so about an hours use then

i guess using nos at the low end is pretty safe, even on a 500bhp+ cossie?

Azrael

By the way, what is this car for? Corners? Burning rubber? Killing Evos from traffic lights?


Chip I have absolutely no idea what would nitrous be for except in a drag-car.

Chip

Nitrous as antilag isnt really that great on a drag car as you never really come out of the boost threshold for long enough to need it once you are moving.

On a road car though its great, floor it and get instant punch rather than lag, great coming out of bends, or just when you put your foot down going from a 30 limit to a 60 limit or pull out to overtake a car.

Azrael

Well it depends how high your boost threshold is. I know they use it that way, but I don't know much about drag racing anyway.

I tend to like things that work with every tank full and don't need toping up between oil changes

Anyway who needs big turbo and nitrous for pulling from 30 to 60 mph?!??!!? Even standard Escos does this far too fast

Chip

iTrader: (3)

Ive never heard of anyone using nitrous purely as antilag on a drag car, makes no sense to me, why not just leave the gas running once spooled too?


Its not NEEDED, its just nicer to drive.
If you had ever tried it, you would know what I mean, but clearly you havent so dont.

And I agree a standard small turbo escos has nice response, but people who want big power end up losing that, nitrous gives it back to you very simply.

Azrael

From what I understand they usually have toomuch power to handle anyway when it goes on boost, but maybe it's left on - I don't have much nterest in that, I just remembered that some people where running nitrous setups that were supposed to help spin the turbo.


My point was - why not use a bit smaller size turbo, have nicer torque curve and QUICKER car all around instead of chasing numbers.

We did this with a Scooby recently - the 350bhp one proved much faster then 400bhp one in the same weight shell. Of course it's A BIT slower in the straigh line but much much faster in most other conditions and easier to drive.

How did things go today ?

Steve.

Gatecrasher

Went very well thanks for asking Harvey is a Top bloke went right out his way to make me feel welcome and Good how cool is his Grp A Escort

Left at just after 9:00am Thanet way Traffic, M2 Traffic, M25 traffic, M11 slow moving A14 Traffic, A1(m) Traffic and the small roads round Peterborough you guessed it traffic lol got there just before 2pm

Waiting for me was a stupidly quick escos that im not sure i can talk about a few sierras and Mike Goldbums Escos that Harvey took me out in to show me what a real 500+ Hp car is like on the road

after a nose about in the workshop and at the customers cars Harvey Dropped me to the Local train station in Mikes car

one thing i did find out is My Turbo is a Grp A T34.63 with a maram shaft and because its a Grp A it has the exhaust blades cut so it can run moocho boostyo and while this is good for more power and torque its not good for the lag side but saying that when i get it back i will have ALS and at least i know my current turbo is the most laggy turbo i will probably ever have on an engine

Its having longer studs put in the rear beam, water injection wired in, Coil pack fitted, Grey injectors fitted, Air injectors fitted, 2 stage boost, new rocker cover gasket and half moons and a total setup

All in all was a good Day cant wait to get her back now

Gatecrasher

This car is for FUN! Track and Road yes and killing anything that it comes across

Gatecrasher

Sounds good soon as i get the car back wheel book it up yeah?

Gatecrasher

So in an ideal world what would be the best Kit for what i want

My turbo makes full boost at the moment at 3500rpm and i am happy with that so i want nitrous to just get it to 3.5k a bit quicker but once that turbos on full chat then no N20 at all but as soon as i drop down below 3500 the nitrous is back on

Can this be done through every gear and be limited to each gear from 0rpm to just 3.5k and if so how would you progress the nitrous and at what level would you use wat amount?

sorry for all the questions but i know you like explaining things

cheers

How long is it going to be away this time ?????

We could ask Luke along as well, see what his new toy does before he mods it.

You need:

Single injector nitrous kit : http://www.noswizard.com/product_inf...products_id=58
Digital progressive controller : http://www.noswizard.com/product_inf...roducts_id=101
Boost switch : http://www.aquamist.co.uk/sl/plist/p...5/806-155.html
TPS interface : http://www.noswizard.com/product_inf...products_id=10 (these are a tenner cheaper if bought with a kit)


If you wish to limit it against rpm you can do so on the controller but I dont think you should do so personally.
On my car for example if im at part throttle at 4500rpm and I go WOT the turbo spools MUCH quicker with the nitrous than without, so I think you would still want it at those rpm too until the turbo is spooled, this is the value of the boost switch, it means that you wont EVER have the nitrous on once the turbo is spooled anyway which I suspect is what you really want, not to rpm limit it.

Is your ECU an L8, and if so has it been modified at all?

Ideally you need to still have the octane wires in place.

Azrael

For FUN car I would just get a dog-box and downshift a lot

Mike Rainbird

iTrader: (3)

Chip,
It's a P8 with the MTC board, air unjectors, wasted spark etc .

Chip

iTrader: (3)

Does that have any external way of taking off inigiton timing simply like the octane wires on an L8?

Gatecrasher

Chip i dont know mate how would i find that out?

As Mike said i have a P8 Ecu with a pectel board, ALS, AI, WS, ect

Chip

iTrader: (3)

Mike / Tony@Turbosystems / Stu

One (or more) of them will know, hence Ive asked Mike, if he doesnt know, we can start a thread asking the others.

Chip

iTrader: (3)

PS

If it doesnt, you may be able to do similar with the water temp correction map on the ECU, who maps it for you?

Gatecrasher

Mike?

Mike Rainbird

iTrader: (3)

No they don't. Also, I'm pretty sure that P8 can't do boost reduction for water temps either.

Chip

iTrader: (3)

That makes it a little more involved then, cause you are going to need to retard the timing to get away with a big dose of gas.

You can do it via the temp sender though I suspect, but you would need to talk to whoever maps it for you.

Basically you use a relay to swap the resistance of the temp sender out to a different value that you know you wont ever reach (like 150 degrees) and for that value you have a correction in the map that takes a few degrees off the timing.

Gatecrasher

Problem with that at the monet is the car isnt going ti be mapped until i get the new engine and for the moment i would still like Nos on my current setup.

Any other ideas, could Won not do it if i had them do the instal?

Martin-Hadland

iTrader: (2)

Ben,

You don't want NOS you should go for my external gate GT30 set up, I'm sure Doug S will agree.

Gatecrasher

Whats the spool up time on a external gate GT30 set up? I.E. when does it start and when is it on full boost? Why not both?

Gatecrasher

P.s. you have PM

good lad

tony mannock did a tt yb back when kylie and jason were still singing
in the bed together,i think the reason it didn't go further was it wasn't as
good as a nice big single one.

how do you drive it ben?? do you pootle until 3.5 then get going
or do you swap cogs and get it going faster quicker if you know
what i mean

Gatecrasher

I do Poodle about most of the time and dont get into 3500rpm unless i mean it if that makes sence

My problem stems from supprise customers, so for EG im minding my own and then someone wants a go, And anyone who owns an escos will know to well happens all the time, i have to drop it and then still wait for what i think would be called Boost thresh hold rather than Lag and this is what pisses me off

once gunning the car Lag isnt a problem through the gears is it is quite aggresive at 350+HP

My car was built to eat my mates M3 E46 and my current engine just isnt cutting the mustard and after me driving his over the week end in a little race and him in the my cossie i was a little disapointed at the Grunt is from 0rpm and does pull quiet nice

I wont have it tho i know when i get my 550+ hp Engine our other mate in his Gallardo will be getting Whooped 520HP 1430kg Briiiiiiiiing IT!!!

Chip

iTrader: (3)

They wont have the equipment to remap the P8 for igintion retard.

You could get away with a smaller dose without needing it, but you didnt ask for my input into a simple system, you asked for the ideal setup, lol


Martin's GT30 setup sounds good, but TBH if you drove that back to back wit ha T34 on nitrous (as a power adder not just as antilag) you WOULD prefer the T34, but only for 10 mins till the bottle ran out, lol

GT30 is a great match to the YB, take martin's advice, its money better spent than an expensive nitrous kit that costs the same, and keeps needing refilling, a bit of lag makes cars fun anyway

Stavros

I vote stuff the nitrous, madness to fit a 0-3500rpm nitrous kit, wizards of nos will have to sell it as the granny booster or summat, nobody needs power boost at a revs almost no performance engine on earth n/a or turbo has good power at

GT30 and external gate like Martin says i reckon, and learn to go over 3500rpm

Now to go in to Ginge-spec waffle mode... (but not about what he did at the gym today or how gangsta his mates are )

I can understand (from experience) that having no decent power before 4.5k becomes a chore, but 3.5k+ powerband sounds ideal, unless your driving round in 5th all the time surely your there or there about constantly?

Revving the car or not is a subconcious thing IMO down to noise.

Do you drive a normal n/a little engined daily driver? Surely your barely ever under 3.5k in that to drive pretty much anywhere? Your average 1.8-2litre n/a engine needs a whole lot more than 3.5k to accelerate.
BUT because its got a standard quiet exhaust it feels more normal to rev hit harder, as you dont hear it.

Personally I deffo end up revving cars harder when they have quieter exhausts, its a subconious thing.

On the other end of the scale though, rotaries are incredibly loud, so is my Chaser, but they both feel normal to pootle around even at silly rpms like 6.5k+ as they feel so smooth (due to rotaries and short stroke straight6s being like that) its like the rev counter is lying to you.


Amen

Chip

iTrader: (3)

Wizards of nos will recomend the same as I just did, NOT to limit it to 3500rpm, so please dont start quoting stuff as if they have said it when they have not and never would, only person who has suggested that is the person asking the question NOT anyone else.

Stavros

what? quoting who? i dont see any quotes or names

you think i was serious about a "wizards of nos granny booster" ? i was taking the piss out of him wanting to do it

need to lay off the crack pipe dude, youve gone nuts

Still want to do a twin charged YB .... What sort of supercharger gives best low down response??

Stavros

any rootes/eaton/lysholm type, especially when highly geared.

Gatecrasher

Time after time you see people talking about LAG on there cars and how people don’t like it or how they are trying to overcome it, im not the first and certainly wont be the last to ask questions and try to find ways in which to solve it whether it be Anti lag, Nitrous, Twin Turbos, Supercharges or whatever

my exhaust noise does not bother me one bit as i cant here it over the gearbox unless you are caning it and yes i love the sound of both so no i don’t drive round in 5th looking for an excuse to moan about Lag its just something that im trying to overcome if i didn’t like my car being noisy i would sell the escos and just use my daily run around A4 TDI

My Current T34 is more laggy than Mike Rainbirds T4 on his current Engine in his car which i went in Monday and to be honest the only reason i thought that Nitrous may be a good ideas is like i said at the weekend i was driving my mates M3 and the way that pulls from 0rmp to 3500rpm would be nice.

I don’t Care what anyone says if you can have unlimited boost as in Turbo spools up from 0rmp and by say for E.G. 2000Rmp you was on full boost and the power was unlimited, everyone in the country would be doing what you are doing not just Cosworth owners

Gatecrasher

Yeah and while wear at it everyone forget Anti Lag, Forget any turbo that comes in lower than 3500rpm Just learn to Rev your cars you know the pedal on the right
