Our largest GT30 drop in hybrid is doing:
486 WHP - this is wheel horse power, fly is approx 556HP
512 WFt/Lb - again this is torque @ the wheels.
Results are @ 2.0bar peak and 1.8bar held
Also 480Ft/lb of torque is being made @ 3500rpm - now beat that.....

andy1066,
I am the fortunate chap that the above figures are associated with.
Feel free to have a look at the Project Thread on my car for information on specifics: https://www.scoobynet.com/projects-4...oject-car.html
It is a 2.5ltr high compression, blue printed engine, with the AET GT30 drop in turbo.
At low boost it achieved 415bhp at the hubs and 485bhp at the fly (1.5bar on VPower only)
At high boost it achieved 485bhp at the hubs (2bar peak, 1.8bar held on VPower only). It is well over 500bhp at the fly on high boost
I am over the moon with the performance of the AET turbo.
Banny's GT30 will not be the same spec as mine, so bear that in mind, as AET have three (I think) sizes in that range. My current turbo is the largest/latest spec GT30 Hybrid they produce.

Neil.P1,
It is nice to have, but has cost me a lot of cash and many peoples time to get there!
The car came 4th overall at the last round of the ScoobySprint Championship..... on low boost! We tried High Boost for one run, but the car was way to lairy on the handling circuit as the suspension / geometry was all to ****. Would of, could of, should of!
Onwards and hopefully upwards.

Is this 440bhp on V-Power only? Do you reckon this GT30 will do 400bhp on 97 RON only?
How does it compare with the MD321T / S206 / HS420 in terms of spool-up times and thrust to the redline, etc. How much boost can it take within its efficiency range, and how does this compare to the other 3 turbos mentioned above?
Lots of questions for you to get your gnawy teeth into! LOL

Yes... standard position and same pipework as OE (if it is a single scroll car).
ALL of these figures I have given on this thread are using VPower only.
Normal Super Unleaded figures would be less I suspect, but not by a fat lot. I would expect a 40bhp drop if I was mapping for 95.
Since my engine spec is quite different to most, it would not be entirely fair to compare against any other engines in reality. Unless I tested all the other turbo's on my engine, you would never know for sure. Spool up is very good though on my set-up. IIRC when I ran at the last Zen Rolling Road Shootout (with my previous engine set-up, which was not as good as the current one), no other graph gave the lowdown grunt that mine had, together with the top end bhp.
I have ran this turbo up to 2.5bar before on my previous engine..... unfortunately my heads decided to lift! The turbo will run more than my current high boost setting of 2bar peak, but I am not interested in screwing the **** out of it, especially as I have a newly built engine. With the figures attained now, there is simply no need to.

Thanks Shaun.
Can you divulge further details of these 3 different variants of the GT30, and their power levels/max boost/spool up times, etc...?
Thanks.

By "drop-in" I assume you mean its a OEM std position jobbie i.e. non-twisted, non-rotated, etc.?
Is this 440bhp on V-Power only? Do you reckon this GT30 will do 400bhp on 97 RON only?
How does it compare with the MD321T / S206 / HS420 in terms of spool-up times and thrust to the redline, etc. How much boost can it take within its efficiency range, and how does this compare to the other 3 turbos mentioned above?

Joz sorry for the reply not been on since yesterday afternoon. Yes it is a OEM standard position turbo and it made the 440bhp on V-Power mapped by Simon on Surrey Rolling Road.
I think you would have a pretty good chance of making 400bhp on 97ron with the turbo. It is very similar to the MD321T according to Simon when he mapped the car and responds very similar.
Power Graph
Boost Graph
Everything happens about 300rpm sooner on the road compared to the graph, I will let you make you own judgements on how it fairs against the other 3 turbos as there is plenty of graphs floating about.

Cheers banny.
I'm curious... back in November you were running a 321T and 473bhp!
See post #50 of this thread:-
https://www.scoobynet.com/general-te...-please-2.html
How come you've gone over to the GT30, when the 321T seemed to do a similar job?
... Nay, you're now producing 'only' 440 on the GT30

Oh, have you got a 2.0L now then.... and the GT30 is more suited to a 2.0 than a 321T, hence the swap?
Or do you have 2 cars: one with a 2.5 and one with a 2.0?
Sorry but it's still not clear (I'm not [too] thick... honestly).
