It depends. Like, yes a 2 litre will have more power, but will it accelerate as fast as a 1.8 due to the longer stroke?Quote:

You may also find that driving aggressive increases your entry speed, but due to not having a hell of a lot of HP, you wash off speed coming out. So you end up back at square one because the engine can't pull out of the load you are inflicting on it mid corner/exit.
I figured the really slow times were dirty laps.
You really are doing well Pete, and I commend you on getting out there and having a go! :)
Yeah I figure this motor just isn't a revver. There's plenty of torque but it just won't pull much beyond 5500. The same head and cam on the 1800 was letting it spin to 8500. The bottom end is tight with good compression in all 4 and it doesn't use oil so I think that's just the nature of the beast.
I've got a better head and cam here but I don't think that's the issue.
The bottom end cost me $50 and has been an interesting experiment, I'll keep running it in this trim to practise with and try to make some progress on the track car.

well Pete come holidays, looks like I'll have to come round and give you a hand putting the race car together! LD
hi peter, what choke size are you running in the delorto's? In the long long ago, I used to drive petrol cars, 1960's alfas actually. The 2L twin cam with twin side draught webers was more torquey that the 1.8L which was 'sweeter' and revved very nicely. They both had the same jetting and same chokes. To get a similar rev range from the 2L, a larger choke could be used to help top end breathing. This could affect midrange driveability, and definitely required rejetting which is a nuisance.
I'm wondering about choke and carby sizing myself.
I never ran the carbs on the 1800, that was running K-Jet.
Currently they're 32mm chokes in 40mm Dells.
I've just picked up a set of 34mm chokes to try out and see if the top end improves.
According to my Dellorto tuning book a 2.0 could use anything up to 38 mm chokes in 45s.
Biggest chokes I can put in the 40s are 36mm but the body might be too restrictive to let that work.
Pete
It also depends on what your head is capable of flowing. If your head doesn't flow, it won't make much difference. Definitely worth a try though. :)Quote:

I need to do some running about to get it checked out and change the cam followers over to a better style without the shims on top.
Pete
or twin 45's..... You're probably better off either sticking with what you have or shrinking the motor to suit the carbs. A 1.8L would probably benefit from 34mm chokes too, that is if you want a screamer
