Turns out that RNR also makes the bumpers. Here's the link to ALL their parts: https://www.rnrperformancecars.com/parts/ No...
Hi there. Here in the UK, one can road-register a 355 Challenge 10 years after it was made by simply adding Lights, a horn and a handbrake. I did...
Yes of course. The final power gain is a result of all The incremental modifications. Just the Motec without any other mods would be about 25-30...
Yesterday at Silverstone I saw a 355 CH testing and they had the stock ECU (2.7 Motronic). They had remapped the 2.7 system to bring it closer to...
James - yes, what I meant was that we got about a 50-55 BHP gain from where we started. At the time of the first test, we were at about 325 RWHP,...
Its the smallest MOTEC ECU, the M84. This is sufficient for the V8 of the 355. In other news, we had some bad luck at Silverstone and SPA....
Correction. That should be "Velocity stacks in the airbox". The key is SMOOTH, non-turbulent airflow into the main intake chamber. It is...
Not The heads. Just the intake velocity stacks. Polishing thee gives you the most bank for the buck - about 10 RWBhP. So the tuned Motec...
The dyno was a rolling road without corrections for pressure and temperature. Showed 444 calculated BHP at the crank but the guy said to use a 5%...
The dampers are, as with everything else on a 355 Challenge, quote a saga. This was my first ever 'custom damper build'. I got the bright...
The car as a Racelogic Video-lite system installed so we will take and post video as well, from both Silverstone and SPA... -- Atul
Hi Everybody: It's been a long winter in the UK. I ran the car Feb 14th at Silverstone last month but it rained like crazy and so obviously...
Checked the link and the reasons are fairly lame, IMHO. They say they want to capture the benefits of a Turbo V8 with the "soul of a...
What a disaster. The V12 is the heart and soul of Ferrari. I love my 550 Maranello and am keeping it. If they stop building V12's that can be a...
Hi everybody: about the 'tuning' aspect of the car, well there's always a fair amount one can do but there are increasing compromises with each...
Bob - I'm not completely sure whether ignition advance was added or not. The guys at Advanced Motorsport here at Silverstone are very good with...
Shell premium : 99 Octane here in the UK. -- Atul
If one notices carefully, one will see that the original 'low end torque gains' are now lost and basically the modified GruppeM intake provides...
Now here's the update on the GruppeM intake after the following mods: 1. Hard liner intakes: the intake pipes were custom-made from Aluminum to...
Bob: the test was done under the same exact conditions with in both cases. So its a 'like for like' test. There was air going into the vents (and...
