just fitted gt28 twin turbos

ok guys after much thought (two seconds) i thought ok lets give it a try so i purchsed a set of gt 28 turbos from the states, fitted them with a lot of swearing getting the old one's off.

once fitted i took the car to ryan g at srr where he installed a syvecs ecu and set the car up on the dyno after a few problems we got it sorted and manged too get 472 bhp before the my stock uk injectors where running out of fuel so we had to turn it down 428bhp for a bit for safety till i upgrade the injectors and fuel pump but ryan assure's me we should pass the 500 bhp mark. below the dyno graph so far you will see it come's on power pretty quick.

UPDATED PROGRESS

this is the the graph from the second dyno trip but now fitted with bigger injectors and running at 1.2 bar getting close to that magic 500 mark now need to fit water injection and 264 cams then i should be able to up the boost to 1.7 bar

So you have put on a set of hybrids?

Dyno graph?

not really no

how do i upload pics?

how much did the turbos set you back mate ?

they cost me about $3300 just the turbos

Id love to see pictures.

Which turbo manifolds did you use?

Im guessing you went with gt2860s?

not really no

how do i upload pics?

They aren't hybrids? Are you sure? Sounds like the stock turbos with GT28 internals in their place?

Cracking results if that is the case, look forward to the graph and further performance gains

not really no

how do i upload pics?

Upload them onto an external site ie photobucket, then host them on here using the links provided.

i have a dyno graph if some one can explain how to post it as it keeps failing

ok thanks

not really no

how do i upload pics?

Click "Go Advanced"

Click "Manage attachments"

Click "Browse" and point to the photo you want to upload.

Click "Upload" to upload the photo to the site.

Close the external window

Type what you want to type then click "Submit reply"

Job done

Hmmm i was hoping you'd say they were cheaper. What else did you need to buy, a manifold, or were they bolt on??

These at a guess?

If Jamie is correct then the clue is in the title as to whether they are hybrids or not bud

Interesting to see the dyno graph to see what power delivery is like.

How much boost were you running?

Not on an otherwise stock car though, at least I wouldn't think so.

Auto with high stall, decent drag suspension and decent drag tyres at a guess. That plus having the turbo's give one big run on US fuel.

It isn't that hard to believe.

Hell BPU supras can run 11s on drag rads with a good driver.

Genuine GT28R would require a purpose made manifold, and down pipes, they will also not be sequential, good result although, an single BB GT28 on its own is good for 350BHP, pic would be good, you can also upload pics to Photobucket and then use the image code in between these tags, image

Also GT28R turbines Will not fit in the std turbo casings, the R also designated ball bearing, which will also not fit in the std core.

ok dyno graph up in january i will be fitting 650cc injectors water injection and bosch fuel pump then we will wind it up

Sounds good, interested to see what they will do.

Well if you put it like that then it is more believable, though still an astonishing time for a sub 500bhp car.

If you cant get the pics to work, send them to one of us (pm for an email address) and we'll host them for you Look forward to seeing the results

They claim 550 RWHP in the advert.
