Fuel Additive for TURBO cars

[flowerpowerdave]

Anbody tried/used PowerPour fuel additive for 'charged cars? Its got good write ups on lots of forums, £18 for 500ml which treats 30 ltrs of fuel, much cheaper than racefuels as it adds 4 octane as well as doing other stuff like stopping your engine blowing. Give it a look n post ya comments.

Have I tried/use this product? No but here's my comments.
£18 for 500ml which treats 30 ltrs of fuel - So, a 3/4 tank fill up will go up from ~£45 to ~£63
Do you realy need the benefit of an extra 4 octane, like, are you anywhere near the limit where knock/detonation could start to occur whilst using a premuim pump fuel?

Can you reduce the inlet charge temperature? Larger intercooler, general under bonnet cooling, Water wetter for the coolant system, or even a lower thermostat temperature to reduce block/head temps
Is the spark plug the correct rating for the upgraded engine... Assumimng its an upgraded engine to consider an extra £18 per fuel stop.
Are you running too much ignition advance?
Is the crank case breather still routed into the inkake?

I'm sure fifth gear did a test with 4 different fuel additives and all produced lower power than normal 95 octane fuel.

I'm sure there are better ways to making your engine last longer.

ie what singlespeed said

A good service and running it on premium fuels has a better effect than almost all of these additives, and that's still cheaper every year than wasting money on additives.

Have you actually read the website yourself? I'm guessing not.


Following on from the tests with Jon's Mustang, Power Pour was next tested in the Street Elminator 698ci '56 Chevy of John Hales at the 2002 National Finals at Santa Pod. The car had previously run with a commercially available fuel additive and had run a best of 9.28 / 155mph (with no nitrous used). It was intended to run the nitrous for the first time at this meeting but to start with it was decided to do a normally aspirated shake down pass. The car ran 9.28 / 158mph on that pass, the only thing that had been changed was Power Pour was used instead of the commercially available fuel additive. With 4 degrees of timing taken out (to give 24 degres) the nitrous was turned on for the first time. The car ran flawlessly and recorded an 8.79 / 166mph pass. After the run the engine was compression tested and proved to be in first class condition.

Since its initial development Power Pour has contributed to speed and ET records and Event and National Championship wins within the UK Drag Racing circuit and is now being used in many other disciplines of Motorsport, including 2 stroke motorcycles



When will the twingo perform anywhere near what this product is designed for? Never
Also, all of the reviews are people with proper engines such as a cosworth engine and a 5litre Chevrolet engine


Where does a 1.2 gt fit into any of that?

I've cleaned the thread a little by removing unnecesary posts and edited a couple of posts. Although I have left the comments that have points which do make sense I haven't looked into the product loads. This is because I don't feel the need to as I don't wish to
use the product. I would take into account singlespeeds suggestions for modifications/adjustments. These could give better results and be more cost effective in my opinion.

Here's a website with details, webster-race-engineering.co.uk, oh and by the way RS Tuning in Leeds use this also, instead of singlespeed swallowing a engineering journal and spouting bollox, try reading some of the testimonials from people that know what they are talking about.

Saying Neil who now runs this forum is talking utter bollocks(bollox how you spell it) is retarded, and the website says race engineering are you actually making a race car? As using additives in a road car is a joke and not needed whatsoever.

@flowerpowerdave

Neil is a man who knows what he's talking about.
By all means question ideas and others opinions in discussion, but don't dismiss valid comments offensively as bollocks.

Others on this forum have modded the gt - some with the help of RS tuning - with good success, so why not consider the results from those who have (/have had) good results

Me! Me! Me!

I was the first to get a twingo GT tuned by them and the gains with my mods surprised them for what is a 1.2 with a tiny turbo!

I wouldn't go down additives if I were to buy a GT again I would fit a larger fuel pump, injectors, exhaust, panel filter and front mount intercooler which would see you to the turbos maximum rated BHP of 150, you'll be pushing between 160-170 torques which means the clutch WILL need uprating as my old GT slowly developed severe clutch slip, with more power you will destroy it within a few months.

I would also invest in a good set of coilovers and go back down my ktec brake kit route with braided lines and then fit some standard RS seats.

Then you will have a serious little car which would destroy an RS, the reason I sold for an RS is that it already had the power, improved handling and the dini has a much better interior and looks better so as a standard package its very very good for what it is, now there's more readily available parts to tune an RS I'm glad I got it as the engine note is much better than the GTs and I find I prefer the sound of a screaming N/A more than a lower capacity turbo(3 cylinder engines excluded!)

For what its worth, I actualy use an additive for my car, but only for when I have to fill up with 95RON petrol as I don't fancy writing off 2.5K of engine work due to detonation damage (or pre ignition). Detonation being the fuel air mix starting to burn explosively rather than a clean burn starting from the spark plug which is where a higher RON value helps. Pre ignition, where the mixture ignites from a hot spot before the spark plug fires. Aditives raising the RON value will raise the thresh hold where detonation could occur but won't help reduce hot spots.

A TURBO car is no different to any other engine.... It still burns fuel and, needs to do so efficiently

Hence, questioning the price and need :? Are you close to the detonation point of have cause for concern
Then mentioning about keeping the inlet charge cool and also making sure the hot surfaces that the inlet charge meets aren't going to start the burn too early


Its not exactly an engineering journal, but basic engine dynamics. You didn't give any context when you said discuss, hence thinking it was maybe overkill for a modest spec GT and theres better ways to get reliable power than £18 per pertol refill.

 

[singlespeed]

If you don't mind paying for ongoing additional expence and want a proper aditive that will give a decent increase in performance, look into nitrous injection. A grand will get a top notch instalation with controllers, heaters and pressure switches etc. Then, refills for the liquid nitrous as and when you use it. Being central england, you should be able to find a local place to get refilles of a 5 or 10Kg bottle. It was only the hefty additional costs of shipping the bottles up to the top of Scotland which made it unfeasable for me to get a reliable refill. Make sure you can still get insurance, as many companies won't cover it

The other alternative would be water/meth injection which lowers the inlet charge temperature as the water starts to turn to steam, which inturn expands a hell of a lot pushing the pistons with the power of a train. I've not really looked into this as its not really suited for N/A use which already has a cool inlet charge.

Having looked at the websters page linked above, theres only one mention of a TURBO and that was only a passing mention
