A walkthrough in the garage of the 1600cc Ford Crossflow engine in my TVR Vixen race car plus a little update on the three races I've done so far this season.

Hi, nice to see the engine's eart. Even if i don't understand english a lot 😅.
Vroooooom
Thanks! I’ve been trying to get subtitles to work but not managed to yet 🤷🏻♂️
@@Tomkitek You can turn on RUclips’s auto subtitles
Great video! Love your hoodie ;)
Haha cheers mate
Electric fuel pump? What is the fuel pressure? 3.0-3.5 PSI for 40's. I see you have a regulator, maybe the pressure is just a tad high and the G forces help it push through. Great spec crossflow!
Yeah electric pump. I run just under 3PSI at the regulator. After a lot of discussions, the best theory so far is that the Vixens inlet manifold holds the carbs at a slight angle for clearance and that may be affecting the fuel levels under G force and then overflow? The lotus lot don’t seem to suffer from it but their carbs are nice and level in the engine bay
try a cold air intake to a ram air intake box - you will get a very decent increase in airflow through those restricted chokes.

Yeah I keep toying with the air intake box idea. It’s a little tight in between the trumpets and clutch reservoir so may need to be a custom shape. Poss a winter project
@@Tomkitek remote reservoir clutch cylinder, our reverse mount internally . If you're restricted on chokes get as much air forced in as poss. down those long straights it will give good gains, needs careful monitoring of mixture - good AFR meter is a good investment
Surprised of the free regulations .Noted the information you gave me earlier regarding the Twin 40`s ,but i thought the engine was near enough standard otherwise..Steel crankshaft and rods are not exactly cheap as are modified cylinder heads and camshafts.Then there is the expense of the dry sump system.
Then they restrict you to choke sizes. Doesn`t make sense to me.
Air filters would help with the fire risk i think as well..
Vixen is beautiful...Just how i would have done mine if i had not gone the Imp way instead of my ex WFD 400H..
Have you seen my long standing Piston Heads post on the TVR section WFD 400H TVR Vixen S2
I see what you mean over steel components but the way our series has looked at it is steel doesn’t really give you a power advantage (unless allowed bigger carbs which we’re not) and helps with reliability. From a safety point of view, if someone blows on engine on track, it could potentially be very dangerous for other competitors and certainly expensive!! The same with the dry sump. If someone smashes over a curb it doesn’t rip a sump open with at least 4 litres of oil in it. The dry sump for me ensures the engine gets what it needs and prevents it blowing up as easily 😄
@@Tomkitek Sounds like a sensible approach,but don`t let the MSA catch on as they will make all those regs mandatory ,then make Motorsport even further away from my means.
Looking forward to the Silverstone video..
@@limjamrace different cars within the series have different strengths and weaknesses. I compete in an Alfa GTV. The Alfa crank is bullet proof so no need to replace it but the standard rods on the (comparatively) long stroke are only good for 6000 rpm and, of course, they're all 50 years old. A set of steel rods should last many years (twenty two so far) so make financial sense. The big savings with 70s is that the body ,brakes and suspension must remain all relatively standard and once you've built the car (assuming you don't break it) there are no real season after season development costs
What size are you tyres?
They are 195/55 R15
@@Tomkitek Ahh right. Quite low profile then. My dad is currently using 195/65 R15 on his vixen
@@tomhill2497 Yeah in race tyres it’s hard to get a bigger profile without them going wider. I wanted Yoko tyres but they are struggling with the supply and done have anything. They also at this time only produce the A052 in a 55 profile. Everything else is 50!
