Installing a bored out throttle body is a very cost-effective way to bump up the performance of your Ecotec or L67 supercharged 3.8L V6 engine by increasing airflow by 14%.

Designed and manufactured by a team of qualified mechanical and automotive engineers, so you can be assured of the outstanding quality and workmanship of these throttle bodies. The photo does NOT do these throttle bodies justice!

Through different testing procedures, gains of around 10hp at the rear wheels have been recorded if used in conjunction with extractors/exhaust and cold air intake. A greater power gain can be achieved with additional mods such as a larger cam and supercharger etc.

On top of this power increase, it will also make your engine sound meaner (i.e. more air rushing into the engine) and offer a much better throttle response.

On another note we don't manufacture these throttle bodies in 70mm as we feel that they are unsafe in long term since the wall thickness is too thin and may fail over time.

These throttle bodies have been fitted to a number of cars including David Wilzig's ITT.38L, which was the FASTEST V6 IN AUSTRALIA, pulling 9.981 seconds @ 137.88mph down the quarter and making 750hp! So these products have been well proven to work even on the most extreme cars.

 

 

As you can see on the before and after dyno graphs, a VY Commodore with manual transmission, extractors/exhaust and chip have made 161.2hp at the rear wheels. After changing leads, spark plugs and installing our larger throttle body power jumped to 176.9hp at the rear wheels.

 

Power Run - Standard Throttle Body

 

Power Run - Larger Throttle Body

 

Please note that our throttle bodies use a brand new 69mm brass butterfly to match the bored out throat. Other products on the market are merely a cleaned up version of the factory item and still use the original butterfly which leaves the main restriction to airflow in place. This is done to mislead people into thinking that they are selling a larger throttle body when they actually are not! To be sure, it is best to ask for photographic proof that the butterfly diameter is what they claim it to be.

Notes:

  • These throttle bodies are not polished.
  • Vehicles equipped with automatic transmissions will require a tune as the shift points are altered by fitting this throttle body. We can provide a re-calibrated PCM or memcal to suit.

Good to have if you've never seen the iTEP exam, but don't rely on it to boost your scores
Format: Paperback
This book is good in that it comes with two practice tests: one in the beginning of the book, one in the end of the book. The grading rubric is helpful too. However, the actual guide part of the book, doesn't help too much with how to improve test scores. What I like least about this guide is that it won't tell you which questions you answered incorrectly on the practice exams. A good test prep guide will tell you what you answered incorrectly, and will tell you what logic to follow to get to the correct answer. In the reading passages, it would be nice to know where I can find evidence to justify the "correct" answer. In the grammar section, it would be nice to know which rule I'm violating. Any test guide should always come with some testing strategies. I.E. If this question is taking up too much time, skip it and go to the next one. This guide lacks simple strategies like that. Simple strategies like that could be useful when incorporated into this guide because there are certain sections on the exam that you can go back to previous questions, but some sections where the "back" button is disabled. Overall, if you've never seen an iTEP exam before, this book is certainly helpful in that it will give you an idea of what you will be testing for. However, this book alone won't help you achieve a score of 6. The table of contents itself will tell you there are only 86 pages of actual content covering test material. That's not enough to cover how to excel in the exam.

Don't buy it
Format: Paperback
It does not prepare for the real test. Using it is absolutely not enough to be approved with good grades. Too expensive for what it offers.
