I was going to ask this in the S550 section, but it’s completely full of ads. So I am defaulting to the cobra roots. I am doing a Gen 3 coyote swap with a Gen 5 3.0 Whipple on the car. Collecting parts and got wondering about the IC system on the S550. I know a lot of work has been done over...

I agree here, have you adjusted the idle screw at all for the TB? I had to adjust my VMP big TB when I first installed mine on my 3.4. if you unplug the IAC will the car start and stay idling? If so it’s getting way too much air through the blade.

Thanks for the info. The car will idle really well for me. Warm or cold it idles well. My big problem is getting it to start nicely when cold without having to add throttle input to save it from stalling. That is my big issue I am trying to sort out now. It seemed like it was too rich at first...

From 3 logs I grabbed yesterday it appears to hold a nice start and idle following the start if I am remaining on idle source 9. When it switches to idle source 1 my rpms immediately fall and the idle starts to surge or stall. When its in idle source 9 its holding around 15 degrees as its...

Sorry to dig this old thread up, but I am having a very similar issue on start up. Car has the TPS set to 0.9 volts(key on engine off), throttle blade has been opened up to allow the IAC duty cycle to be around 0.26-0.3 when warm. Car idles well at 800-850rpm when at operating temp. But same...

Interesting info. My cams are smaller than the stage 2 crowers. I am 225/227 duration with 0.450" lift. I ran the ICL on the intake cams down to 109 and have the exhaust at 115-116 range. My whipple bypass is low operating for decreased vacuum. I see about 10-11" of vacuum at idle. I am going...

This sounds really similar to my issue. Car pulls fine at WOT, no lean stumble or lean tip in when you mash it WOT. Drops down to the commanded A/F and pulls. Part throttle it will stumble and go lean(sounds like its breaking up). I did have an issue with a couple coils going bad during the...

For the very reason you mentioned I literally unplug my primary pump in the garage with a battery charger on the car and use an air compressor to apply pressure to my hobbs switch to ensure you hear the second pump kick in at the correct boost reference pressure. Then verify the same on pump...

Did you end up finding a mount that was more solid? I would prefer to stay poly or stiff rubber vs a solid motor mount, I drive on the street a lot and do prefer it to have some movement if needed.

I have a MM k-member and I squared it up correctly 4-5 years ago when I installed it so I doubt that has shifted, but I will have a look to verify as well. I think its just a piss poor design on the crusher inlet, it should have bent around a bit more for clearance. The IAC is in a shit spot as...

Motor mounts are quite new Energy poly bushings. I can free rev it in the garage and it doesn't even come close. I wonder if I get more movement launching it on the street and on the 1-2 shift if you have to pedal for traction. Stuff always moves differently under full load. This is only my...

Just wanted to post this questions for the guys with Whipple Crusher inlets. I just got back from driving the car and laid into it a few times. Noticed after the one pull my idle was hanging a bit above 1000rpm. Get home, pop the hood and notice my TPS sensor is cracked right in half. Looks...

Sorry to dig this up, but did you find out if it was a tensioner causing the noise? I had a noise the other night that appeared when the car was warm and it had a similar knock/tick sound that was new. I was filming the sound and it stopped half way into my video clip. Cold started the next...

It appears I just need one ground to the small pronge, power to the one large pronge and out to my relay with the other large pronge. Seems to make the relay click and lights the switch when its turned on.

Been doing some searching and was wondering how you guys with them have wired them up. I have a relay for the line lock in my engine compartment already that powers the line lock. I was using a 3 pronge rocker switch inside the car to turn it on, but I installed a double din receiver so lost my...

Just wondering if anyone has the part numbers for the two blue canisters that drop into the fuel tank. I am able to find just a single canister on LMR or Ford Parts. I messaged Steve@tasca parts on here and no reply? Is he no longer around, he was usually my go to for stuff. Was looking to grab...

Same problem I have with my borla tips. I talked to Borla and you can buy new as well. I might just get them off and try to sand all the chrome and crap off to get down to bare metal.

Anyone know where to find the splash screen in this thread. The Ford Performance with the Cobra snake? Sync 3.3 Ford-EVO Startup / Shutdown Animation

I did look into that pump Kevin it’s the one I was hoping to get some positive feedback on in this thread. Most of my researching online did not have good success with this pump. I think I will make the switch back to an intank setup so I can run E85 compatible walbros. I am quite surprised...

Totally missed. I have a sumped tank, for me to swap to in tank I need a new cobra tank, fore hat and pumps. I will be $1400-1700 deep to do that. I was building this fuel system before guys like Fore were making big volume fuel hats for return systems. So you had to put together a return...

I am going to try and finally get on the E85 train, but doing some research and not sure if I am screwed or not. I have a Glenn’s sumped tank with triple walbro GSL392 pumps. These appear to be not E85 compatible. I have had this setup since 2007-2008 when I first went return. I have been...

I hope all works out, I have red flags going in my head with some of the values you have been given is all. You can give whipple a call they should have a good idea for a 4.6L mod motor what blower rpm will be required to get you 28lbs so you aren't throwing money at multiple pulley combos.

Your pulley combo of 4" upper and 6.55" lower is only going to spin the blower at 10,600rpm at 6500rpm. 4.0L whipple is 18k max rotor rpm so you aren't going to be anywhere near 28psi I would think. How was it pullied for the 960rwhp? I have a 3.4 with 3.5"/6.55" and that is 15psi at 3400ft on...

I am curious if you have dyno or track times to show the loss of torque. Be interesting to see if its just a perceived loss.
