I'm debating one of these at the moment. Is it worth it for the CTHE engine? Also stuck between the two providers, tmc just seems massively expensive in comparison.

As far as I'm aware, TMC and Bluespark boxes will not make any difference to CTHE engines as they are already running more power than their CAVE siblings.

 

With regards to who is better......... well that's a different kettle of fish.

 

I personally prefer TMC as they have 3 channel box compared to Bluesparks 2. TMC monitor and control boost, air flow and cam position.

Even if CTHE do run at 190-195 etc. The tmc/ bluespark push over 200 each. Reading back over a few posts cave + bluespark has been dynod showing 201+. I'm more intrigued as to anyone running cthe with one and their experience.

That's not to say that they don't make difference as you suggested to the CTHE engine.

Well a TMC box with an ITG induction kit and resonator delete was dyno'd at over 210BHP.

 

So who's to say a CTHE couldn't get that or more?

 

All boils down to whether you want to spend a chunk of money of potentially just 12BHP?

It's not just about the bhp gain. You can't chase numbers like that. It's about driveability. You can get a sky high Peak power figure but it only hold on to it for 500rpm at that top of the Rev range vs a lower figure that holds across the majority of the Rev range. I know which I'd prefer! That's why I'm intrigued as to real world driveability from other cthe+box owners. Still 210 is a nice figure for these cars, would not say no!

I've still seen no evidence that a CTHE has more bhp from standard.

I'm new to the vrs scene, but same with me. In which case, the units should theoretically function to the same level imo.

The CTHE is the revised engine, although some can still use oil, the uprated parts and map have been proven to produce more power and deliver it in a different way.

Has there been a stock dynod comparison between cave and cthe on the same rollers, same day, conditions etc? Be interested to see the graphs if that's the case!

I've never seen a direct comparison with under the scenario you have outlined, but CAVE cars have been on the dyno and produced between 178 and 181,

 

Where as CTHE produce around 193 stock. More than a difference to put if down to different rollers and conditions?

 

Sharkrider has owned a CAVE car and CTHE, he swears that his newer stock CTHE is just a quick as his old CAVE engine car running a TMC box. Read into that what you will.

The third post on this thread is a cthe with a bluespark fitted. Derek loves it!

I'm not debating they do or don't. I have a cthe, I would love it to produce more power. But realistically, unless you have both together in test conditions, results have to be taken with a big pinch of salt. I'm not a tuning expert but I have seen differant rollers and condition produce vastly different results on the same car.

I have run 50,000 miles in CAVE with TMC producing a RR'd 199bhp, and I have run 35,000 miles in a CTHE doing the same tracks ect ect , and they are as quick as each other... believe me I wouldn't have settled for a slower car, I would have HAD to do something! lol Isn't it this thread I posted me at castle coomb behind 2 mapped CAVE cars? sparklys was producing over 200bhp, and my CTHE had exactly the same acceleration on the straights. So from my point of view that makes it a fact. if his car had 20 bhp more, he would have been driving away. its a long straight !

 

ok... i retract the FACT thing until I get mine on a RR but if mine is producing 190+bhp, I wont be getting it mapped.

I'm skeptical that there is much difference between the two.

Have you driven a Run in CTHE? 

No but I've only drive a standard CAVE for a month or so, so I'd struggle to say.

 

I did find this post through which suggests it does.

I had my cthe on rollers and produced 181bhp so if mine supposedly could be producing 193 I'm way off and 207 ftlb torque

Hmm, good to get the input from a CTHE owner.

Very interesting! Maybe the myth isn't true...

Have to zoom in a bit but my cthe on rollers

Unfortunately I never had my car Dyno tested BEFORE fitting the Bluespark Box.

 

If CTHE engines produce in the region of 185-190 BHP as standard, then adding the Bluespark box hasn't increased it any, if at all.

 

However I know for certain sure that the car drives completely differently with the box than without it.  Mid range torque feels much livelier & it will hang onto higher gear ratios longer before changing down.

 

Really, at the end of the day squiggly lines on a graph don't particularly excite me. Knowing & feeling that my vRS is faster than standard does.

Love the jogging pants or are they shorts?

Myth busted!

 

Lets not hear any more of this rubbish :peek:

Annoyingly not, we need a CAVE car on the same rollers on the same/conditions to get a real idea.
