got the fd dynod today

[Grant Monkhouse]

with probaly twice as much torque!!
laptimes, terminal speeds and times are good indicators of power
 
and also biiiiiiiiiiiiiiiiiigggg burnouts:D;)

Ok just to clear this up 100% because this is well off track now, out of Intrest have any of you had both Twin turbo set up and Single turbo set up running decent power? Lower HP FD\'s are more Fun to drive on twisty roads and short tracks, Big HP FD\'s are much more fun when you have a decent Strate or a Dual carrageway.

Hence why i say Twins are more fun.

The only place in the UK I would take my car for an even remotely honest dyno assessment is Surrey Rolling Road.

Honist? be carfull using that word

I thought you where clued up on Dyno\'s, i Would never Use a Barrel Dyno, not only does the wheel size and Tyre type play more of a Factor you don\'t have to use Straps on a Hub dyno. I don\'t think its the Dyno you mean but the people who use it?

[Grant Monkhouse]

i will be having my car on a hub dyno, simply because i dont want it falling off. loll

[Grizzly]

LOL that too

Always fun watching this (not that i dislike evo\'s at all )

hahahahahahahahahahahahahahahahahaha seen that before

[Grizzly]

Do you think they bought some better straps after that (well both of them lol)

[Grizzly]

Just watching some Dyno fails and this poped up http://www.youtube.com/watch?v=z5TWJ0Tbizc not seen this vid for years (must have been done 10 years ago now), Scoots Semi P/P doing a 700hp run back in the day

There is nothing inherently wrong with a barrel dyno. The software, or rather how/who sets it up however is a whole other horrible can of worms.

What is the car being used for?
Just to clear things up I have no problem with stock ports, with small singles and twins its not worth opening the engine up for a marginal top end gain which will be limited by the turbo anyway.
I like the twins, when I map them I run the first turbo higher i.e 1.1 on the first and 1 bar on the second turbo, this smoothes out the power delivery and gives a great bottom end
Imho
The only down side is reliability of the rats nest, if the simplification is carried out it should be fine. Plus the cost is a lot less than going for a small single.
This is if I wanted @ 400 anymore then single

Jay what would be your opinion on either a small single turbo on stock ports or the twins with all the complication. Not asking for any trade secrets, just what you would prefer.

What size turbo would you use etc?

For a street car, the OP was wondering about upgrading to the BNR twins, I think, just to gain the ability to run more psi, 18psi. Although I said for the cost and the gain it would be a better option to go for a smaller single turbo.

A gtx35R or possibly a gt30R. These would be good for 450hp, especially the gtx35R. And still give good response, not as quick as the twins but close too it

[JayDee]

I would go small single rather than bnr, I would worry about the heat build up with a gt30
with prolonged hard use on the turbine side.
The best street turbo for a rex I found is a kkk27 t3 flange, full boost by 3600 and went on to 440 atw in 2005 a to4s or a t62 all work well without the cost of the gtx turbo

The GTX series only seem to show their benefits in practise up top. There is little to be gained at bottom end from the applications I\'ve seen them in so far.

So it\'s only 1,000 rpm spool up slower but much greater power. Plus once your rolling you would be doubtful to go below that rpm, if a driver did then they clearly not drivIng hard enough

[Grizzly]

Yeh would make a good Upgrade but ££££ the twins make the best road car and if you wanted anything close to it you would have to spent what 2k?+ thats if you could lay your hands on a K27 kit? (i like the big Rx6 too )

So the way i look at it you ither run twins at 350hp or you go for 500hp because there isn\'t much diffrence in the prices to do anyway. So the question is what is what do you want?

The best way is not to bother, Have fun in your FD then when you want to get more power sell it and buy a decent one done, you will save a packet. (by that time you will be able to spot a lemon )
