Don't know what you're on about

I haven't really slept in a few days, so I'm feeling the effects now. Can't think, let alone type right!!

seems like we need an airfield day to test this theory then

Already have m8 its called the A174 , 7 miles of Gatso free dual carriageway ,
Revo cars were done in the first mile .
@120- 130 mph bye bye Revo and TT225

At stealth in november (SE RR Day) Skoda octavia RS same mods as me essentially had 249bhp and there is a Revo Golf also with 249bhp from the k03s (Golf on here) But thats where my 'from 230-250' came from.

As mike from Jabba said its the cooling that kills the power of the K03s (or lack of) as heat builds up V.Quickly. But i have a fairly large fmic so it shouldnt be a problem and also race cat/downpipe which he said was another restriction.

If i get between 230 & 240bhp i will be a happy bunny for what i spent on the turbo and intake (£200) so a 10/20+bhp increase, exra torque, more drivability i.e sustained bost etc.. Its a bargain as an induction kit can cost this and not increase.

Anyway fingers crossed, should all be sorted for first week of feb and hopefully have some good reports/figures etc.

Hope the cars does good shock, i am sure you will let us know how it does.

depends if it produces good figures, if its low ill hide my head in shame!

same back at ya mate with yer e05

 

[Madmile]

I want good power, but if the car does not do so well i will post up anyway, someones gotta give it a go. And then scn members will be able to make imformed choices.

 

[Copra]

Is my car as fast as a Jabba chipped car? Probably not, do I care? NO! The car performs how I'd like it to. One of the reasons I chose Revo was the stelth option, the other was convenience as Jabba is miles away

thats what i think too.
mines revo'd and its more than fast enough for ME
Mine prob ends up being out done by a CTR at 130mph too (ive never raced one) but to be honest, id rather have a blast down some lanes than down a dual carrage way..
'fun aint in a straight line'
i like that quote!
most of my driving at the mo is 2+from work. its all country lanes, i need mid range, which is what my car is great at. thats all that matters to me

[Shock_Xe]

I chose revo for the stealth, closeness and good mid range pull, as most of my driving is here and very rarely top end (usually too far infront by then )

However I am about to switch to Jabba after selling my Revo ECU as Revo's one current disadvantage is that it doesnt allow the program to make best use of modifications such as i have done to which end the stealth and distance to dealer becomes 'tolerable' as more power is preferable. Hopefully wil see more 'Top End' with the K03s and a remap to suit.

I just wish i could doit now as cash is waiting bloody booking! wots that about

If this was the case then our ignition would never be retarded, which it is.

Higher Octane allows you to run more ignition advance without detonation. If your ignition is already advanced and not being retarded then the higher octane will result in less power. Why? See this link:

http://www.merkurencyclopedia.com/Fuel/fuelchem.html

Specifically paragraph 1 of the Engineering Data section, which says:

"Higher octane has a higher threshold of energy level required to start combustion, therefore there is less chance of detonation. If a engine is not detonating, higher octane WILL MAKE LESS POWER. Use the lowest octane without detonation."

So in other words, higher octane makes your fuel more difficult to ignite. The more difficult it is to ignite the fuel the less chance of detonation there is, and so the more advance you can have. But once you have advanced as far as you can then the fact that its more difficult to ignite means that it produces less power.

So, if you have a car that never detonates (And therefore retards the ignition) on 95ron fuel, then 98ron would actually make it run slower!

However all our cars DO retard the ignition (Indicating detonation) and therefore would benefit from higher octane fuel.

Ben,

Regarding "If a engine is not detonating, higher octane WILL MAKE LESS POWER"

In theory this is corrrect, but although knock resistance between the fuels is quite different, in practice the calorific values between most pump fuels i.e 95ron and say optimax 98.5ron (on a good day) are very similar. If the the calorific values are the same, energy release is the same and the burn rate is the same.

Therefore, for a car with fixed spark timing running with no det on 95ron fuel, adding optimax will make no difference to performance. If however you were comparing something like 95ron fuel with 110ron aviation fuel then the theory may be proven as there would be a greater calorific value difference.

Regarding knock,

Reading your post again I think we are both agree that our engines do reach and exceed the knock limit on ocasions, but most of the time they run just under the limit by using the ECU adaptive learning.

Cheers
Chris

there software is the smoothest and more powerfull around
with better gains that a generic chip, but this just is not the case!

if you want to stay at a chiped stage then revo is very easy, but generic is the way forward with a remap to suit your car and mods, having it taylored to your needs with smooth initial power delivery sustainable boost and high top speeds!

What is the bit you are having probs with?

Which IMO at 200bhp level isn't cutting the mustard .

Choice REVO EO5 OR Jabba mapped EO5

I know which way i will be going .

Look at the stats logically REVO claim 212 bhp compared to my AMD 203 bhp ,
Which is the faster car ?????

REVO not a sniff .
AMD equipped ibiza everyday of the week @ a loss of 9 bhp in comparison .
So what makes you think REVO will do any better than anyone else with EO5.

You pays your money etc etc as some of you are finding out unfortunately.

How many different REVO cars have been compared?
My lessed power Oettinger passed more powerful cars - Go figure. Not got an explanation fo rit, but it happened.

A Lot?

Not many round my way...
120/130.... thats 3rd gear is'nt it

I doubt you'll reach these speeds on an airfield though, not even a long airfield like Brunty. (OK Bill, we know you will )

I'm not anti Revo or any other make of chip, but for me the biggest problem with a generic map is that you don't get the full benefit of any additional mods you make. The generic map assumes an otherwise standard car... so if you add a bigger exhaust, an induction kit, change the intercooler or anything else then you wont get the full benefit with a generic map.

Custom maps such as those done by Jabbasport can make full use of any extra mods you have done. I believe that if a Jabba chip customer makes any further mods then Jabba will tweak their map to take advantage of the new mod for £95... which is pretty good (Not 100% sure though).

Also, everyone sees the Stealth ability of the Revos as such a great feature, but why? I keep hearing concerns about warantees etc, but in reality I have taken my car to 4 different Seat dealerships and they have soon realised that its chipped yet none of them ever queried the warantee work they were doing.

Under warantee laws the car manufacturers can't invalidate the whole cars warantee. They can however invalidate a warantee repair if the cause of the fault could be directly linked to the modification... for example, if you get your car chipped and 2 months later your window wipers stop working then they still have to honour the warantee on the wipers, but if yu engine or turbo blows up then they can refuse to fix that on the grounds that the chip put the engine under more stress.

So in short, my car is chipped and it doesn't have a stealth mod, yet I've never needed one.

Ben

The people who wrote that article are the experts, not me.... but my guess is that when you increase the Octane rating without advancing the ignition then the point of (full) combustion happens later in the cycle (ie. the higher the octane rating the longer it takes from the point of ignition to full combustion). There is an optimal point for the combustion to occur and if it happens slightly later than this point then you are wasting some of the power. So I don't think its just about the energy values of the fuel, its also about the timing at which the combustion occurs.

At this point I'm starting to get out of my depth... maybe Max_Torque can give a more detailed answer?

All I know is that that article states clearly that if you are not suffering from detonation then higher Octane will result in less power.

Cheers
Ben

Try taking it to my local stealer!!

I was talking to one of the salesmen, who informed me that if I chip my car (I said a mate of mine had ), then I invalidate my whole warranty!
It dosen't matter what you (or they) say about whether or not warranty should stand, I can't be assed with the hasstle of arguing with them, full stop.
A couple of days ago, the dealer sent someone to get my car, and I was glad of being able to turn off Revo. 1) So they didn't start asking questions and 2) I'd rather they drove it as standard, and not come to floor it on the road and find themselves in the back of the car in front!!

 

[Madmile]

I told Pennmans my car was chipped and they still fix everything anyway. Diff dealers must have diff attitudes.
