would it be possible to get any where near 200bhp with that set up? but obviously not standard internals, tim Edited by: Tim_mk2
No.. A decent standard 1800 will make 155BHP, so with flowing work, mild cams & correctly set up carbs maybe 175BHP.. Any more requires a capacity increase..
rite ok, the engine in question is already modded and has 177bhp, would a 2l bottom end, or bore be the next option? tim some basic info on the engine: Edited by: Tim_mk2
Would need to be a 2L block IMO....An 1800 making circa 170BHP is going to be a very peaky engine..especially with max power all the way up at 7000rpm.. A capacity increase will give it some much needed torque lower down & make a bit more BHP... Any RR figures can also be taken with a pinch of salt IMO....
RR figures give you a ball park figure i supose, so next would be a 2l bottom end for some torque?! i recon as it is its going to be fairly rapid, compared to a 1,8 driver with a weber twinchoke that is! tim
the insurance would drive to your house and physically kick you in the balls, and take your house as a first payment!
1.9 converted KR motor running ABF injection and DTA finally made 180bhp last week Stealth. it lives in a passat so is still underpowered... sadly. revs well.
200bhp is well within reach, for a good 16v engine 140bhp/Litre is full race spec so for a 1.8 thats 250ish. 1.8 with steel rods, forged pistons, L+B bottom end, fully worked head, some prity wild cams. 200 should be obtainable. However you may find the std timing setup will hold it back so mapable ignition system or even a fully mapable ECU and throttle boddies would be advantageous.
A 1.8 in that spec would drive like CRAP A stock 2.0 bottom end would be quicker in nearly every situation.
I thought they were about 135ish from the factory? So what work would be needed to get to 155ish? I'm curious... Mine's an 1800 16v lump in my Mk1, totally stock apart from a supersprint manifold and exhaust system...
VW quoted the KR at 139BHP @ the flywheel... Vince @ Stealth reckons most standard Valvers give 140-145 atfw on his RR..given that VW were always a tad conservative with claimed figures.. Add to this, a decent exhaust system with 4 branch, K&N or similar filter...plus the fabled WUR mod as required & it is quite feasible to squeeze 10-15BHP more..
Yep, After a set up of timing and the warm up regulator mod which increases fuelling under load, most standardish 1800 16vs put out 150-155bhp @ Stealth, whether it's an accurate power output or not is always open to question of course
Who knows... Given a decent setup, most standard cars tend to give a few BHP more @ Stealth than the quoted VW figures. This holds true for 8v/16v & VR6 models... 10BHP from basic air flter/exhaust system mods & proper fuelling/timing seems about right to me
I know figures can vary from day to day but mine have always been pretty consistent over the years @ Stealth Having seen vids of other rolling road operators ragging f*ck out of cars on RR days, I'm more than happy to go to Vince with mine, he never gives the cars too hard a time
Full race spec KR wouldn't drive like crap atall, for the job it is built for it would be a realy clean reving screamer of an engine. However for a road/occasional track car yes a 2l could would produce similar power at lower revs with more torque ane be far more driveable. In lighter cars like Mk1's lots of people prefer the shorter stroke 1800 engines over the 2l because of the revy characteristics. Each to their own.
The car in question is a road car though.. Sure, a race spec KR will rev its nads off when it eventually comes on cam...great on track...poo on the road!! For a road going car, 200BHP is only realistic from a 2L with all the works.. A standard 2L block with a lightened flywheel, such as my own, has no trouble revving to 7.5K revs.. Edited by: chrismc
