wow whats your 0-100 kmh time?
Ive never timed it but maybe 4.5 seconds.
Its 2022, can we get a new vid! Love the car
I’m looking to build one like this off an 8v engine. What would it cost to get this done in a shop?
Do you still own the alpha romeo 33
Yes
@@tarakai2 is it still in good shape
When I stripped out all the electronics from mine, I was amazed that it had worked at all. I found so many dodgy wires, loose connections, poor crimps... That error is likely just a crappy connection somewhere.
Hi, this build is nuts. im building a 33 and i want ot ask about the internals of the engine ¿are they stock?¿how good the engine stand the power?
well.... you need forged pistons and you need to lower the static compression from factory standard 9.8 or 10"1 ? down to something lower like 9.3 . This depends on what fuel /boost you want. 98 octane or E90 Ethanol. In twin charged state you could stay with current compression and ethanol fuel as long as the tune is good. Water injection helps alot. The crank is standard. I had some near side inlet porting done to both heads for better flow. What's imperative is that you precisely measure your head volume from one head to the next to ensure that each head produces the same burn characteristics otherwise mismatched air fuel ratios under load conditions will happen and one head will run lean and then BOOM detonation. The gearbox has a 20mm? aluminium sump plate instead of the standard pressed steel sump. The clutch is an aftermarket VW 8" single disc Kennedy stage 3 drag clutch. The engine will produce probably 420 HP at 7000 but whats the point... the tyres break free at 4000. The secret is probably the pulse effect after the exhaust ports which is what the PD supercharger provides and probably the way I welded up the turbo manifold. I am proud of the fact that I can keep the original throttle bodies and keep the responsiveness they provide. I also have a turbine backpressure to inlet ratio of 1.2:1 so the COMBINATION of the supercharger and the turbine housing size work very well.
I forgot to also reply to your statement that no, there isn’t a throttle body in front of the supercharger. I have kept the original throttle bodies (1 per cylinder ) and the original 16v manifold for the responsiveness. So ... like this.. air filter...compressor....a/w intercooler... waterinjection and into supercharger...blow off valve....second a/w intercooler ....second water injection...original manifold....original throttle bodies per cylinder into engine. Phew !
What head studs and gasket are you using and where did you get them from? Amazing build
standard head studs and factory gasket. I just make sure that the heads are immaculate (clean) to allow the gasket to do its job properly. No o-ringing etc. There is no point in going for more power when I spin tyres at 4000 rpm.
You Sir you just won mi heart would love to go in a pub or better jet in a garage and talk all day & night... wish i could make mine one day Supercharged at least... Cheers mate e Viva :)
Thank you Jimmy. Yes a lot of time fabricating small bits and pieces but a great journey in doing do. There is nothing like doing it yourself and when it all comes together after doing so much reading,researching and testing then there is great satisfaction. Cheers Phil
nice work! i have turbocharged 1.6 boxer with 87 pistons and 67,2 mm stroke crankshaft, 8 valves(from my calculations, the comp ratio is around 7:1 now) , its porducing 180hp and 220 Nm at 0.9 bar I am using FMIC too now I am trying to change the engine for 1.7 using standard pistons and 72mm stroke crankshaft, and use the stock compresiion ratio of 9.5 :1(but I think its more like 9:1 from the factory) is this possible with 1 bar of boost(maybe 1.2) and runnning 100 octane fuel? what would be the power? i would go for higher comp ratio for more torque down low, its a daily driver
Alfa boxer power
Yeah was a bit lame. I have since replaced the knockoff td06 with a blouch 1.5 xtr which spools a good 800 rpm earlier. I hav to weld some chassis cracks up and then get a new vid up.
Thanks for your comment. Normally for supercharged applications there is a throttle body before the supercharger. However I wanted to maintain the sharp responsiveness of individual throttle bodies . A turbo flowing air into a positive displacement supercharger is not restricted by the supercharger but there is restriction if a supercharger flows into a turbo. The key to my setup is having a large bypass or blow off valve after both the s/c and turbo so that all boost is dumped whenever it's not required. I have just copied the lancia S4 set up but I am dumping boost to atmosphere rather than feeding it back in pre s/c. You also have to have a soft (1 or 2 psi) spring in the blow off valve to allow boost to escape in part throttle (cruise) conditions.
Well done. Love it. Only thing that didn't make sence was air path from turbo to super charger. On an eaton fitted to say a BMW Mini Cooper S R53 you have a throttle body before the supercharger inlet. So in your cars case it should be turbo outlet to water to air. Through water to air into throttle body before the super charger. Super charger outlet to water to air then in to the air manifold.
nice project.. but come on.. thats a STD 1300cc lounch !!! show us some horsepower
nice job,great sound.....
Awesome crazy build !! >:D But man you can't end it like that... Show us some real driving shots !! :(
