Standalone is def the way to go. It's not hard to install if you just do the straight plug and play, wasted spark makes it a little harder but not much, you just have to mount a new coil and figure out distributor block off.

You can just get an old MAF and hollow it out for pre turbo intake, but I wanted to make something. Or hollow out AFM for stock look, which is on my list of things to do around November of this year.

Power wise it dynoed previously at 353WHP on a mustang dyno, so I can't imagine it won't go up a little. I'm not running higher boost, but it does breath a lot better, it hits 17psi at 3000rpm in a 4th low rpm pull.

And yes SamGrant951, Peep is very good with questions, even the hundreds of dumb ones I've asked him!

Thanks Peep. Ive been in contact with him and we're on the same side of the Island also! Just in case old sensors were worn, it would be good to have an option to run an aftermarket setup. This will definitely be my next mod. Thanks for posting this thread.

Oh and SamGrant951 it's 'ALT B'

SamGrant951 04-07-2017 01:43 PM

Awesome, thanks!

re: making a pre-turbo intake / using an old MAF, I had Tim @ SFR make this one for me.

Sam that's a lot prettier than mine!

November = smog test? Has anyone gotten one of these through Ca dyno-smog yet? In principle it could be better, but Ca can be difficult. It may help that most folks have no idea what these look like under the hood, but the coil pack and K&N could trip them up.

what are the costs for these setups?

Contact Raceboy - I believe he has a stealth setup as well, where you can hollow out the stock AFM / Barn door.

MAP sensor location?
 
Sam and Sam
Where did you put the MAP sensor? I think I see a longer banjo bolt on Sam-LA's manifold. Is the MAP hanging from a short bit of hose from that? Is there a max length of hose to avoid delays in response?

thanks
Gary

SamGrant951 04-26-2017 11:09 AM

MAP sensor is within the VEMS ECU, just run the KLR line already in the cabin/footwell that went to the KLR to the VEMS box. IAT sensor goes in the intercooler pipe (pictured above) which has a provided plug in harness that goes to the old AFM plug.

NCLA951 04-26-2017 01:57 PM

I used the 4 port banjo from LR when I redid my vacuum system, to give the cleanest signal to as much as possible direct from manifold without many Ts. Line to VEMS is direct from that. I also eliminated the T from the brake vacuum line and ran that from one of the ports.

V2Rocket 04-26-2017 02:19 PM

I don't remember how the 951 is plumbed but I put my MAP sensor line on a Y right at the throttle body, the same port that feeds the FPR/FPD.

951Gary 04-27-2017 11:34 PM

thanks
 
Sam and Sam ... thanks, I hadn't realized it was on-board. Sounds like is trivial to move from KLR to VEMS input.

thanks
Gary

Hey Sam, quick question, what hole did you use to run the plug connector for the wideband O2? Is there one big enough on the firewall?
