N2o

Thats the contradiction though Dave Mention N2o, Dastek, cams answer = nope 20 year old engine which will blow up

I reckon as on most good forums it shoud be a place to voice ideas and not to knock without any substance i.e. has anyone used N2o on here i fear not, Dastek, nope apart from one standalone ecu, not yet


When your saying the GTA needs big boost for more power Dave, What level of boost are you talking above the Safe 16psi surely no more the 20 psi that would start to make nos look safe

I don't remember mentioning your engine would blow up, I said your clutch would slip as Nitrous is a power increase that comes in instantly when you choose, it is not a progressive power increase like other mods. If you changed your cams, your not going to gain 50bhp at 2000rpm are you..?


And as for safelty with boost, you can run anything you like as long as everything is done properly and setup correctly. You could run 25psi as long as all the parameters are met..

Hence the main reason for using standalone.

The reason why GTA's have been around for so long and no one has ever got any power out of them in the past, as every one has 'had a go' at guessing what to do with the engine, instead of sitting down, looking at everything logically and seeing where the problems are.

Maybe it was somone else that mentioned the engine blowing up I believe that N2o can be progressive by using a progressive controller 50 bhp with N2o? deppends on the jets 25bhp jets with a progresive controller. Our kid uped the boost on his GTT a couple of weeks ago to 20 psi (With other mods head work, cam, hybrid Turbo) guess what Has soon as it came on boost the uprated clutch let go he's now fitted a padel cluch which if fine for the estimated 200+ bhp, now head gasket probs even with the uprated head gasket, point im making for big boost or big nos where is the uprated clutch for our cars or even maybe head gaskets in unknown territory

As i said it was just a thought with N2o but they would say the same with N2o if it is set up and done correctly you can run whatever jets you like as long as all the perimiters are met

Hence the main reason for using standalone.

Or a dastek

Proof is in the pudding so to speak Really hoping the charge-cooler will reep some good results on Peters car on the rollers, saying that though the benifits will be more on the rollers then on the open road i would have thought


S---- must get on with some work lol

, instead of sitting down, looking at everything logically and seeing where the problems are.

NOT interested in problems , just wish for solutions

Steve, I didnt say your engine would blow up, just that its 20 years old and NOS is quite a savage thing to add, your system may be different, but it tends to be on or off and not a gradual increase.
I said that I guessed the standalone would be around the £1000 mark, but that was including sensors, wiring and set up....and it was only a guesstimate based on Davids initial prediction of the unit being £6-700.
The easiest way to get power gains and go faster is to strip out some of the weight.....you wouldnt believe how light and sprightly my car feels compared to how it started!!! Shaved another 1 1/2 kilos off it today junking the bonnet opening system in favour of pins

Really hoping the charge-cooler will reep some good results on Peters car on the rollers,

I don't know if you saw Pete's last thread, but even with the chargecooler full of water, but not pumping, he saw over 30bhp increase on his last RR run and more torque, and this was including a misfire due to a dodgy HT lead..

point im making for big boost or big nos where is the uprated clutch for our cars or even maybe head gaskets in unknown territory

I put some info on the custom clutch on your Clutch thread, have you not been online for a while?

Headgasket wise, this is mainly down to badly setup afr's, or overheating and distorting it. Its actually very hard to 'blow' a HG through boost pressure, only detonation through running lean, or too advanced ignition.

Renault 5's have/had this problem due to the fact that a carburettored system can't be as closely monitored as an efi system..

I fitted a Nitro’s kit to my 16V Golf GTI. It initially came with a 20BHP jet, once you were happy with the set up you were able then to buy larger jets. I then went for 50BHP jet which made a noticeable difference. When the system was in operation it made the engine feel smother and power was delivered with no noticeable adverse affects at all. The fact you can gain power lower down the Rev range would add credibility to the argument (note I was skeptical of this) you could improve the life of your engine. As opposed to running a large hybrid turbo which requires you to stay at a higher rev range to use the available power. The main drawback to this system however is the fact you have to refill the bottles.

If you go down this route you will like me get bored with filling the damm bottles up and end up selling the complete system for half the price it cost £600. But I did surprise some M3 drivers while it lasted. hahah.

I like to surprise M3 drivers, I do it most days just after I turn off the M 25.

I think a small (say 25bhp shot) of gas would work very well on A GTA. Cars with marginal intercooling respond very well to N2O as it massively cools the inlet charge when it changes from liquid to gas. I've seen 25bhp jets make 35-45 bhp in extra power on turbo cars running alot of boost. With the progressive controllers available now it can be brought in as progressively as you want. In small doses nitrous will actually make your car run better and possibly even extend its life as one of the most damaging things for an engine is high combustion temps, and the N2O will reduce these drastically. The key is making sure its correctly set up with accurate fueling. Yes a standard clutch is probably going to struggle but thats because the engine will make massive torque as soon as the N2O comes in. Stronger clutches are available.

Its late, so maybe im getting this wrong, but a 30bhp(170bhp@the wheels) increase at 1 bar So does that mean previously Peter was only getting 140 BHP at 1bar at the wheels with the chip and hybrid Turbo Surely not

No Pile in the TV's DVD's & all the other bling and just turn the boost up even more to compensate

I did indeed gain about 25-30bhp at the wheels over last time....but last time I had a sticking rear calliper and I had retarded the ignition and not advanced it a touch....the guy also had problems stopping it slipping, but hes now had the rollers grooved. Lee's car showed less than 120bhp at the wheels....the GTA never makes its full potential on a RR due to heat problems, the other thing about RRs is if you compare results on one to results on another they always differ, theres also things like weather, air pressure and what kind of environment the RR is in. I had a long conversation with a tuning guru on the Isle Of Man who said all RR results were nonsense...he said measure things by improvements to your car not by figures on one day at one RR in those specific conditions because you would never replicate them! I didnt totally agree with him, but his ideas are about right.

Like "simonsays74" said in a previous post.
The RR if fine if you take your car to the same one each time. It helps you see how your car is improving, mod by mod.
But because RRs are not calibrated, they are just no good for comparing cars with each other.

Thank feck for that My car doesn't feel like 120 bhp
I will be popping it on the RR before any further mods though ,as the Simons Say it's good to get some idea of how things improve or not .
