I work at Ford diesel powertrain, and we put screens on our intake manifolds. I'm pretty sure the only reason is for sound quality concerns. So long as you don't mind the louder sound, I say keep it off.

That screen is in there to redirect the air to a less turbliant flow. it restricts the air flow by 15-20% that was one of the first things that I did.

OK.... WTF do you have done to your car? for you to not know about the screen, or the exhaust, and aparently you have factory exhaust. what have you done?

I'm pretty sure they are cast. But you could upgrade with the Diamond Coated/uncoated Forged Pistons.

I run 12 lbs of boost daily and doubt I will ever need to upgrade. Most people lose a piston when they run one of the cylinders too lean and crack the piston. One thing that always seems to destroy pistons is when people try to maintain speeds of over 100mph for an extended time period.

Once you get a GP you'll be happy, and I dont think you'll have to worry about losing a piston.


Good Luck

Tim

You took out the throttle body screen? How tough was that? Do you think I'd gain anything on my NA (no supercharger) 3800?

I just removed my screen on a 2001 g.p with a 3.1 and i was sceptical at first about removing it, but now that its gone and i think about it, good idea ! It has to restrict alot of air coming in and thats not good.

Re: 12 Hp After Throttle Body Screen Removed

There have been some guys on www.clubgp.com that have had problems with their cars after removing the screen. Be careful not to destroy it..in-case you have to put it back in.

And as Ripn12s pointed out, there are many factors that could have influenced the dyno results. I highly doubt that removing the screen gained you 12hp.

And the OBVIOUS answer to your question....YES, it would be louder if you removed restrictions in your exhaust.

Re: 12 Hp After Throttle Body Screen Removed

Ripn12s, that would blow a piston if the car is not in high gear, in high gear the rpms should be around 2900 and that would not harm the engine(to my humble knowledge).
The Burning Rom, good to see you again.
Al'scar
If you are going to put a lot if strain on your car go to http://www.intense-racing.com and check what they have for blocks, pistons and heads.
I blew my previous engine but was because I rev it up to 5500 for more than 15 mins(my tranny when to neutral) and it screwed the engine good. But for most of the guys I have read here that have moded lighlty or moderately their cars what the block brings from factory has served them more than well. In my case I am using a Reman Mr. Goodwrench engine with some moding and it only has 2 months so I do not really know if this one will get problems from the moding that I have made to it.

my car is around 3500 rpms at 100...maybe thats because its a gt not a gtp so the gearing is different..

Re: 12 Hp After Throttle Body Screen Removed

gtgp97, Before my tranny died my car was like yours. When I got the new one I got it with the final output gear ratio to be 2.93 instead of the OEM the car had(3.29). If your car has a 3.29 transaxle then is behaving normally if it is 2.93 then I am nor sure because mine increased the cruising speed from 90 to 105 when I lowered the transaxle from 3.29 to 2.93 at 2900 rpms. That depends on the transaxle final gear ratio not if the car is NA or FI. What the FI or NA makes is the car quicker to get there.
