Anyone else have these turbo\'s?

If so what sort of power are you seeing from them etc

cheers

John

[Rixio]

Yes...but iv never had it dyno\'d...yet...rough guess mid 300\'s...much more progressive power over stock you can really feel the build up...

Are you running a stock engine etc?
What mods you running?

Rixio :Thumbs-up

[John_Hudson]

I have an apexi GT FMIC, apexi power fc, apexi intake, koyo alloy rad, greddy profec b spec 2 boost controller, sard FPR, will have 850 primarys installed on the primary at the same time as the tubs, uprated fuel pump, greddy 80 mm DP, 3" mongoose decat exhaust system. theres other stuff but its more suspension braking related etc.

Hopefully the turbos are already converted to non sequential, im told they look like they are from the pics so will see, if not they soon will be

And the block is stock port

[Rixio]

With stock ports and those mods you should be pushing 300rwhp +/- 20hp unless you go really silly with boost!

You are really retricting yourself with not porting...whos doing the work??

[John_Hudson]

Ive installed most of it myself but Trex said he\'d give me a hand with the turbo\'s

[Rixio]

Ah good man is our dom...good luck with it, but as i said without porting i dont think it will make higher than 300ish

HTH

I know of people running more power through stock turbos but ovbiously they havnt lived very long.

Im hoping for the same effect but at a safer boost level.  After reading what peole have said on rx7club.com they are good for 415 FWHP at 1 bar which is more than enough for me, however a street port is on the cards anyway but not anytime soon.

Its work in progress

[Rixio]

Yes, but those people pushing that power through stock twins, only got there with some sort of ports and alot of other work...

340rwhp i a good possibility...but porting is a major factor to make it...
I.E:
Myself 320rwhp maxxing stock injectors at 5300 rpm on stock turbos still having more power to come...now has other twins installed
Strange Days blew his after 2 or 3 weeks iirc he made 320rwhp @ 1 bar
John (Warthog) to get 380 ran full RE Engine with big port and alot of other mods
John Yorke not 100% on mods but he also ran/runs RE internals with large ports
Shaun has been running 320wrhp safely for 2 years and is the only one i know that hasnt had any problems with it...(But he drives like a pansy :p)
Even Dom with his mid 300\'s has uprated turbos + porting

Now running 3 cars with uprated twins i know what comes with the territory

I wish you every luck in the world and im not trying to put you down...but with stock ports i feel without big boost you wont make 340wrhp. Maybe a tuner can enlighten us with their knowledge...

If you do make it, then thats fantastic and i await the results...

[John_Hudson]

its cool, i dont feel your putting me down, its nice to have a conversation about possible power outputs i\'ll keep an update going if your interested in my progress

John (Warthog) to get 380 ran full RE Engine with big port and alot of other mods


Ref above mate, the engine was an REW with only the runners polished and mild exhaust porting--plus lots of other mods.. HTH.:wiggle

[BlitzBoy]

Sdminus with WI on stock ports and twins posted terminals of 115mph this indicates power in the region of 360+ rwhp approx 1BAR.
Its all in the tuning

[John_Hudson]

Nice one cheers dude

I thought you had cosmo internals? Which is what i meant...Hehe you know what i meant though john...:spank

Mark - Scots car was specifically setup for the strip though...wasnt it??:3Confused

I went through the trap at RSIII at 13 dead with 112mph @ 0.6 bar! With only 316rwhp at 1bar...

Rixio :Thumbs-up

[Warthog]

Rixio, that was the old engine. The RE is my set up now.HTH.

[BlitzBoy]

Scot actually ran a 117mph terminal in the end with consistant 115mph, remember terminal speeds come down if ya car really hooks up on the track and you get a faster time.

When I was running on low boost 10psi on my white car I was running 115mph terminals and my car dynoed at 357rwhp at that boost pressure, remember dynos are only a tuning tool and bragging pub talk which im a member of :rollin

So I think im quite safe in saying Scott was running at least 350-360 at the wheels with the terminal of 117mph
