l have dash 5 on my setup and personally l do not think it will give you that rush you are after. If want that big shove in the back feeling go for a big single. If l had to do it all over again thats what l would do.

I cannot see how 380-400rwkw of -5s wouldn't give you that feeling?

Having been in a few -5 cars, and hopefully taking one for a drive soon just to compare that to -9s, they certainly pin you to the seat when setup properly running 20-22psi/380rwkw or so with a solid tune.

But then each to their own as you said.

yeh big single for the kick in the pants feeling... went in a 33GTR with a T88... was only putting out 360kw but the way it delivered boost was completely different

lag lag lag... then WHAM... big rush of power

lol 360rwkw outta a T88?

-9 equipped car with less power would most likely still be faster :)

If you just want a "rush" drive the car and hold throttle @ 4000rpm and then plent the foot. Same as a laggy turbo :D

Nismoid, my car is making a "claimed" 380RWKW on 25 psi of boost and was built and tuned by the same guys that have done your car. Comparing it to other GTR's running big singles such as a TO4z which is what l wanted to do in the first place but talked out of, stating that a twin setup using these lady -5's will be quicker. From my experience when both cars on a rolling start and in there boost range the big single always wins and feeling you get as you are thrown back in the seat is much more intence. The only benefit l see using my setup is the stock appearance and it may have a little more bottom end, which at the end of day l would rather have something with more top end and doesnt tapper off like my lady setup.

well T04Z cars would be making another 50-60rwkw given they usually run over 400 with ease.

Having been in various cars, im pinned to the seat with -5s.

obviously a bit more lag and another 50rwkw or so is going to feel different.

If the big single is better as you say, then the -5 equipped cars wouldnt be doing the faster lap times compared to the guys with the big singles from other workshops close by :)

yeh the car just got off the boat with that setup and was given a quick tune to see what it could do... D Jetro AFMs were maxing out or sumthing so it was being held back..

still the sensation a big turbo coming on song is very different to twins...

every day driving the twins for sure but from my exp a big single is needed for that the big rush put you back in the seat feeling

Apparently you've never compared the torque and power curves for a car, where often torque will start decreasing near the top end, while power continues to increase.

I know what your getting at, the comment he made was misleading.

HP = Torque x RPM ÷ 5252

So torque and power are proportional. More power means more torque at the same rpm. Given that we are talking about the same engines we can disregard the rpm part of the equation.

I have heard a few people say that the single turbos hit harder than the twins. Are you sure the twin turbos compare exactly in size to the single? I mean air is air? Do they both have even quality of exhaust manifolds etc.

Would -10s compare more to a T04Z instead of your -5s?

yer i got 300kw and its boring as, but ive been in other 300kw cars and its wow stuffs me wot the go is.

Hmmm just had a quick think about this. What other cars are you comparing it to? Do they use less revs?

If they use less revs then, they are actually producing more torque to make the same power. The higher torque figure could be what makes them feel more 'wow'.

Torque = 5252 * HP / RPM

If the big single is better as you say, then the -5 equipped cars wouldnt be doing the faster lap times compared to the guys with the big singles from other workshops close by :D

Concidence with car setup, driver etc? I am pretty sure Superlap was dominated by guys with singles on even smaller motors :( The quickest NZ track GTR I am aware of runs a T04Z. The odds are a quickest track GTR would be running twins because the majority run twins anyway...
