Combination of factors, large turbine wheel and housing, large non billet compressor wheel and race profile camshafts.
To be fair this is the game you play, if you want lots of top end bhp you generally have to give something away elsewhere.
Bare in mind of course these results are on straight VPower and that meth and or race fuel make a huge difference in torque due to the available extra ignition advance.

I think it's a brilliant idea, let me know if you want me to sort it.

Martyn

 

Pm me a price

 

Will do !

 

Wiz of nos dry kit Im thinking

 

Me too, quick 50 shot in the midrange should give approx 90bhp more midrange with the aid in spool.

 

50

 

Trust me, 50hp put in from 3000rpm to peak torque will pick up a fair bit of power, don't get power hungry, lol.

 

P.S Don't forget, it isn't 50hp at one point, it's another 50hp at every point in the rev range until it gets fizzled out by the management.
Add to that the quicker spool and earlier boost and 50hp becomes 90hp

 

Which race fuel would you be using, what octane? Would the difference in torque be how much it makes, or the torque curve coming up at lower revs, or (I presume) both..

 

What is a dry kit? Seen the wet kits though.
Regarding the Nos, is this still used at wide open throttle position? foot to the floor.
Or have things moved on so it usable inn various throttle positions?

Intreased on your thoughts Martyn.

Just had dyno run, at 514H.p/ 550 torque 2,5 T25. last night.

 

A dry kit uses the engines injectors for the extra fuel the basic wet kit uses wot! But the dry kit via ecu (syvecs) can be programmed to add n2o at any point.

 

Gus is going to have a 20% methanol map for his play days, although I would love to do a map for Q16 race fuel as we had an excellent result on the last car we mapped on that.
The increase would be right through the rev range with more torque and bhp coming earlier in the rev range.

At Gus's request, here are the results of a similarly equipped 2.1 engine using Cosworth fast road camshafts and a Scoobyclinic Billet 35R .82.

VPower @ 1.9 bar.



Q16 race fuel @ 2 bar



Note how even at 4500rpm and before peak boost it has gained approx 80hp from the higher octane rated fuel.

When you look at this cars graphs and Gus's in more detail, you can see exactly what we were discussing earlier re spool vs top end punch.
Stus car whilst spooling much earlier doesn't hold peak power much beyond 7000rpm on the dyno.
Gus's whilst spooling approx 500rpm later, holds peak power for over 1000rpm longer and this perfectly suits his intended application.

Q16 can rock.... I can substantiate that one. However, at the price, you wouldn't want to get too used to the power increase it can give. lol

12degs more ignition and boost untouched, it gave an additional 80bhp on my old engine.

 

Q16 map it is then!

 

Thanks for the reply Martyn......Interesting.!

 

Just wandering, is it a case of race fuel as above or a shot of Nos, or can it be both at the same time?

Lee.

 

It can be all together

 

 

Thanks for the details for the dry kit Nos.
I always thought that that you had to use wot, for Nos. I would be very interested in getting more details on a dry kit just to add a bit of power. And not at full throttle ,
I am running Syveccs so could be installed with no problem .

Maybe later next year and will see what Martyn can do for me .

 

should of kept your saff gus lol

 

Very nice mate

 

Q16+2.2bar=708bhp 520ft/lb! Job done!

 

 

Fair play gus,thats fookin awesome mate

 

Wow 708bhp! Bet it's a monster/handful on the road!

 

That's Q16 for you.... But at the price you'd be pretty pissed if it didn't make those kinds of increases.

 

Think its too late

 

decent jump in power!!
gus loving it

 

It's started again lol trying a gtx35/82r and 100 shot o nos hopefully 800plus with race n gas
