, how's your supercharger?

MazdaManiac

iTrader: (3)

Poignancy requires no particular compassion. It is alternately "astute and pertinent" and "a quality that arouses emotions (especially pity or sorrow)".

Its excellent, especially without that pesky belt.

zenrx8

iTrader: (4)

No,sorry. It was still sarcasm. Much as most of your observations of other's efforts are "****" (paraphrase) and not supportive, mostly 2 or r3 backhanded and baiting comments for every meaningful contribution you make. By the way, just got the PLX Wideband today, and you're right, it looks the ****.

Follows that your ego leads you to a forum for a product you don't even own or use, yet feel free to abuse.

You have an obvious talent and skill in this arena, but truth be told, I wouldn't **** on you if you were on fire (hope springs eternal).

If you could somehow match your personality to your skills, you'd truly be a force to be admired.

MazdaManiac

iTrader: (3)

As far as abusing the "product" goes - I've yet to ever abuse the "product". It is an innocent.
I save my abuse for the people who designed, built and sold the "product".
And, occasionally, the people that have bought it.

I'm not particularly interested in your admiration, though I obviously already have it.
Don't you find it interesting that a little over 18% of your posts on this forum are responses to me?
Well, you can at least take comfort in the fact that your personality and skill match perfectly in that they are completely absent by any measure.

A statistic that means absolutely nothing when he only has 91 posts in this entire forum, and MM has 287 posts just in the Pettit threads. I bet MM's patting himself on the back or insulting someone else at a much higher percentage.

Since he's got the time to read through 91 posts and figure out that 18% of them were responses to him, maybe he'll have the time to scrutinize his own ~10,000 posts and realize that he probably deserved most of those responses. If only he was capable of pointing the finger at himself, but I don't think his wrist bends that way.
