Has anyone experienced any hood clearance problems from installing Saleen super chargers on their 05-09 GT with stock hoods ?

I could really use some advice and feedback.. Thanks !

 

I didn't have any issues but I also had prothane motor mounts that were 1/2" lowered. I've heard many years ago that with stock mounts you could rub the underside of the hood liner a little bit. And removing the good liner would make it work just fine if you had this problem. But that was here say.

 

Thanks for replying back Gary !

The clearance issue I'm having with the stock hood is it's slightly making contact with the upper intake elbow portion that's attached to the throttle body but what I don't understand is when the hood is closed, there is only about 1/8 inch of a gap above the fender line on the driver's side but the passenger side is perfectly level with the fender..

I also uninstalled the cold air intake and heat shield to see if that would make a difference, and it did somewhat but you could still tell on the driver's side that the hood is still not completely level with the fender..

So at this point, I don't know if even without the cold air intake installed if the hood might also be making contact with the throttle body itself or not..

I also don't understand why only the driver's side of the hood is not sitting level with the fender but the passenger side seems perfectly level..

So I'm debating whether to go with the Prothane motor mounts or would I be better off going with an aftermarket hood instead

 

Yes that's what I heard was that it was basically the very front part of the throttle body that would touch. I bought regular prothane motor mounts and took them to a machine shop and had them shaved 1/2". I think now JDM and maybe Steeda and prothane have motor mounts that are already 1/2" lower when you buy them. I would make sure that's what they are first before I got them.

As far as why it's running on one side and not the other my guess is it's simply the stock mounts being so soft to cut down on nvh and I think they are even hydraulic mounts that when the engine revs it torques and tilts to one side lifting up on one of the mounts and pushing down on the other with an unequal force. The more power it makes the harder it does this. It may be that's it's settling on one side more as a result as it wears on that mount. That's just my hypothesis. I may be full of ****. The mounts is the cheapest route. I actually ended up doing both and the hood with paint on top and the underside was a lot more. But them again it looks better too.

Also lowering the engine 1/2" helps a tiny bit on CG too. That can't hurt.

 

Everything you mentioned I agree with you as I honestly cannot figure out anything else for the hood to make contact with other than the very front of the throttle body itself.. So it would seem to me that no matter what type of cold air intake you happen to be using.. it will obviously not make any difference until lowering the engine by 1/4-1/2 " And the more I've thought about what you said, the more I realize the reason why Saleen does not use stock GT hoods on their S/C equipped models as their blowers were not really designed nor intended to fit a stock GT hood to begin with..

I also totally agree with you concerning the stock motor mounts causing the hood to be off as well.. As your absolutely right, the stock mounts are indeed hydraulic and soft as hell.. Just as you said they were designed to cut down on nvh..

So this would make perfect sense behind the engine torquing and then tilting up on one side while pushing down on the other causing the unequal force from the engine revving thus resulting in the engine settling more on one side than the other especially if that particular mount is wearing down over the other more..

Anyhow, I'll be following your advice and will either go with the Prothane 1/2 mounts from JDM or go with the adjustable mounts from Steeda as the motor mounts are most definitely the much cheaper option and hopefully that will resolve my hood clearance issues and as you also said, lowering the engine also helps a bit on CG as well..
