The Supra forums are going nuts because they have a photo of the front of the production version of the MKV Toyota Supra. The design looks exactly as expected. Is it really all that attractive? ...Published on 12-10-2018 07:10 PM
In a drag race, traction off the line is everything. If you want to improve your elapsed time you need to improve your 60 foot or short time. The rule of thumb is that every tenth the 60 foot is reduce results in a two tenth reduction in the 1/4 mile elapsed time. ...Published on 11-28-2018 01:44 AM
Automotive magazines are not what they used to be and today survive predominantly on their established relationships with automakers. Many of those automakers are not afraid to abuse those relationships as the magazines are dependent on exclusive content to stay relevant. ...Published on 11-14-2018 08:01 PM
Holy crap. What do you even say to this? A 7-second Mitsubishi Evo 8 from English Racing that runs 7.72 @ 190.04 in the 1/4 mile. This was not some glory pass either as they ran 7-second passes four times. ...Published on 11-13-2018 08:28 PM
You have to give HRE props here for doing something different as their new designs seemed to stagnate. The end result here is not the most aesthetically pleasing wheel as it looks like something out of a Lego Technic kit but it certainly is different and points toward future design methods. ...Published on 11-07-2018 06:13 PM
McLaren kicked dust in Ferrari's face since they launched the MP4-12C back in 2011. It was not even close between the two. Well, it appears the 488 Pista is Ferrari finally fighting back if Autocar's 2018 best driver's car results are to be believed. ...Published on 11-06-2018 03:12 PM
This is an interesting setup and drag racers have messed around with volute injection for a while now. Essentially, you are spraying water/methanol directly into the compressor housing. Prometh says this increases the efficiency of the compressor output. ...Published on 11-05-2018 04:23 PM
Everyone knows the advantages of carbon fiber and various modern composites. Light weight while having very high strength. Metal still rules the engine building world but consider carbon fiber connecting rods for a moment. ...Published on 10-31-2018 03:00 PM
Pure Turbos just continues to expand their offerings with quality and well priced upgrades. Their latest hybrid platform is the Infiniti Q50 and Q60 VR30DDTT motor. This platform is becoming increasingly popular. ...Published on 10-31-2018 10:52 AM
A lot of money is being thrown around by Sentinel Capital Partners and their latest acquisition is the well known Holley Performance Products brand. This brand will be combined with Driven Performance Performance Brands. ...Published on 10-30-2018 03:25 PM
This is admittedly a very cool concept car and something Nissan should really think of building. Especially considering it is using parts they already have available such as the Infiniti 3.0 liter VR30DDTT motor which responds very well to tuning. ...Published on 10-29-2018 06:31 PM
So just how big of a difference does a built VR38DETT with an AMS Alpha 9X turbo make over stock? Well, it is literally night an day. We are talking more than double the stock output and this is why it is so hard to gauge the output of GT-R's as they range from mild to wild to extreme. ...Published on 10-26-2018 10:53 PM
The Nissan GT-R for some time was used as a tuning and acceleration benchmark and a mildly tuned Nissan GT-R is still a fast car today. The BMW F90 M5 is obviously a brand new super sedan and obviously the main change is the addition of all wheel drive. ...Published on 10-21-2018 12:41 AM
Another day, another monster GT-R. This one was built by Top Speed Motorsports and they did a 4.1 liter stroker build for the VR38DETT. The built motor was necessary to accommodate the ETS (Extreme Turbo Systems) Pro1400 turbo setup. ...Published on 10-17-2018 11:11 PM
It is somewhat confusing to keep track of BMW B58 engine variants but the B58C or B58C30O1 to be exact is the Toyota variant of the motor. BMW themselves does not rev the B58 engine past 7000 rpm. ...
Finally got...
Just another top mount build? ACF top mount w/ EFR 7670
