To kick start 2013 in true trend setting fashion, Torque Italia launches another unique high powered 500hp platform. The TI 2.1L Stage 5 engine is producing a healthy 520hp, 440trq @jaw dropping 2.15bar, with peak power arriving sharply at 6273rpm, and very driveable it is too.

Specs are as follows:
Forged 2.1L 20v
TI stage 5 Big valve head, plus C&B cams
DTA PRO S80 ver 63 running a 4 bar map sensor
925cc injectors, Bosch Motorsport 044 inline pump, 1.5ltr Surge tank
Tigart exhaust manifold (ceramic coated)
Tial MVR 44mm ext WG.
Garrett GTX3076 .82ar,3 inch Vband turbine housing.
ITG Maxogen air filter
Full 3.5inch exhaust system.
Helix cerametalic 6 paddle clutch, uprated cover.

To start with at current power levels, we have been forced to cross over to a more bespoke and specialized management system that offers greater consistency and reliability. I personally went with the Dta Pro S80 ecu for cost, broad base functionality and most importantly the tuner, who is well versed in mapping the 20v 5 cylinder engine for over several years now. To complement the expertise with management system, a Land and Sea DYNOmite water brake testing dyno (industry standard) was used to calibrate the platform accurately. Accuracy and consistency being the key here, so all runs are performed in 4th gear also for 1:1 ratio.

A brief insight to the workings of water brake dynometers.
Water brake dynometers are some of the most popular devices for engine dyno testing, ideally suited to the testing of high-output engines.
Water brakes use water flow proportional to the applied load, to create resistance which test the engine’s output. A controlled flow of water through the inlet manifold is directed at the centre of the rotor in each absorption section; the water is then expelled towards the outside of the dynamometer body by centrifugal force. As it is directed outwards, the water is accelerated into pockets on the stationary stator plates, where it is decelerated. This continuous acceleration/deceleration of the water creates the applied load to the motor. Through this transfer of energy, the water is heated and discharged. The main benefit of water brakes for the mapper is the advantage of steady-state load measurements, which allows running at higher revs while still retaining accuracy and repeatability.

For road testing, JDM dyno facility has access to Kirbride Airfield (frequently used by Msport, Ford WRC team), so no excuses for real time runs in 4th, 5th and 6th for extreme load condition calibrations.

Now back to the 2.1L platform in action.

Working closely with John, we took full advantage of all optimizing capabilities of the DTA and set the parameters to suit my extreme driving demands.

First impressions, the part throttle and off boost driveability is far torquier than I’d expected, so a bonus there already. Idle is rock solid, no murmurs or palpitations to irritate. Power delivery is very smooth and progressive throughout the rev range as 2.15bar is force fed, leaving your senses discombobulated. At that intensity of power & revs the engine note is AWESOME! The massive 440lbs of torque is a first,on pump fuel.(from 2.0L engine)
The power band unleashes its ferocity from 3750rpm straight to the limiter. Through the gears right from the magic 3rd to 5th the speedo could be mistaken for the rev counter, hitting its massive 2.15bar boost ceiling every time and holding. Amazingly the boost profile mapped through the DTA software gives it superb consistency every time. Traction’s mind blowing, even in the less than favourable conditions we are facing lately.

John (DTA mapper) commented that he had never experienced traction issue on his dyno… ‘till mine turned up. Traveling north to the Scottish borders up from the most South Westerly corner of London takes just 1 full tank averaging 370-400 miles, not bad for a 520hp daily driver.

Being a frequent visitor to mapping and dyno facilities across the country I got used to supplying full tank of fuel for mapping sessions (£100+), JDM used half of that from start to finish over three days which is testament to his experience.
One extra enhancement to add shortly is the E85 map ready for SPA italia

Note; key comparisons will be submitted against my old 2.4L setup once I’ve got my new/old graphs from Surrey RR on Feb 2nd.

Big Thanks to Rob40, F1Ang, Jbt and Shaun for their support,and of course, John at JDM dyno for his expertise.

Enjoying the Power again!

Barbz

Wow Great read barbzs.

Well done!!!

Nice to see the coupe is still Progressing with the times standard and tuned.

Your time and knowledge is A testament to your results.

Keep up the R&D work.

good result Barbz and looking forward to seeing it on the rollers on the 2nd feb .

440 torque???? WOW

Good results Barbz and to all involved.

Great write up and I'm sure the Coupe is great fun to drive. As above, I'm looking forward to seeing it next weekend!

Why did you decide to go from a 2.4L to a 2.1L?

Simply awesome enjoy

Fantastic results Barbz. Well done too those involved. Keep up the good work.

Welcome to the DTA club, took you long enough

Wow wee!!!!
The old master proves his worth once again

The new" high boost hero" :-)

Glad to see you're running proper boost now!

Whats the explanation for the dip @ 5k?

afr and boost are constant..

Wheelspin.

Nice! Huge torque right from the start!

honest, solid power figures - one of the few!

Well done.

This has been a major transformation from a lag monster to a truly driveable weapon.
When I first picked Barbz's car up to get the new ECU fitted, it wasn't the easiest of cars to drive; a little lumpy, off-boost driving wasn't great, the boost was an on-off switch--all or nothing. Clearly the standard ECU is way past it's optimum limits at this level of tuning and performance.

I've been using the DTA for over 8 years, the first in the uk on the Fiat 20v engine.
John had to start from scratch as there wasn't a base map to work from and this obviously took a long time to develop.
When there were people on here slating the DTA because the software wasn't developed enough to run the Fiat lump, John just got his head round things in his own inimitable way!

He has been a DTA agent for a long time and has pushed them to develop the software to enable him to tune my engine.
It's all a bit beyond me but in the early days he used a 10 cylinder map and then started dividing the values to suit his needs, you've got to take your hat off to him.
Then he used a 6 cylinder map and sequentially omitted a cylinder in turn to keep the 5-pot arrangement.
When DTA finally gave him what he needed to run these engines properly, the only limiting factor is your wallet and Barbz's know-how!

I'm pleased Barbz has taken the DTA route as an affordable alternative to the mega bucks Motec system and now he can appreciate just how good all his hard work really is when it comes together in a well made and balanced package.

On the drive down to meet Barbz, the transformation was amazing. Off-boost driving is a pleasure, the power build up is progressive and linear, and when the boost kicks in, you know about it! The highly efficient head work is noticeable not only at the top end but at how frugal the car can be if driven carefully. Carlisle to Birmingham took just over half a tank, that's 200 miles of mixed motorway driving!!

I think it's time to crank up my boost a little, 1.6bar and 460 bhp is soooo yesterday!

High boost Hero's
Be wary

Excellent result Barbz

Well done guys

WOW!! looking forward to a lift round Spa in that Barbz, i'll try not to shyte myself too

If I were you Proccy I would pm Sean-c as he was foolish enough to go out with that fruitcake.
Changed him.really understands the value of life now.

I had a few laps with him last year and it was epic - i dont think the car went forwards much it was all sidewards lol, brilliant

Outstanding work gents!!!

Great write up barbz, i did have quite a bit to comment, but dad has pretty much nailed it on the head there.

It really was an absolute privilege getting to drive the car. I only experienced 1.4 bar, but even at that the performance was breath taking. i struggle to imagine the difference in performance from 1.4 to 2.15 bar..... The words "savage" and "certain death" spring to mind !!!

It truly is amazing, the fact that you can now have that much power at the push of your right foot, in a front wheel drive, road legal car, and yet it be useable, drivable, tractable and to a certain degree even sensible! I mean driving it from A to B through town, in traffic etc, apart from the slightly heavier than standard helix clutch, and the fact it would be slightly louder with that 3.5 inch exhaust system, you really wouldn't tell it apart from any other coupe, i could and would happily drive it around town all day long. Off boost driving was an absolute joy, you can really feel that head work coming into play with the sheer amount of torque the car has off boost, Driving it just feels so effortless.

I could go on for hours talking about this car, from the performance, to how well those huge Porsche brakes work, to how planted the car feels on it's custom suspension setup, but I'll be here all night

it really is a truly amazing machine. A huge well done to all involved, but especially barbz for building such capable platforms, i don't think the guy gives him self enough credit to be fair.

One hell of a way to kick off the new year, really excited to see what this year brings

Ps. I'm also REALLY looking forwards to a 2.15 bar passenger ride around spa people will be queuing up like its a rollercoaster... "tickets on sale over here please"

Good Job Barbz!!!

I am excited to see it in spa

French also have some surprises!

How you getting on with your car Marc?

I haven't been on French forum for months.

Nice results Barbz.

Going to drop you a PM about a couple of things

My poor 2.4 finally succmub to bore wash. ,thats why i jumped ship to a standalone.
At this level of performance and cost of mechanical hardware the OEM system was not suitable.

great job!

I like the "not bad for a 520hp daily driver"

Looking forward to seeing this at Surrey RR!

I put a link to this topic on the french forum, we'll see some reactions soon
I hope to see you at Spa
