How safe is a VTS standard crank? How much power and revs will it be safe at?
VTS crank
-
#1
-
#2I have and will only take my VTS up to 5,500 MAX! Never hit near 6,500 or 7 else u can say bye bye VTS!
-
#3bottom ends are very strong on tu engines
was tested upto a high amount of rpm cant rember what now though -
#4still i wouldnt trash ya car every where!
-
#5Bic who is now on here from time to time is running a standard crank on his maxi which iirc is around 208bhp @ 8000 or 9000rpm.. He has had no probs as far as i'm aware.. You just wont break a TU bottom end on a standard powered car, the car will fall to bits usually before the engine gives up..
-
#6Thats not true, have faith in TU engines, citroen have been in the game of making cars longer than most companies, trust me they are really good engines. the only thing that makes people think citroens are unreliable is the fact that sensors play up from time to time.. personally my 1.4 which has the same bottom end as the VTS has been ragged everyday since i have known it from 60k and its now on just over 105k and not one thing has gone wrong with the engine, coilpack went and ICV played up thats it..I rev mine right out to 6200rpm everyday on the way to work and back and it just laps it up, i dont know why there are so many so called "enthusiasts" that put there choice of car down, if you think it wont take it get another car..Quote:I have and will only take my VTS up to 5,500 MAX!

#7so wait wait . . Ur telling me that i CAN trash my vts then??
-
#8It not the fact that i wont give the old girl some its just i have blown a corsa 1.4 up and a fiesta ZS up! so u can see why i am worryed.
-
#9yes, aslong as you perform regular oil changes and general maintanence..

#12Ok then i will give my beast abit more on the way to work tomorrow! I am having a cambelt and oil change end of the month and maybe a head gasket change ( just on the safe side ) Thanks for the info here have some rep!
-

#16If he comes on here tomorrow with a "i crashed my car" thread, i'm not responsible..
-
#17LOL touch wood i wont
-
#20Thanx steve and thank you all. i now know more about my engine thanks to you nice peeps
-
#22you'd usually only consider a steel crank if the car is going to spend a lot of time at high revs. Endurance racers do this for reliability.. but also if the car if going to be revved outside of its intended design.
If you look at the peak power figure on the VTS it is below the redline so you shouldn't really be bouncing it off the limiter at all -
#23Hmmm well since where on about engines here could some1 tell me how to keep my VTS cool! as at the moment when i am stuck in traffic and its a hot day my car over heats! Any way or a part i can buy to keep her cooler?
-
#24Agree with what kam just said, but a standard bottom end will take track abuse etc aslong as the cars not too modified, but then bics car seems to be ok.
Just warm her up and regular oil changes with decent oil it will be sound..
-
#26Added to my list for service end o month! thats if my car hasnt totaly overheated by then!
-
#27thats what i need, a new thermostat.. Hard to fit??
-
#28Quote:Hmmm well since where on about engines here could some1 tell me how to keep my VTS cool! as at the moment when i am stuck in traffic and its a hot day my car over heats!
when u say over heats do u mean the temp is high or it overheats and chucks the coolant out? -
#29lol this is becoming funny now where all helping each other out with different things! wanna start our own garage any1 lol
-
#30I mean the other day i had to stop at KFC ( Lovely ) cuz the red dot lighted up on the temp ( left side of gages ) any ideas?
-
#32thats not right at all, u can try a coolant and thermostat change but it could be headgaskette, blacked rad or shagged water pump, have u inspected ur coolant?
-
#33so how much is this gonna cost me then! on my list is :
1. New Cambelt
2. New Coolent
3. New Headgasket ( safty )
4. New Thermostat
Hopefully all done at the same time! -
#34I topped up the rad other day and it seemed alot better then befor ( when it over heated ). I will have another look at it tomoz! tbh i cant see the feckin levels cuz its hard to see where the lines are on them.
EDIT : i checked the oil and theres not water in there so that means the headgasket is ok right?? -
#36it migth not be the headgasket so dont jump to conclusions, if it is the headgasket u can do the job urself using the guide i wrote and it should only cost u £100 in parts if u get citroen to do it expect to pay £400
-
#37not nesesarraly mine was letting combustion gas (air) into the coolant system, might jsut have an air lock, get it bleed out properlyQuote:I topped up the rad other day and it seemed alot better then befor ( when it over heated ).

#38do a compression test to check the headgasket. Testing kits are only £12-15
-
#39If you have no oil in your water or water in your oil and no mayonaise stuff under the oil filler cap your headgasket is ok...
Also if your headgasket is screwed it could end up only running on 3 cylinders etc and you will notice that alot! -

your forgeting the fact that combustion gasses can be getitign in the coolant, so jsut cos he might not have the symptoms u described dont mean his headgasket is fine. a compression test or a chemical tester will check and see if combuston gasses are getting in the coolant -
#41i think the saxo engine are tested upto 10-15k rpm????????
-
#42Ok i will check these tomorrow. right now i think bed is a good idea! night all speak to ya tomorrow.
-
#43cant be arsed to read it all.
i read TUs were tested at up to 15k on standard internals. the normal crank has been used by many revving highly, as stated bic, and many other big bhp tbd engines. the standard crank is quite strong but also balanced well for that matter
