Nerd-O-Scope: Keeping the Energy In Turbos Using PTP Turbo Blankets

Everyone who has been reading MotoIQ has heard me say it time and again, heat = energy. Why is this especially important with turbos? Because the turbine wheel in the turbo takes energy out of the exhaust flow to spin up the compressor. The more energy available for the turbine to grab means there is more energy to spin up the compressor. Here is the proof.


 

 

It's All About the Zinc - High Stress Wear Resistance with Penrite Oil!

by Mike Kojima

We get a lot of oils and lubricants to evaluate at the MotoIQ office and for the most part we have had good results with the latest high quality synthetic motorsports oils that come across our desks and into the crankcases of our various race and project cars.  When it comes to quality oils we get pretty uniform results, clean burning, low deposits and good wear of the engine's internal components.


 

Building the Ultimate Turbo Small Block Chevy Part 2, The Making of 1100 Hp!

by Mike Kojima

When deciding the best way to power Daren McNamara's Formula D S14, Team Falken decided to plow into new territory with not just a turbo, but a turbo V8.  Not your typical Chevy LS V8 either, but a blast from the past old school Small Block Chevy.  In our last edition of building the ultimate Small Bock Chevy, we looked into the developments that had been made to the venerable 60 year old design to update it to modern standards, particularly the bottom end. In short, the improvements were mostly moving the cam upward to allow for more stroke and to shorten the pushrods for less flex, and a general beefing up of the lower end architecture to support today's power levels.


 

Building the Ultimate Turbo Small Block Chevy-Part 1

by Mike Kojima

The Small Block Chevy is a dead outdated hunk of iron that is best left to old guys puttering around restoring muscle cars in their garages, or is it?

The venerable Small Block Chevy was first introduced to the motoring public in 1954 and was installed on the assembly line until 2003 and is still in production as a replacement motor.  This means that the good old small block has been around for 60 years, making it one of the longest lived and most produced engines of all time with over 100,000,000 being built to date.


 

MotoIQ Wrench Tip - How to Gap Piston Rings

by Mike Kojima

Setting the gap on your piston rings is an important step to building an engine that performs at its best.  Getting your piston rings to have the optimal seal is perhaps the most critical aspect of good engine building.  Of course you want to spend time assuring that your machine work and cylinder wall finish is correct for the type of rings used but a lot of people neglect blueprinting the ring gap.

More than just “bigger is badder”

by Pablo Mazlumian

Check out why the Supra decides to chill behind an ETS intercooler. It's more than just about "bigger is badder".

by Pablo Mazlumian

With all the parts needed to move forward, Project Supra is now on pace to get fired up!  Not only are previously featured parts installed, but we continue to add new stuff as well.


 

Project E46 M3: Part 3 - Headers, software, dyno testing and more!

by Pablo Mazlumian

Aspiring to achieve 100whp/liter from this 3.2-liter, we put more performance upgrades to the test on the dyno and in real world performance situations.  If you like dyno graphs, acceleration times and videos clips, this is a must read!


 

Project Supra Part 5: Thermal Coating, Wrapping, and Engine Assembly

by Pablo Mazlumian

A notable tradeoff to turbocharged power is the potential for more heat in the engine bay, leading to less-than-optimal power and increased turbo lag.  Find out how we minimize these fun-killers.  Our cylinder head and built short block also come together, and we show off the variety of MKC-tuned boosted cars.


 

Project Supra Mark IV, Part 4:  Turbo Components

by Pablo Mazlumian

Some of the most exciting products to feature are turbo components.  We choose some of the best turbo, wastegates, intake manifold and exhaust manifold components in the industry in pursuit of a streetable 800 whp with our 2JZ.
