Hey Mats, I was not making a case for supercharging vs turbocharging, I am making a case for forced induction vs normally aspirated. The limit of 1.7 liters for turbo cars makes my point exactly. Mats, we all know you are a forced induction guy. Don't even try to say you are going to build a NA moto...

It's no contest, the supercharged engine will kill the n/a engine. Here is an example: https://www.youtube.com/watch?v=0MFKMYN6xZw The supercharged car here is a 3.0 with a 2.5 crank giving 2.7 liters and is a relatively low budget affair. It easily out accelerates everything else on the track inclu...

I firmly believe that more than 350whp is going to result in a very short transaxle life. What's the most reliable way to get 350-400hp? It's forced induction, either supercharger or turbocharger. Reaching that level of power with a normally aspirated Alfa V6 is very difficult. It's no secret I favo...

The THS rods are great, but we could only sell 1-2 sets a year and that's with very little mark up. Add in the 20 email questions we had to answer for each sale and it just wasn't economically justifiable to keep them in stock. They are great rods. Those rods+forged pistons = nearly indestructible b...

I have always had success with Total seal rings. Gapless for the stock cast pistons, with gaps for forgies.

We use the backseat almost every day.

It is huge compared to the original, but it's still pretty small for a modern car. It's smaller than a Mini, yet has more space in the backseat, even more than the mini-clubman.

It's a little small for a family car, but not bad. An Abarth is our primary use vehicle at the moment. It's fine for any trip with 2 people. With three or four it gets a little tight, but not bad. I would like to see a slightly larger version with a 1.6 or 1.8 liter engine, say in the style of a ret...

I worked on a new Fiat 500 Abarth. A few minor mods and we got it up to 192whp. All the details are here: http://forum.abarthspeed.com/forum/performance-tuning-modifications/fiat-500-abarth_aa/688-abarthspeed-dyno-day-1-results I am pretty impressed with this car. It's a lot of fun, and easy to get ...

Nice pictures! The red Callaway with the Maratona kit is my customer's. It's in my shop getting some performance upgrades right now. Forged pistons, modern engine management, and other basic stuff.

I have been doing a little work with the Fiat 500 Abarth, basically more boost, intake, blow off valve and water injection. The guys at abarthspeed made a video on their front page. If you like these cars it's worth check out. http://www.abarthspeed.com The video starts pretty much right away.

They are essentially worthless. Even the junkyards don't bother to take them off before they crush the cars. A good M90 fetches $150usd tops. Worn out units are about $50 or less. Rebuilding them is easy and involves a "snout rebuilt" kit and new bearings, all of which can be had for aroun...

At 5.3 litres and 4 valves per cylinder, I'd guess that both of those Aston Martin superchargers were M62. I think Aston Martin did it like that just because they could. Who had churned out a twin supercharged engine before they did? And besides, it looks awesome. Hate to have to work on it though,...

Zamani, I don't have a good answer for you about the cams' effect on effective compression. I understand the theory that says hot cams will in effect lower the effective compression ratio, however in practical terms, I am not so sure. I don't know all of Eaton's casting numbers, but a 45ci in too sm...

Wow, a supercharged 3.2! Yes, as predicted, I will say almost any decent supercharger will allow the 3.2 to make enough power to break the transaxle. At the bottom end of the scale, I would use a salvage yard Eaton M90. In a perfect world, money no object a Sprintex S335 or a TVS 1650. For crazy pow...
