Need a New Lid (larger)
damnit the clear lid is only 74mm?
how much is that??
Okay, so tell me this, is the 74mm lid gonna limit my performance that much? or is it not that bad?
The SLP lid I have also has the SLP CAI under it... and K&N.... to a 85 MAF(soon the be replaced with just a straight bellows) and aa bellow to the TB (95mm PTM)... FAST 92 unported...
with this setup is the SLP lid robbing me of airflow , enough to make more power?..

keep in mind that 90% of people on here are using lids and are just fine with them... if it were me, and I was in the market for a lid, seeing many of them in person, I really like the FT's lid... I saw a buddy at a car show the other day that had one and I have it a few look overs... it's a nice piece...

Nice piece, but from this thread....seems like they have some fitment issues.

As someone else mentioned below, as long as the epoxy that is used to joint he two pieces does a good job, there will be no problem. We haven't had a single lid come back to us yet for the epoxy coming apart. Our lids are very high quality and everyone that has purchased one has been happy with them.

Considering you are well above the 400 RWHP mark, it would be a good time to upgrade to the 85mm Lid and MAF.
The clear lid or the Fast Toys 85mm lid are the same price at 129.99
We also have a reducer for our 85mm lid so that people can use the stock MAF and then as their power levels increaes, they can remove the reducer and upgrade to the 85mm MAF or go speed density without having to buy another lid.

I guess I should use a 85mm lid then, shouldnt I? Well now tell me this, how much power gain, should I realistically see, and will I lose ANY(if at all) low end power?? even at idle??
Lastly, would this affect my current tune one bit? (im tuning it on monday)
if you dont know the answers, then just dont answer, Id rather have honest, facts vs bs trying to make me feel better..
thanks.
Im gonna go with a lid, straight bellows or something to the TB...

Bolt on and cam only cars : .7-.9 MPH
HC Cars: 1.0 - 1.2 MPH
You shouldn't lose any power or affect your tune. The computer is still metering air through the MAF. Of course if you switch to the 85mm MAF, you will need a tune on the MAF table to work properly.
We've never tested the lid for HP improvements using the reducer but since you would be limited by the same MAF size, you likely would not see significant power improvements over another aftermarket lid.

We can't give you an exact HP gain but I can tell the the 1/4 mile improvements people have seen using our lid and 85mm MAF

But as I mentioned previously, Im ditching my MAF, my MAF isnt even plugged in now... its just on.. Im using a SD tune...
You should see an even larger improvement with SD since the MAF would no longer be a limitting factor. You could run a straight 4" hose from the lid to TB
My Fasttoys 85mm lid has been sitting in the box because I didn't realize I needed the reducer to use the stock MAF. I've been running OLSD for years, just never took the stock MAF out. So I don't know if I'll ever entertain putting a MAF tune back in it
1) What kind of 4" hose are people using to mate the 85mm lid direct to a 90/92mm throttle body?
2) Same type of hose needed to go from a 85mm MAF to the 90/92mm TB?
3) The SLP 85mm MAF is supposed to be OEM compatible, does that mean that in theory you can use the stock MAF table with it?

1. We recommend the not reinforced (no metal refinforced inserts) soft silicone 4" hose. The lack of the reinforcements will allow the hose to be stretched a bit.
2. It's an oddball size. Not sure what suppliers people have found for that.
3. It "works" but is not optimal. It's really a short to shift the MAF table by the use of a resistor. You should get a proper tune to realize the best and safest results.
I will be testing these theories, experiences out tomorrow. as i am installing my FAST 90/90, 85mm MAF(Delphi), FT 85mm lid, and a nice re-tune... Should compliment my G5X3, LS6 heads nicely.. I'll post up results tomorrow..
