My turbo conversion has been Dyno'd @ THOR

Post by juliankv73 »

Hi Guys.

Ive just got back from Thor, what a pig of a journey home !

I have finally had my dyno test to see just what my car is capable of since having the Turbo conversion and recent new zorst!

According to Nod, Patrick & Matt @ Rogue systems my car was witnessed doing 301@ the hubs on their Dynamometer BUT at 1.0 bar! :wink:

=D> =D>

What ya think??

Looking at the Dyno, I am confused. What is the dyno reading at the wheels then??

i'm guessing a ct20b, looks like a rev3 swap and he doesnt mention an uprated turbo :-k

The 300.4 in the green box on image 2 is the HP at the hubs. Minus 5~10HP for the at-the-wheels figure depending on the size and weight of your wheels.

But at the top of the graph it says "At the fly" so doesn't that mean the 300.4 is at the flywheel? I have no experience in this but surely it would only be at the hubs if it said "at the hubs"???

Going from what little knowledge i have i would guess that the car is around 260-270 at the hubs and around 250-260 at the wheels depending on the size of them etc.

All Thors reading are at the hubs, take no notice of what it says on the sheet,

Hi guys,

Nod , Patrick and Matt were just as stumped at why my car was running with so much power!

It took Nod and hour and a half to get it running poperly coz the car was showing detonation (I never knew!) and running too lean! So it was F-Conv in- FConv out shake it all about, check inginition, timing etc etc etc

THEN found it was a faulty map sensor, Slapped on a new map sensor and the car just threw lots of power down!

Nod, Patrick & Matt were shocked at the power from it. It was Tony Guttmans old engine (TUR8O) so it was always a strong one, but not running at 1.0 bar and at 301 hubs!

The car is standard with no internal or turbo mods.

It has JUST apexi filter, New REV6 exhaust & REV 6 downpipe, AVCR, fidanza lightened flywheel, standard clutch and release bearing, standard gearbox etc.

The car has only ever been worked on by Rogue Systems, so all credit goes to them and of course Nod @ THOR for releasing all those bad boy horses and giving me this reading!

P.S Is there power loss from hubs and wheels figures?

Either way a lot better than my previous result and the birds nest flying out my ol' zorst! :oops:

MMMMM POWER!!!!! =D> =D> \:D/ \:D/ :tongue:

Standard everything else

New REV6 exhaust & REV 6 downpipe


Looking like these bits are part of the contribution to the power. Now I know the ambient temperature is generally responsible for the extra power hike, but I'm led to believed thors rollers are designed to accomodate with the temperature fluctuations ... but I guess you still can't beat a good cold charge for good power !

THEN found it was a faulty map sensor


I've nto seen that one before... these denso parts usually last longer than the cars life ! :eye:

You will lose a bit but not much. Raise your boost by .1 and you will have 300bhp at the wheels.

Seriously powerfull! Well done!

Cheers Scott! I am one happy Turbo owner! All the money I have spent these last few months have finally been worth it!

AHHH I almost forgot, in answer to JJ 's post, I DO have a charge cooler....THE PACE one!

Well there you go... !! Its a proven fact those act like fridges especially this time of year... no wonder you've that power ... torque will be special with the cold ! :wink:

As I had never driven a turbo before I got mine transplanted :oops: , I had never even known that my car was lacking in serious power!

I had a HKS zorst that was blocked, a faulty Map sensor, and the last time I was up to Rogue for my new REV 6 zorst, the car was running at .92bar! AND I was oblivious to it all ](*,) ](*,)

I cant say I am any more experienced in all this turbo stuff, but when I plant my foot down, it sure gives me a sweet feeling and almost makes me wanna pee myself 8-[

Im defintely gonna start trying to read up on this technical "turbo" malarky sop I can better understand my car! O:)

.......I also for got to say that my car is de-catted and was running on about a third Tesco 99 RON fuel (already in the car!) and I filled up further on Shell optimax before I made the trip up to Coventry!

HTH :wink:

that sounds just like the same spec as "dangerous" had at this rolling road day,

He also said he saw 300rwhp at thor's dyno, but couldn't managed 300bhp fly on this one.

Just out of interest how accurate is thor's dyno? i mean ever car i see put on there rollers always comes up with a very high power figure compaired to when the same car is dyno'd elsewhere. :?

Well TBH Ive not seen many dyno's!

The last dyno my car was on was at the Dyno day organised by Frank, and my car performed like cr@p for all the reasons I said earlier.

With Thor's one, your wheels are off, their *splined hub adaptor* is bolted to yours and then the splined hub (like on the old wire wheel hubs on classic cars) is then inserted into their dynomometer (also with splines to receive it.

This is then rigged upto a computer and then presto...

Its supposed to be dead balls accurate as their is no slippage from tyres on rollers and the computer measures accurately all the timings etc. No flywheel figures, just hubs :wink:

i know how there dyno works :D

Just wandering because there is also alot of variation from one dyno to theres, the ones at this rolling road day were all consistant so i wouldn't say it was wheelspin being a problem, Although they did have a problem to start with until the guy strapped it down properly.

Not accusing them of anything, just a little confused.

Sorry m8 :oops: . The only thing I can think of is the cooling.

The unit they have seems to be only 7ft high!

They put a fan at the front, rear and sides of the of the car.

The last RR day I went to, they had a "pipe" fan which was **directed** by operatives to the IC or CC and one fan at the front, but it was in a large garage.

Whether this affects the results I dont know being a novice to all things MR2 turbo :wink:

A true test would be to dyno my car elsewhere and to compare results perhaps??!! But at the moment i'm just way more happier knowing my car is producing a bit more than the 177RWHP I had at my first and prior rr result! \:D/

yeah would be interesting to see how much difference they make,

Could do with getting a car to try a few rolling road days with an intake temp gauge in the throttle body to see how much difference the cooling fans make.

If you would care to read the thread that Nod posted about last sundays rolling road i'm sure it will enlighten you more on the topic of the rolling road day... As I'm sure we actually agreed in conversation while the dyno operater was dyno'ing your lesser powered car (the red one with trust side skirts)we both agreed that it looked like he was letting off the throttle as the rollers started to lose grip.

Dynapack dynamometers are acrurate to within 0.01 hp thats why people like the The williams F1 team and the 5th gear T.V show use thors dyno.(if you dont believe me look on thier website !)
