I guess my clutch will be fine then. If yours can take 250@ wheels lol.

So a turbo that can make 250hp.okay

What clutch do you have? My car 'only' makes 230lbs torque though.
It's rated to 250lb ft. Torque increases with boost.

Yates saxo would be ideal to buy and drop a duratec in!

You could be a 250hp duratec for the same sort of cost to get 180bhp from a tu16v

What you waiting for? If you need help I'd love to help with the first duratec engined Saxo. You cant moan at that offer

stevo1600 · 6th December 2011, 23:34

Duratec engined Saxo sounds lush. I'd love to see something like that tbh.

250hp would be nice, but I wouldn't make as much torque as you surely? Yours is 250 atw mine would be 250 ATF. Seriously that would be an immense vtr lol.

Achievable on decomp?

What are people's thought's on Nos?

In my eyes, cheap and easy for instant power. I guess the refills at £xxx a time would wrk out expensive.

Well if you ran a smaller turbo at more boost pressure it would make more torque, or if peak power weren't so high it would make more torque.
Say if you had a smaller turbo running the same power as me it would produce similar torque to hp for example but a lot more boost pressure required. That's the nature of a turbo/engine.
This is why rally/touring cars 'only'have 300hp but nearly 500lbs ft torque as they use a restrictor and run mega boost pressure.

I don't mind not having as much torque but having a wider power band, this makes the transition from off boost to on boost much smoother thus putting less strain on tyres/transmission.

Lippys nos,d vts was a very good setup. Personally I think it's a good cheap mod to start with. Just depends how many times you would use it as would start to get expensive every time you refilled. can't remember costs of having the bottle filled now.

Has Nitrous ever been a cheap mod?? parts are expensive, constant gas refills etc. Not to mention if it aint set up right.

logic_guy · 6th December 2011, 23:51

Well when people say "1 Shot". Really, how much or how long is one shot?

I'd initially use it 2nd, 3rd and 4th gear gear probably up to 70mph or 80mph. I'd mainly use it for acceleration.

I'm really interested in rorz_vts kit that's for sale now. Combine that with a Ph3 cam (along with my vts gear box) i think i'd have a relativity nippy 8v car.

I just want some more thoughts/ inputs.

stevo1600 · 6th December 2011, 23:52

I guess running mega boost pressure would cause lots of lag on rally cars though? Unless the smaller turbo helped to stop lag....

Which is what I want to avoid. I had hardly any lag on my r5 turbo, it would be nice to not create any lag or as little as possible, with better power

I regret typing cheap. The kits aren't bad, but still above 400 quid for a good setup. The refills etc

Rally cars use anti-lag

Why are you changing turbo? What boost pressure were you running before? Why don't you just turn the boost up a little? It's amazing the difference a properly mapped car and a few extra psi can make. There are gt25's that can make 300hp so why don't you buy one of these?
There is no real cheap way to lots of power without a risk.

stevo1600 · 7th December 2011, 00:01

It was on 8psi Danny. I used an r5 t2 turbo. This won't push me above 200surely. I have a standalone ecu, and will be mapped same place yours was if they can map megasquirt?

Changing turbo as mines to small. I'm also fitting a decomp. Gt25 sounds like a good idea, and was my original thought of turbo.

dannygti · 7th December 2011, 00:04

A proper gt25 is a massive step up froma t2 mate.

You run 10psi on a gt25 and get it mapped properly it will fly

Phone northampton Motorsport up and ask if they map it.. If they do I guarantee he will do a superb job.

Sophia_Bush · 7th December 2011, 00:06

I have come to the conclusion the next build will be small cc again with well through out cooling and a modest aim of adding at least 100bhp to the original engines output

I agree. I'll opt for the gt25 and just wind the boost up until I'm happy.

I'm sure they would map it. If not I know luthor on here does. Will phone closer to mapping date.

Ill ask him tomorrow ill be at NMS. Got a funny feeling they dont though as im sure they wouldnt map the predator. I could be talking absolute shite like lol.

I can't wait.

selling mf2,sigcon,5th injector alloy boost elbow, 5th injector, t2 turbo.... Just incase you wish to keep it cheap as chips.

That's a good idea. A gt25 at 1bar is going to make easily make 200hp+.
That's a big jump from where you are now. If say 8psi on a t2 you will be around 160hp or so. To make more than 100% of the engines power is awesome.

I'm over the moon with how mine has worked out, weren't really bothered about figures, just so long as it was fast. Turned out to have both. I've almost put 150% more power through the engine which is amazing really.

I need to come and have a look at your motor soon to see how it's coming on

stevo1600 · 7th December 2011, 00:43

Haha I can't wait to see yours either Danny.

Soon as I'm back on track after crimbo and it's near completion you can come have a look mate. few suprises in store lol. I hope to push it to 1 bar so good stuff.

150% is immense, amazing what these engines can take really. I suppose it's how it drives which should be the main aspect when building a turbo charged car. Not powr figures. I'll have to ride passenger in yours next year and see what I think
