hi geoff,
Man that picture looks GREAT!! ... just wondering though .. just turbo was pictured in that photo showing the space?

 

1. WOW! This manifold will clear the GT4094R?

2. Is that an Evo 7 PWR radiator? Seems like the upper radiator hose isn't in it's stock location.

Geoff, is the turbonetics F1 stuff oil cooled or is it a non-ball bearing turbo? If it is BB, I presume they have gone over to metal or high temperature composite retainers instead of what Garret uses in their standard GT turbochargers? Are they (Turbonetics) still using their semi-floating ball bearing system or have they switched over to the Garret like full-floating bearing to help reduce vibration damage? Can you get those F1 turbos without the Bullet Nut? Looks like interesting stuff.

Oh, just a side comment on the T67 being a GT series turbo. According to Limit Engineering (A Garrett Direct Distributor) the T67 is a GT series wheel. I also have the engineering compressor flow map for it and it shows a test date of 1997 and a BCI-8D notation, which I believe is a GT series wheel. It also has the basic blade profile of a GT series wheel. The only thing that doesn't match the typical GT stuff (just by looking) seems to be the high trim number. Even then, it is notated as a 61/63 trim, which makes me wonder if it is an "extended tip" type compressor? I've never paid attention to that...

One last thing of random compressor observation. The T04E 50-trim that performs the best is a BCI-18C wheel. The modern day 50-trim wheel also seems to be a GT series wheel. Makes sense though because the 50-trim T04E wheels kills every other T04E wheel available.

 

geoff, great work mate! the maifold looks amazing.

quick question though, what are the runner lengths like on that manifold?? are they close to being equal?? its look like a night mear to make! you cant even see the turbo! lol

have you any more pics on or off the car????

thanks Chris.

 

FYI, our stock turbo's are oil-cooled and they are stardard journal bearing turbo's, not BB. A turbo does not have to be ball-bearing for it to be oil-cooled...

 

Geoff i am not worried about the space because i had a smaller radiator in mine.Do you do a manifold for the Gt4088 Twin scroll for out right performance?or have you just designed one to fit behind the standard radiator?

 

I like my full race single scroll gt3037 kit!

 

Well....waddaya think so far? I noticed you are still using the MAF and don't have their intercooler piping in. Did you get a different kit?

 

I'm pretty sure it sort of did a build it yourself kit.

how much are you putting down? just reflash? supporting mods too please =D

 

The setup includes:

full race manifold
44mm wastegate
full race dumptube
full race 3" downpipe
Gt3037
custom licp
stock intercooler
stock uicp
force performance 4" intake

The setup is awesome once i tuned it correctly.. boost starts around 3k. I have not dynoed it yet.

Ill try to at least get a dataloglab file tonight or tomorrow.

comparing it to the TBE e85 setup i had running 330whp, it feels alot more aggressive.

 

this manifold IS designed for outright performance. We were not willing to make any performance compromises in the manifold. The downpipe is where the compromise for fitment lies. This allows our customers to tailor their setups by only changing out the downpipe. There are two options if you want even more performance from a 40R

1) If you want to use a Full-length radiator and dont need AC, you can use our Non-AC downpipe.

2) If you want to keep AC and arent using a full length rad, you can use our 42R manifold (available in 6-8 weeks). This will allow you to use a 4" downpipe, and 4" exhaust

Garrett simple does not have any possible way to make a twinscroll 35R. They used to, but no longer

Turbonetics realized this and developed the F1-35R for exactly this reason.

This picture shows one of the ultra-rare Garrett T4 Twinscroll 35Rs next to a Turbonetics F1-35R



that turbo is a T3 twinscroll GT3076R. The 40R has just as much clearance


1) yes it will fit a GT4094R with no problem -- AC, full length radiator, power steering, etc.

2) the F1 turbos are oil and water cooled. They are available in ball bearing and non ball bearing, and with or without the bullet nut

3) The 67 is definately not a GT wheel. I have seen the same compressor map as you (the garrett guys sent it to me) and its total BS. it says that its a BCI-18 but if you look closely it shows the exducer to be 81.5 mm, not the 84mm it actually measures out to be. I have no idea what that map is for, but its not the 67. The real compressor map is here:



are you sure? A T04E by definition is a T04E... not a BCI?

the reason the 50 trim kills every other T04E, is that its BIGGER!!

thanks alot for the compliments. i dont mind sharing details, but i would rather not go into specifcs on the manifold on a public forum, for obvious reasons. i can tell you it is designed very well, and based off of everything we know and have learned in the last few years. I am confident that the runner design isnt going to get any better design than what we have come up with. If you are looking for some pics off the car, here are a couple from our website:








nice install jordo. glad to hear things ended up working out for you!

jordo is using our manifold, turbo, downpipe,wastegate setup with a stock intercooler, MAF and stock coldside charge pipe. He got a great deal on a used pieced-together kit from evoM member ray raulston

 

If twin-scroll is so desirable, why has Garrett left a huge gap in their line of turbos for a twin scroll 600 hp turbo?

 

Becuase the market was happy paying top dollar for cheaper easier to design and comapaired to the competition better performing 35R's.... or the 40Rs.

When I mentioned not done sooner, I was refering to the Twin Scroll setup.

With the Above two GT35R's, which is better in terms of power and which in terms of spool? I am assuming that the left is the Garrett T4 and the right the Turbonetics F1-35R?

How would a GT35R react with a twin scroll setup Vs. a traditonal manifold? I would love to have a 35R with this maniold and now MIVEC it would hopefully make even more of a difference.

 

But if twin-scroll is so much cheaper and easier to build, why are the GT3071 and GT3076 twin scroll? Or am I wrong and they are single scroll?

 

am i right in assuming the stock turbo on evo's are twin scroll?
