Running Without A Catalytic Converter. Smart?

2000 V70 GLT… was wondering if I could just have a muffler shop cut out the converter and weld a piece of straight pipe in place of it? My state dosen’t have any emission laws. Will this effect the drivability of the car? Thanks in advance. Any advice about this subject would be greatly appreciated. The cost of a new converter is approx. $1100, and a piece of straight pipe is around $35 to have put in.

“628” R ECUs and 850s

So, I recently installed a 628 ECU and it works great. It feels like I have a little more boost everywhere, not just for 7 seconds, 30 seconds, or whatever the literature claims. This is in a MY94 850.

High End Turbo Kit, Meet S60 R

Fast Friday Volvo Performance and Tuning

Two weeks ago today we started working with RZ Design on the R32 turbo kit they offer for 2004-2007 R models. With RZ doing the hard work of the install in the first week it left the remainder of the next week for us to complete the tuning. The turbo on this kit is capable of over 500bhp so reining that in to keep the engine safe was priority number one! The engine in stock form is capable of handling approx.

Tune My Ride! ’98 V70 LPT

LPT motors are great when it comes to the low end grunt it takes to get AWD cars moving, but the wastegate setting is critical to get that early boost development that makes these cars so nice off the line. If you haven’t set your wastegate yet I can’t stress how much that will affect driveability.

Water + Methanol = Power?

Fast Friday Volvo Performance and Tuning

Humidified combustion air lowers the peak combustion temperature by hundreds of degrees. This is important as this cooling affects not only the incoming air charge but also any residual pockets of exhaust gas from the previous combustion cycle that can be a trigger for pre-ignition. Adding water/methanol injection to an engine in the proper amount is akin to running higher octane fuel, the increase in ignition timing is so significant that it’s similar to running high octane racing fuel (100+).

3… 2… 1… Ignition!

Fast Friday Volvo Performance and Tuning

The ignition coils used on most cars today haven’t changed all that much in the last 50 years. A simple set of windings that when provided electricity creates a magnetic field that when collapses is amplified and creates enough voltage potential that it can jump a gap between two points. For our purpose with this article that’s as far as we’ll go with the understanding of transformer (ignition coil) fundamentals. Let’s instead focus on the bigger picture as it relates to misfires, specifically those that occur from increase boost and power development.

Review: ARD Green Tune

Another ARD Green Tune Review MVS Volvo Forum user ojdorson writes “It was a real pleasure to deal with Lucky. After a few quick e-mails, I decided to go with his recommendations – ARD Green Tune with M44 conversion. The ECU was shipped very quickly and the installation process is fairly brainless. I lost one of the […]

850 GLT Performance Mods

If the gain in hp from an N/A 850 to a turbo 850 wasn’t that great, then your question would get different answers. But the turbo cars are so much more powerful that the cost/benefit ratio of making an N/A faster just isn’t there. The cost/benefit gets a little better if your N/A is a manual. Note: 1997 GLT models DO have a light pressure turbo, and thus are good for speed mods.

Chip Tune vs. Manual Boost Controller

Fast Friday Volvo Performance and Tuning

I shot an email over to my favorite Volvo speed genius Lucky, of Active Research & Development, formerly of iPD, MVS sponsor. He was happy to give his thoughts on the question Chip or Manual Boost Controller? Now, I know what you’re thinking: he runs a chip tune company! Of course he’ll favor chips! Yes […]

ARD Green Review

Same MPGs, but with more aggressive driving. If you do this, realize that getting on the highway will be a blast, and still faster than it needs to be on the highway, but not as great if you were to go with an 18/19t and [ARD] blue. (no experience with this).
