i have a mk1 fiat punto sporting, i had it rolling roaded today and i was pushin 93 bhp. is that good for a punto sporting mk1 1.2 let me know what you think and also any1 got any comments on how to add that extra 8 bhp ?? im thinkin powerboost valve and possible a new manifold ???? look fwd to your comments

nice thats 7bhp more than standard which is 86bhp, try a full exhaust system gsr induction kit and a remap thats sure to add that?

thx for the comment but i shud of saidin the last message ihave a fullexhaust system well up to the cat and i have a bmc direct air induction kit.
so just the chip lol but i think ill go for the power boost valve cz iv been told that a chip basically irons out the creases of your power by plating with the fule out put but thatis also what a properly tuned power boost valve would d
o. :slayer: so ill go for the cheaper option first lol any other suggestions tho or if you want to correct me i would appreciate it

power boost valves do nothing at all. dont waste your money.

the only thing that they do, is improve the throttle response on some cars, NOT add power... and puntos have responsive enough throttles for anyone.

if you want more power....

what sort of exhaust is it? also whats the induction setup like.
if the insides arent completely smooth, that drags power, plus if the backpressure of the exhaust is important for keeping power and torque.

you can get a remap for £200, that will easily see another 8bhp with the mods you have...

you could cam it... ex. and in. manifold, a de-cat will give around 3bhp, up the fuel pressure regulator and fuel pump and then re-map it, bigger injectors as well if you want.

I want to rolling road mine... how much was yours?


You can advance the cams, make it like a vtec. ONLY very slightly when doing the cam belt.

aLSO run the car on a high octane fuel (bp101) and put octane boost in it. this alone will give at LEAST 6,7 bhp

first of all, uprated injectors and fuel pressure is totally unnecessary for small mods... i know of the same engine running 120bhp N/A no bother....

a RR costs about £30 where i live.

the sporting engine is very sensitive to being a notch out on timing, it can run like crap. further more, it only has a single timing pulley (the other cam is chain driven off the first one) so if you advance or retard, both will do the same thing, so there is no benefit.

also, a small N/A engine, unless it has adaptive spark advance, there is no benefit from running high-octane fuel. on turbo cars, yes, on the fiat 1.2 16, no.

sorry about the rant

mine was £28 including the vat iwas thinking about the cams but that is mega money lol well i herd that a power boost valve will get ride of flat spots and i do have a couple at about 3000 rpm. yh the remap might be a good idea but i cant find it cheaper that 299 anywhere i neva herd of puting high octin petrol and octain booster in wouldnt i run too purelike rocket fule lol ??? thnx for all the suggestions ppl keep them cuming

probably the best place anywhere to have it done.

I hear a lot of things too, but that is all about hearing.

There is no proof that is accepted in scientific terms that a power boost valve works on engines controlled by a modern factory ECU. If it were all that easy, good and cheap, why doesn't everyobody have it?

go to VP racing fuels and there is a motorsport fuel with 109 octane rating, it does make a differance.

The fuel pump and injectors you will benifit from if the car is mapped after. Simple things like putting resistors between temp. sensor and ecu will evan work! but in the long run the engine will havemorewear...

Evan cleaning exhaust ports makes a differance, skimming the head and using an up rated thinner gasket will help..


How many miles ur sporting done?

you forget to say, that mods ONLY work well if they complemement each other.

for example, if you filled up with 109ron race fuel, then had the car remapped to give the corresponding ignition advance (all the higher rating does is to give you more room to play with advance, which will give you more power higher up the rev range) then you would get more power, probably not too much more.
and then, as soon as you switched back from 109ron to 97/95ron, the car would start pinking, and your engine would very soon become a dead engine :bang:
this applies primarily to boosted engines, but it also applies to N/A engines, although the power gains/damage done wont be as high, AFAIK.

now if you just whack some race fuel into your almost standard punto, all it will do is cost you a lot of money for no benefit... maybe even less power.

now the other thing: of course uprating the fuel delivery will help with power gains... but please keep it in context; a small power hike DOES NOT NEED IT. a remap on the OP's car, as it is, would not gain any power at all by uprating the delivery... the ECU controls the time that the injectors are open for. a remap would increase the time that they are open for. Now its only necessary to increase injector size and fuel pressure, if the power of the car reqires it. the standard setup is well good enough for 120bhp in the mk2 punto (the mk1 should be the same)... hang on, ive already said this...

oh, and if you believe that resistors actually work.... LOL. just LOL.

cleaning up inlet and outlet ports is a pretty good idea, but not worth the hassle (or money if you cant do it yourself)- if you want to do this, wait untill you need to take the head or manifolds off for something else

resistors do work.

if you class overfuelling and borewash as working then yes, they work brilliantly.

without the extra air, there is no point in giving the engine extra fuel as it cant use it.

how do u no how much your exact BHP is???

do u go on a dyno thing or is there another way?

how much does it cost to check it?

thanks

you can get a Rolling Road printout for about £30.

what this does is put your car on a set of calibrated rollers, and accelerate the car. the computer calculates the resistances overcame, etc, and converts the figures it gets into a graph that shows where the power and torque is in the rev range, and how much you have.

NOTE: NEVER trust a RR printout as gospel truth, they can be way out sometimes, depending on many different things.
the best thing RR printouts are good for, is comparing the difference between before-and-after engine modifications

you will only suffer bore wash if you put a crazily high resistor in there.

drag cars are almost on hydraulic lock from the amount of fuel the put in each cylinder

do you even know what borewash is?

they put that amount of fuel in and use it all

iv got a sporting mk1 16v and im wondering what would be the best parts 2 buy for my punto to make it a bit quicker iv got a filter and back box but i want it a little quicker as my g/f just bought a saxo vtr mk1 and i dont wonna be put to shame if u get me any comments are apretiated thanks
