Komotec 460 or SSC TVS1900?

[Swiss380Cup]

@550superfast Come to Paul Ricard, Mugello, or Imola in summer when it's 37 ° C outside, and you'll see for yourself. I don't know about the heat soak problem on the EX 460 or the TVS 1900, but as regards the standard V6, it's clear. And my guess is that charge cooled is better than non charged cool. Especially in those temperatures. Probably on the UK, Belgium, German tracks it's less of a problem, but it's not the closes for me....

Hi Guys,

Stu from Simply Sports Cars here. I've been following a few threads on this forum but this one has slipped past me for some reason but I'll be on top of it from now onwards. Apologies for the delayed replies to some of your emails. We have had 4 Events in the last 4 weeks which have stretched the resources to say the least but we are back to full steam ahead here in Sydney with no more major interruptions for the rest of the year. If there are any questions I have missed or emails that I havent replied to plese shoot them to me again now > stu@simplysportscars.com.

To bring you up to speed on the charge cooled TVS1900, we are finalising fitment of our development kit at the moment and should hopefully have the list of items that make up the kit so that we can finalise pricing in the next couple of weeks. I'll share results etc once we have them with and without our new header system.

I have a bit to catch up on but I'll put together a post with my input on some of the questions and claims in this thread in the next few days.

Stu

What information do you have on heat soak then? Have you driven the TVS1900 and Ex460 hard on track lap after lap? Or at least been on track where these modified cars are running? Or do you have data provided from the tuners?

There ist a heat soak problem, i have driven the stock V6 in Spa Francorchamps Dijon Nürbrugring in the hot summer time, the engine cuts the power when the inlet temperatures are to high. Later i had the Ex460 in my V6 and it was a huge difference, please have a look at the KT graphics. 

KT Text, Test EX460/ Spa Francorchamps summer 23 - 29 Degrees

After a relatively short drive, the charge-air system as a whole achieves its "system temperature" (approximately 40 ° C), independent of the heat-down or supply of the peripheral intake components.

Temperature changes are then - simplified - only dependent on the applied boost pressure.

At full load (Kemmel straight in Spa) the charge temperature at the front of the radiator at 85 ° C and after the radiator at 48 ° C max

Thus, the intake air mass at maximum boost pressure is 15% higher than in a version without intercooler.

At high speeds, the charge air cooler tended to increase, indicating a high proportion of the water cooler to the heat balance of the overall system.

 

Red graph is the airtemperature before cooler

Blue graph ist the airtemperature after cooler

I'm looking forward it sounds great

[Swiss380Cup]

@ Stu ... hi there, we're eagerly waiting for your finalized cooled TVS 1900 on this side of the world....I know it's summer time soon down under but still don't forget about us. We all have our winner time to think about what changes we want to make..... The trip to Sidney is a little to long to have a chat, so we will stay put here for the time being awaiting for your news.... there could be a huge fans crowd awaiting you

[GFWilliams]

It's amazing you guys are still discussing this, in the time this discussion has taken, I've had mine tuned to 460hp and had a lot of fun in it!

[tim_marra]

Hi Stu, I emailed you recently for news on the TVS1900 for the Evora. Please can you let me know when you think it will be available?

Thanks

Tim.

So @550superfast and @GFWilliams did you guys play together on track at Silverstone and can feedback differences on the straights between your cars ?  

[550superfast]

No - the day was very very busy, in fact probably the busiest track day I have ever been on. The EX460 should be quicker as it is making more power, but my car will be a little lighter and has plenty or torque.

A Cup is significantly lighter than my car, amazing how much difference this makes. Martin (@mcx) was doing very well when he was following me and he was in a standard Cup!  Without the power upgrades I wouldn't have seen which way he went...

@GFWilliams sounds like you will have to shed some weight ... battery is a good starting point

I'm a bit undecided what to do with my car at the moment...  Tempted to put standard suspension back on and use it just for the road for a bit.   Getting too expensive for me to track it... 

[NW76]

@GFWilliams you are drifting too much ? ? ...  

Seriously ... you have been hit with a lot of maintenance items in one year (clutch, gearbox etc) ... this will averrage out over time. I have been tracking mine since I have it and I found it to be quite reasonable at least if you compare it to the likes of Porsche, BMW Ms etc ... all in I am at less than 1k EUR a track day (incl track use fees, insurance etc)...

I do that in tyres alone 

[NW76]

?... you know what ... you should get a couple of sponsors then ... Pirelli or Michelin might be very happy to foot that bill looking at you social media presence ?

Maybe you can ask them for a couple of Trofeos for me too ... 2 sets a year will do for me ?

Haha, you definitely had a reasonable power advantage on the straights,  I suspect not taking the corners at a constant jaunty angle might help too     (with running costs too) Does look great fun though. Did you get the lsd fitted?

I've been lucky so far with my exige, one set of ZZR since I bought it in March, 9 trackdays, still have a reasonable amount of tread,   one set of brake pads. I decided that the RS I had was too expensive for track when after 6 trackdays, a set of pads was £1300 + fitting, and the rear carbon discs were 45% worn, and £10k/axle.  I don't think there are many cars as quick as yours that you could run on track for much less, maybe you've been unlucky  

[NW76]

Absolutely right ... track a 991 GT3 RS, McLaren or Ferrari and you need a trailer - but not for your car rather for the money you will need to maintain the car ?

[Swiss380Cup]

@mcx Yes I remember my GT3 running costs... it would cost me around CHF 20-30k per year for about 8-10 tracks... and most people with PCCB put standard discs for the track, far less expensive, but still a few thousands. And you can count on having them changed 2 if not 3 times a year.... + pads, + oil changes, + tires, ++++++++

There's a difinitive advantage for Lotus in running cost....

9 trackday on a set of ZZR tyres

How many laps each day do you complete ?

3 days and my ZZR tyres are toast!!! About the same on Trofeos as well. I normally complete 150-180 miles each day

Tbf 3 of those wet and one brands indy which gets a bit dull after a few laps  .  Have done a few private track days with plenty of laps, maybe i'm just easy on the tyres ..

Not sideways enough 

[chumaxa]

I do not understand the standard suspension part, why don't you just use it on the road with the nitron system ? It is better, what is the point to remove them ?

@Simply Sports Cars Any updates?

thanks

[Mark030358]

How long does it take Komotech to do a 460 upgrade in Germany? I know its two weeks in the UK as the supercharger is sent for a new pulley? Anyone give me a time frame?

cheers
