Just wondered whether 85 hp at the wheels was a reasonable figure. Don't know any engine specs other than its running twin dellorto's & 2250cc
2250cc hp

possible
Old motor with leaky stock heads, a mild cam and restrictive exhaust could/would produce less
A lot more info would be required

Lots of variables there, but it is'nt a lot for that size engine, my 2.0 litre type 1 with 043 VW heads makes 122 at the wheels on a bad day 😂

I am thinking good combo at that size 160hp or more @ the flywheel, what ever that is at the wheels.

My 2007cc showed 100bhp at the wheels on Leons dyno.
Its not just the size, its the combination of parts.
Anyone can build a motor, its knowing what works!

I said good combo, that sounds like average at best. Or is that expectation too high for a t1 engine lol ?DakDak67 wrote:more like 125-135 flywheel, 100-105 rwhpvlad01 wrote:I am thinking good combo at that size 160hp or more @ the flywheel, what ever that is at the wheels.

I would like to know how to get 160hp from my 2276 with idf's, street cam and heads. I'm all ears ...

My 2332 with VW non welded heads and 44x38 valves made 140+ at the wheels, so you're not being unrealistic Vlad

And since we're on the street Chris, that was under 10:1 comp and totally streetable, 48 IDFs or Dells will do it.

we'd better step up from 8.5:1 and 44 idf's next build then Matt. That said, your attention to detail and tuning is pretty rare , I'll still safely say the average built big engine has no where near 140 on the wheels. Anyway, I would be happy with another 25 HP !!matberry wrote:And since we're on the street Chris, that was under 10:1 comp and totally streetable, 48 IDFs or Dells will do it.

Do you have the dyno chart at all ?
Don't fall into the trap of only comparing peak HP numbers.👍

liters = potential power x 100 for real R&D'd NA engines.
it applies to pretty much all engines.
more obtainable figures for general performance builds is about 75hp per L
bog stock engines these days make 60-70hp per L

I'm looking forward to the Dyno day at Leon's. There will be several 2.2+ litre street engines running , I'll post results for the OP to compare .

150- 200hp 2270cc is not uncommon for a good combo for t4 engines which makes power everywhere in the rev range.

And particularly if you live in the US. All quoted dub engine hp outputs there are 50% greater. Must be better air in the northern hemisphere 😂

I know a lot of people argue the metric hp is way different to regular hp.
its like 2.4% different.
2.4% is double!!! 😂

I haven't got dyno sheet, but from memory it was about 4700rpm. I know there are a lot of variables that come into it, just didn't think 85 hp was that good for a 2250cc engine. Having said that, I'm new to this big bore/stroker stuff!

If it's making its power at that low rpm, it's probably a very mild combination. A friends 2l kombi motor on webers, mild cam etc was just under 80hp at the wheels and is a strong motor for a comparison point.

Could be a nice torquey streeter that is non stressed

Makes sense. Back to fundamentals the power is equal to torque x rotational speed.
So you could have a HUGE torque (like a typical diesel) come about at a nice and low RPM, but because of the low revs it will equate to a small HP.

yes, that means it can haul weight without slowing down much.bajachris88 wrote:Makes sense. Back to fundamentals the power is equal to torque x rotational speed.

but actual power is what give you acceleration. but more importantly is how the power curve looks, if its broad it will give the best performance, if its peaky, then is useless most of the time until it peaks like ricer cars do.

yes, thats cos its boarder at the bottom end and fall off quicker at the top end compared to dp gearing is also part of the equation.
I have not see direct comparison between the 2, but I bet the sp has more torque thus more hp available at the low revs than dp does.
if you have 1000 torques and 0rpm, there is 0 hp and it does not move.
good way to look at it if everything else is equal and disregarding the little factors like gear ratios and crap like that
double the hp = double the acceleration
double the rpm but same hp(halving the torque to equal)= same as before
double the torque same hp(halving the rpm to equal)= same as before
but we have torque curve and thus power curves, so in reality acceleration and top speed depend on the curve and gear ratios and other factors like weight etc..

85whp @ 4700rpm os ok, what are the Torque figures? Do you like how it drives, does it put a smile on your face, if you answerred yes, what difference does the amount of HP make?
This whole thread is based on speculative information, no engine combination info and no dyno sheet.
What exactly is a 2250cc, did you buy the engine with the seller telling you the information without substantiated evidence?
Two different engine builders will build two different engines even if the combination of parts are the same and theoretical engine conbinations and Hp calculations are only a guideline of the outcome eg. mumbo jumbo.
More information please, even just for curiosity.

It makes sense to me now why T4 motors have good torque ... it is because they flow just the same as a single port T1 😵

85 good, you don't really get to rev past 5000rpm on the streets to often, just get out on the road and enjoy it .

a good t4 combo will make power and torque everywhere, much more than a t1 can.
