Powerful LS1 motors require higher airflow than the stock air lid and
MAF can provide. Until now, you were stuck using a small MAF or a
reduction coupler with an 85mm GM MAF. Both of these restrict airflow
and cost you horsepower.
The Fast Toys High Flow 98 mm Air Lid is the highest flowing air lid on
the market and the only one that works with a GM 85mm MAF with no
reduction coupler required!
The Fast Toys high flow lid features our exclusive "Power Bulge" design
to increase the air lid volume substantially and provide a smooth air
flow transition flow from the horizontal air filter to the 85mm MAF
sensor. This lid installs on the stock factory lower air filter base. An
85mm MAF is required (sold seperately). The Fast Toys high flow air lid
can also be used with the stock sized MAF or our Fast Toys Ported MAF
ends with the purchase of the MAF adapter gasket (see below).
The Fast Toys High Flow Air Llid will work on everything from stock to
highly modified LS1 motors. Best results will be on the modified cars
that require more airflow than the stock lid and MAF combo can provide.
For the ultimate performance, use the air lid with our Fast Toys Ram Air
Kit (FTRA). Why waste your money on a stock sized air lid that you will
eventually have to dispose of when you need to upgrade to a larger size
MAF or Speed Density tune?
2000-2002 cars will still be required to use a K&N breather filter for the smog pump (available at extra cost).
Why Use The Fast Toys 98 mm Air Lid & 85 mm MAF?
What people commonly refer to as an "85 mm MAF" is actually larger than
85mm. The OD is actually 96 mm and the ID is 90 mm. Starting is 2001, GM
added the 85 mm MAF to it's highest performing engines (Corvette LS6,
Corvete LS1 etc). After 2002, all GM V8 cars and trucks use the 85 mm
MAF for better performance.
Unfortunately, 98-02 LS1 Camaro's and Firebirds were stuck using the
smaller MAF which has an OD of 88 mm and an ID of 74 mm. This is not
ideal for the best performance. On our flow bench, the Fast Toys Air Lid
flowed 14.5 % more than the most popular aftermarket air lid!
To work with the 85mm MAF, the Fast Toys High Flow Air Lid features a
giant 98 mm ID. This makes the ID of our lid about 9-10 mm bigger than
other aftermarket lids. Since area is pie R squared, the outlet area of
our air lid is about 20 % larger that what is currently available from
other manufacturers. On our flow bench, the Fast Toys Air Lid flowed
14.5 % more than the nearest competitor!
On top of that, we have significantly increased the overall volume of
the air lid compared to everyone else. Higher volumes support larger
horsepower and torque improvements. The Fast Toys air lid has 14 % more
volume than the most popular aftermarket lid and a whopping 27 % more
volume than the stock lid (baffles removed)!
Testing on a mild cam, bolt on stock cubic inch motor, the
installation of the Fast Toys 98 mm air lid resulted in a .9 MPH
increase in the quarter mile! Stroker, heads/cam and more powerful
motors will benefit even further from the increased air flow. Imagine
what motors running speed density tuning without a MAF can gain!
The Ultimate Air Lid For Speed Density Tuners
For those of you that have moved to a speed density tune (SD) and
removed the MAF sensor, this is the perfect air lid for you! Connect the
Fast Toys High Flow Air lid directly to your throttle body for the best
flow possible! The OD of the Fast Toys 98mm Air Lid is 103-104 mm.
No IAT Hole
Most 85mm MAF's have a built in IAT (incoming air temperature) sensor.
Because of this, we do not pre-drill an IAT sensor hole for the factory
detached unit. This gives you a nice clean installation! Instructions
are provided for those people that will still be using the factory
