Guessing ballistic louds. Could probably do a resonator instead though! I'm diggin' the idea factory that is FT86Club.com

Hi Jason,

Thanks for your reply. Im on my iPhone now and will send you an email when I go back to work.

Thanks

email sent Jason.

Thanks

Helmholtz is dialed in. Just right. Still has a great exhaust tone and sports car sound, but dead silent at cruise and running around town. In cabin and out of car GoPro vids to follow.

GoPro died when we went to do the out of car, got it plugged in and copying the in cabin onto the computer right now.

Really happy with the way this turned out. Will contact all people who have downpipes on order to discuss.

I think you'll find that it's a band stop filter.

Looking forward to the Go-Pro vids.

Damn it! You're RIGHT! Band pass would only selectively allow the target frequency and eliminate frequencies above and below, wouldn't it!



What has two thumbs and a stock stereo in every single one of his vehicles?

This guy.

When do you expect the header back to be available for sale?

Just had the general manager from Pedders Suspension here for half the day, we can't wait to make a trip to Melbourne. Thinking about making a trip down around Christmas this year or next (Summernats has been a goal of ours for tens of years) and making some more connections for distributors in Australia. Not sure if you followed our work in the last few months but we have been doing fabrication and service support for the Summit Rally Team (also from Melbourne) in the Rally America series. Looking forward to a lot of collaboration and development with them in the future as well. The connections we have made through Will, Ross and the rest of the team have been amazing. Never would have guessed we would have spent half the day with an Australian suspension manufacturer even after doing the rally car work. Word travels fast!

Yes please make a RHD option for this. There will certainly be interest in a group buy from the AUS/NZ section of this forum...

True story

the rhd option is having an overpipe and downpipe seperately, the over pipe is there because its the only way to clear the rhd steering colum, if you wanted a one pipe you would need a different header facing the other way aswell as a different downpipe facing the other way, and that might not even work, theres no flaw in the aftermarket overpipes just namless wants to make it easier and cheaper for customer so they have made a one piece, sorry rhdrivers

[Nardi330]

actually one piece or not i'm not that concern. 2 piece is probably easier to package for shipping.

2 piece = more flange = more weight = sad god... LOL... One piece please, ill pay the difference

Within a week. We will be looking at other header designs, but we're pretty confident that they will be wild and more expensive - like long tube over the axle designs that nix both cats or less streetable designs that are biased toward big cams and high range power.

And using 'who' in that situation throws off the whole play on words. :-D

Jason

Damn it, well I'll keep waiting. I'd like to keep this car streetable, but I would have no problem with a loopy idle from big cams. It won't see winter use so I'm not worried about that. Seems like your system will give the kind of power increase I want and still keep the noise levels down.


I guess I missed the play on words. not that it matters I was just trolling.

Hmm off topic but you know, I bet if exhaust duration is kept down but intake duration is increased, the idle is probably just fine. The engine should be smooth as normal (I think), just a little down on low end torque. If one insists on changing the exhaust cams to big duration then low rpm will suck. I have no idea how much scavenging does though.

We can still eliminate the flange between the RHD overpipe and downpipe, the shape of the pipe is just different. Downpipe and header the other direction is a no-go, if you've taken a close look at a Suby flat 4, one of the heads (LH) sits back on the block and the other head (RH) sits forward. So the clearance from the head to the subframe precludes routing over there. There is also a coolant line in the way.

Our reason for straightening the overpipe was mainly manufacturability and making the design a straight shot rather than a convoluted compound bend section.

I also wouldn't be adversed to using quick pump down lifters either. As long as it doesn't screw up the cam phasing. Wait and see is all we can do.

Disclaimer: I no zilch about the fa20 valve train but I'm assuming hydraulic lifters are used.

[LSV8]

what mufflers are you using..?

[Fly Guy]

They have their own custom mufflers.

So will you offer a down pipe without the first cat connecting to the longer highflow cat you mention. I am flashing back to the 1zz in the MR2spyder where it was mandatory to get rid of the "precats".

I deal daily driver setup IMHO would be factory manifold, after market downpipe to aftermarket highflow cat, with the +10% torque boost over the powerband and probably longer long term stress on the pistons.
