lag is the time taken for the turbo to start boosting properly after throttle ? you will be able to see when boost come in on the graph but not when the pedal was pressed?

Lag is the time taken for a turbo to produce full boost once at the rpm it can produce full boost at. Most folk on here seem to confuse lag with boost threshold.

lol @ nick
im just quoting the figure out of interest im not claiming it to be 100% accurate. its just the only figure I have
if it ever goes on a dyno out of the car i'll update
pee vee
it feels a lot laggier now due to two differences.
first difference is this maps not finished yet so its losing a litle power offboost and second is its got loads more power on boost now
so where as before it wasn't much diferent on or off boost now its night and day.
will take you out again some time. its nuts at 6-7k easily comparable to dougs escort or porkies old 3 door in terms of the shove in your back
dingla. I figured if I have a nova it may as well be a weird one. lol
danny. yeah the engine has more scope than the chassis or transmision really. needs to be put on an m32 box and put in a vx220. lol

300bhp can be done for peanuts and in a stripped nova weighing only 800kg is mentallyquick.
Thats enough to give 250@wheels, which is over 300bhp@wheels per tonne
So you get the same sort of acceleration at normal road speeds (ie 30-120 or so) as you would from a 500bhp escos
Properly cheap way to be very quick

its funny seeing subarus, evos etc being wasted by it.i used to own a nova sr running twin 40s,big valved head fast road cam etc that was such a fun car also, think if i get a nova turbo ill want about 320bhp which is more than enough id say for on the road, mind you i want get the r5 over 200bhp before summer

On the road a proper 300hp nova is brutally fast and lets face it thats a stock let with some chips, easy on a small budget.
Throw a Gt30 on a half sensible engine build and your well over 400hp and that is about as fast as anyone would need to go on the road.
Gavs Corsa although more mismatched than most is ridiculous when its on boost, chews 5th and 6th up like most RST's do 1st and 2nd and he'll admit the powerband is VERY narrow so giving nothing like the results on the road a LET does with a GT30 strapped to it.

A genuine 370bhp in a fiesta turbo at only 900kg would be monstrously fast and would destroy a 500bhp escos from 30-130 where grip isnt an issue.

Yes Pee Vee meant boost threshold when he said lag to describe the wait for the boost to come in versus RPM, and yes I meant polycarb when I used the term perspex to just mean generic clear plastic.

I knew what Pee Vee meant anyway and it was me he was talking to, but its always good to clear up the boost threshold and lag thing as so many people misuse it so thanks for taking the time to do so.

As above, I dont actually know the exact grade of plastic used, never interested me enough to find out, firewall was already in place when I got the car and ive never needed to change it.
especially at only 22 psi

The VXR guys have problems with over 330 lb/f t's think the vectra f40 gearbox can take more power but not sure if it's very compatible.

Normal upgrade for an ACT with the F23 that I have, is to move onto the M32, and generally they work better afterwards.
F40 box would certainly take the punishment though, but you're getting huge then.
If my F23 will do a half a season on the power Ive got now, i'll just keep swapping it out, as they are only about 150 quid anyway so its not a problem to just throw another one everytime I change the clutch and hence have it off anyway.

Nice m8. Would b nice to c that power out the 5 but like yours my box will die.
What sorta times, 1/4s u seeing? I would have thought mine would b pretty similar, bit less at 420ish bhp but near enough.
Also have you got a graph to look at?
What's yours like at making boost in the lower gears? Mine struggles to make boost in 1-3rd gear, think it's down to cam timing in mine tho(too retarded)
would b fun to c it's and mine side by side.

They are heavier cars doing big road mileages, mine is a very different application really, so I think I will get away with a lot more power on one than they do.

Pretty sure the M32 can be rebuilt, you can buy the parts from fiat or alfa just not from vauxhall.

Stu, no idea what quarter time it does now, will have to take it to central day or something, sadly no quarter mile strips particuarly near me, even our 1/8th mile track got closed down.

Yes mate, although more or less all of it has been redone since then, as im now on a totally different engine/box with different mounts, different suspension, different subframe, different gear linkage (its on cable now where as was rod) different clutch setup (its now on an internal slave hydraulic setup not a non hydraulic box) ive welded up all new mounts and brackets etc, only things that remain of the original conversion are basically the firewall, a few bits of box and tube, and the petrol tank, so its about 20% the original conversion effectively I guess, oh and the ghastly looking but very effective headlights were already there too, lol

Yeah:
http://www.youtube.com/watch?gl=GB&h...&v=4S8O-Eoaprw
Its changed a LOT since then though, Ive cured the bump steer, its about 50% more power now, and Ive got a much higher rev limiter now.
also in that vid it was on narrow wet rear tyres as I trashed my slicks earlier in the day
so it doesnt really reflect how it would go now
