There is a need for a much improved intake manifold on TPI engines. The Big Mouth is a simple
bolt-on and uses all of the hardware and fittings that are on a stock TPI manifold. As you can see
from all the test data in our Insider Hints handbook, there are cylinder heads that will flow much
more than the stock manifold can. This manifold makes 15-20 HP on a stock or mild 350 engine.

After porting, grinding, reshaping, and just about anything we could do to a TPI intake manifold and set of runners,
we were unable to achieve a large gain in RPM. The TPI style- intake works excellent for creating a large
area of torque off-idle to about 5000 RPM, but one big disadvantage is it’s RPM potential. If you’re
looking for a flatter torque curve and more RPM from your modified TPI
engine, the TPIS Mini-Ram is the manifold to use. Perfect for a modified
350 or a larger engine. It is also a very versatile way to convert any Small-
Block Chevy engine to fuel injection. The TPIS Mini-Ram is a snap to work
on, it is a one-piece unit which makes injector changes or any type of work
much easier when compared to a TPI-based manifold set-up. The
Mini-Ram includes Throttle brackets for all TPI-equipped vehi-
cles, a thermostat housing, Stainless throttle body bolts, ARP
Stainless intake manifold bolts, TPIS MAT sensor relocation kit,
and Fel-Pro intake manifold gaskets. The Mini-Ram manifold is
2-inches shorter than the TPI intake assembly, which makes it easy
to install in a variety of vehicles.

After working with the LT1 since it’s inception in 1992, we’ve always been
impressed with how well the factory intake manifold works in a
variety of applications from stock to larger 396 C.I. engines, even on
our “King of the Hill“ 409 C.I. LT1s. We’ve found a need for a better
manifold on engines above 500 H.P. The TPIS LT1 Mini-Ram’s larger
plenum, superior port entry design, and longer runner length can deliver
gains everywhere in the RPM range on your modified LT1 engine. The LT1
Mini-Ram shares many of the same dimensions as our original
Mini-Ram used on TPI cars. This means it also has a SBC-
style distributor hole at the rear. This enables you to use an af-
termarket EFI easier and eliminate the need for the GM
Opti-Spark distributor. Accepts any TPI or LT1 style throttle body.

Since the birth of the LS family of engines in the 1997 Corvette, we have spent countless hours test-
ing every component possible on the dyno, flow bench, as well as on the track. In the early
years of the LS1 engine we were stuck with modifying the factory throttle body to find more
power. After trying different things with the factory style throttle body, we cut the nose of a LS6
intake manifold and attached an LT1 dual blade 58MM throttle body with a prototype nose. Our
hunch was correct; we immediately saw gains in many different engine combinations. It
was apparent that these engines needed a bigger throttle opening! This led to the development
of our 90MM throttle body for the LS engine family. With our 90MM LS6 intake manifold, you get the best
of both worlds: A bigger throttle opening with an excellent intake manifold design. These generally work the best
on modified 346 C.I. and 383/402 C.I. engines. With our LS6 Manifold you'll make more power everywhere in the RPM

What we hear from our customers is that they need an exhaust that has a deep throaty idle, yet is barely louder than stock
at cruising speeds, and at full throttle does not draw cops from miles around. So we designed and built a new muffler to
meet those needs. It has an aluminized body, stainless steel sound chamber and four 3 inch polished stainless steel
tips. Unlike others, the over the axle tubing is a full 2 3/4-inch in diameter.
We have tested it against several of the popular aftermarket systems and found that our C-5 system made more
power throughout the entire RPM band, averaging 2 RWHP more than the next best, and 10 more RWHP than the
ZO-6 factory system. The biggest gains were from 5800 RPM to 6500 RPM. The testing was done on a stock 2001

These Pulley Sets are an easy way to unleash more power from your engine. Many engines have accessories that are
over-driven from the factory. While this may work for the average car and average driver, it keeps your modified engine
from reaching its maximum potential. TPIS Underdrive Pulley Sets reduce your engine's accessory drive speed by
approximately 10%. Each kit includes a crankshaft and alternator pulley. The smaller diameter crankshaft pulley slows
the A/C, Power Steering, and water pump speeds.

Our first brake kit is an easy upgrade! The factory 11 inch rotors and single piston caliper are barely adequate for
daily use! Our "Sleeper" kit uses a 12" Corvette rotor as well as the proven Corvette dual piston caliper. This brake
set-up fits inside a stock 16 inch wheel making them un-detectable by the average tech inspector and enthusiast.
   Our second kit uses a 13" Brake rotor and a PBR late style (LS1 Camaro/Firebird) Dual Piston caliper. 17 inch
wheels are required. These are a great upgrade on all 93-02 Camaros and Firebirds and are a must if your do any
track days or lapping events.
   All kits use O.E. Style Rotors, Pads, & Calipers making replacement parts and many different pad compounds
easy to find. Complete conversion kit includes everything for installation - Calipers, pads, rotors, brake lines, and
Grade 8.8 hardware. Installation takes about 2 hours. We designed this kit for the 93-97 cars, but it can also be
used on the 98-02 cars. Bracket kit includes Hardware as shown in photo.

                                 Since we opened our doors in 1988, TPIS has tested hundreds of cams on the Dyno, street and racetracks. We tried many different center-
                                         lines, lifts and durations to develop cams that work in many different applications. You will notice that the lift numbers are modest
                                                      - this will keep the velocity high around the head of the valve, which improves the combustion process. We can also
