Assuming the engine is up to it,what,s the most anybody has seen from one of these turbos,cheers.

 

I was under the impression that these are upto 500bhp jobs(?). No?

 

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.....

 

Impressive!

 

thanks for that,Andy

 

Ellie !

 

is that on 2litre?

 

Hi Dunx

Its on a 2.5l car with Cosworth heads

 

Its on Shaun's high compression engine so it will take some beating! My turbo is an AET drop in GT30 and is making 440bhp at 1.7 bar on a 2litre, dont want to bore everyone with the graph but it is in my profile under pics

Banny

 

Hi chuck, I'd be worried if someone thought you were a bloke

LOL

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.

 

When did your car make 556bhp ???? I must of missed that one!

 

Great results there your bound to be over the moon with that.

 

Estimate based on the "high boost" hub figure adding 15% transmission losses I suspect.

 

I would say it would not be very far away from that

 

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.

 

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?

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.

 

Jesus H Christ!

You will need to speak to Andy Taylor at AET for that info, as I don't know the AET Turbo catalogue back to front.

 

LOL sorry - I assumed you knew, seeing as you love your obrut so much!

I'll go and peruse their site, see what I can glean...

 

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.

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.

Banny

 

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

 

That is my 2.5 car, which was running the MD321T+

And this is what the MD321T+ has been replaced by



Banny

 

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).

 

Yes two cars Joz lol the 2.5 with the rotated turbo is now in a newage sti and the 2 litre GT30 (soon to be a 2.3 and a rotated GT30R) is in the classic. Hope that makes things a little clearer

Banny

 

My AET GT3071 53R standard fit in a 2.5 classic is running 456.4bhp and 490lbft at 1.8bar peak dropping to 1.6bar

 

Sure, got it now!

What's the current rotated jobbie on your 2.5 New Age STi, then? What's that producing too, etc...?

 

It is a GT35/42R (0.82 a/r) will be running a safe 570/580bhp but turbo is capable of 600bhp+.

Banny

 

Ch**st!
