Ecoboost tuning is becoming very popular and for those pushing the limits these cams from Xtreme-DI that are being distributed by RMB Motor Works are worth looking at. Xtreme-DI states the design is based around working with their upgraded HPFP's (high press fuel pump) for the Ecoboost. ...Published on 02-20-2019 09:05 PM
Great news for those looking to knock some weight off their car. Antigravity Batteries updated their lithium-ion lightweight battery lineup with three options which feature a brand new wireless key fob remote for emergency starts. ...Published on 02-20-2019 08:31 PM
The TVS1740 at the heart of the LT4 is way too small for the big 6.2 V8. Still, it can propel bolt on Camaro ZL1's as well as C7 Corvette Z06's into the 9's. The trap speed shows the LT4 with bolt ons is not all that far ahead of the LT5 stock. ...Published on 02-20-2019 06:21 PM
If you had to double or triple check it was California proposing this idea you are not alone. The idea makes so much sense and frankly is so damn cool it will never make it. California is considering adding two lanes to the I5 or CA-99 that will be allowed to top 100 miles per hour. ...Published on 02-15-2019 01:25 AM
We live in a world where horsepower figures are exploding. Coming to market is a supercharged Mustang with well over 700 horsepower with a warranty (that Ford will even let you drag race/track) that will easily be able to clear quadruple digit output in the aftermarket. ...Published on 02-13-2019 10:42 PM
The TV1740 from Eaton that the LT4 is equipped with from the factory is quite simply too small. Yes, the response is great but it mostly likes to light the rear tires up before dying off up top. Plus it is spun so hard it generates a lot of heat. ...Published on 02-12-2019 11:21 PM
Why? Why not apparently. Ford has so many truck motors available you have to wonder what the point of this new engine is. It is the largest naturally aspirated gasoline V8 in its class and the largest motor for sale now that the Viper 8.4 liter V10 is no longer produced. ...Published on 02-12-2019 10:15 PM
Now, the LT5 will not grenade for everyone at 1486 horsepower but Katech certainly is showing us how strong the platform is and what gives out first as they are pushing the new C7 ZR1 engine further than anyone else. Remember, Katech pushed the LT5 to over 1300 horsepower last month using only the direct injection system for fueling. ...Published on 02-09-2019 06:13 PM
If you felt the 2.7 liter Ecoboost V6 was not worth considering, think again. The numbers BMS (Burger Tuning) just posted on 91 octane (with some ethanol blended in for dyno pull safety) are eye opening to say the least. ...Published on 02-08-2019 05:43 PM
Remember California Assembly Bill 1824? As a refresher, if a Police Officer thinks your exhaust is too loud you get a mandatory $1000 ticket instead of the old fix it ticket. Well, you are not the only one who thinks the policy is just a government overreach to grab cash. ...Published on 02-05-2019 04:12 PM
This is a perfect example as to why you can never replace the V8. Throw on whatever turbos you want to on a small displacement motor but you will never replicate this growl. The Shelby GT500 in 'Track' mode simply sounds incredible. ...Published on 02-02-2019 10:11 PM
This year's list is a couple of weeks late but this actually turned out to be a blessing in disguise with some major automotive performance debuts and achievements taking place just in time to sneak onto the list. Feel free to check out last year's best and worst of automotive performance list. ...Published on 01-31-2019 05:32 PM
This is an impressive Ford Focus RS especially when you take into account the car comes manual transmission only. That means it actually has to be driven. Not to mention this car is on the factory 2.3 liter Ecoboost I4 turbocharger. ...Published on 01-30-2019 06:33 PM
This is so absurd that it is right up BoostAddict's alley. The Cadillac Escalade ESV weighs just over 6000 pounds. To get something this big and heavy running 10's in the 1/4 mile is as American as it gets. ...Published on 01-30-2019 04:24 PM
You might be asking, how is Katech tuning the LT5 when nobody has cracked the ECU in the C7 Chevrolet Corvette ZR1? Well, you will notice this motor is not in a ZR1 but outside of it being tested on an engine dyno. ...
