Luxluc Posted December 26, 2013 Author Share Posted December 26, 2013 You guys are crazy talking about 8-900hp as if its like 200hp lol Luc what power did you make on the hub dyno with your 66mm turbo also what a.r is it. I have got similar spec to you but 67mm billet .81 turbo. I think my exhaust housing is too small though. It pushed 747 at the hubs at 1.5 bar of boost. The BL366 turbo was maxed out at that boost. It's a divided 0.91 AR that I have. Quote Link to comment Share on other sites More sharing options...
Luxluc Posted December 26, 2013 Author Share Posted December 26, 2013 I did some research. I'm pending between the 2 CEA Precision turbos : - The 6766 with 1.15 AR - The 6870 The 6766 is rated 935 bhp, whereas the very new 6870 is rated 1025 bhp. I'm waiting for the tests in the US by SP to see what they take out of the new 6870 unit, as I want to see how fast it is spooling. I'm not convinced about the ethanol setup. I know that I won't be using it really over here, as its a lot easier to fill up with V-Power. Plus, after chatting with Ryan, 15% power increase is to be expected with an 50% ethanol mix .... which means 1000+rhhp on a RWD car. I think that won't be really streetable any more. I defo want between 850-900 at the hubs, but no 1100bhp monster. What do you think? Quote Link to comment Share on other sites More sharing options...
Parry_10 Posted December 26, 2013 Share Posted December 26, 2013 It pushed 747 at the hubs at 1.5 bar of boost. The BL366 turbo was maxed out at that boost. It's a divided 0.91 AR that I have. That's a big difference compared to my 67mm with .81 AR mine made 618 at 1.5 bar. When yours is at lees for the turbo change id be interested in buying your turbo and having lee put it on mine.

Luxluc Posted December 26, 2013 Author Share Posted December 26, 2013 No problem mate. My turbo only ran around 2500mls, of which around 1000 mls of running in the engine. I will give a shout around April mate. If you want a spin in it, we can meet at Lee's when I come up Quote Link to comment Share on other sites More sharing options...

Luxluc Posted December 26, 2013 Author Share Posted December 26, 2013 Don't get me wrong on it ... my Supra is really fast with those 750 at the hubs throught the BL366 unit ... but I need that little more to respect the stickers Jamie put on my car :d Quote Link to comment Share on other sites More sharing options...
Luxluc Posted January 10, 2014 Author Share Posted January 10, 2014 I've got some feedback from SP. They haven't tried the new 8670 turbo yet. There will certainly be a difference in spool and power output between the 6766 and 6870 turbos. PTE wanted to design this turbo to bridge the gap between the existing 66mm and 75mm turbine wheels. The new CEA Gen2 technology is promising though. Spool is an important factor for my decision. The 6766 should spool slightly better than my current unit (BL366), which already is very responsive. The only person who has used the 67mm and 75mm (7175) turbo is Jamie. Jamie confirmed that the 7175 was too laggy on his setup (the same I have). @Jamie : Spool in between the 67mm and 7175 ... would that be reasonable for the ultimate street setup Any comments are welcome guys Quote Link to comment Share on other sites More sharing options...
Noz Posted January 10, 2014 Share Posted January 10, 2014 I defo want between 850-900 at the hubs, but no 1100bhp monster. Surely 900 at the hubs isn't that far away from 1100bhp? Quote Link to comment Share on other sites More sharing options...
Sukhy Posted January 10, 2014 Share Posted January 10, 2014 Luc I thought the BL366R is rated to 900 at the fly so with your results of 747 at the hubs is about on par isn't it. I just thought because I'm sure I've read you are reverting away from the BL366R because it does not meet the power rating of 900hp advertised by Boost lab.

JamieP Posted January 10, 2014 Share Posted January 10, 2014 If it was me, I'd go 6766, keep the fast spool. Quote Link to comment Share on other sites More sharing options...
Kaan W Posted January 10, 2014 Share Posted January 10, 2014 When did you hit full boost with the 75 Jamie? Quote Link to comment Share on other sites More sharing options...
JamieP Posted January 10, 2014 Share Posted January 10, 2014 As with any turbo, it's different in every gear. It was laggy, my big GT42-76 spooled faster. Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted January 10, 2014 Share Posted January 10, 2014 If it was me, I'd go 6766, keep the fast spool. Personally for me, The 6766 is the perfect street turbo. Full boost by 4K and still capable of handling 900bhp! Quote Link to comment Share on other sites More sharing options...

Luxluc Posted January 10, 2014 Author Share Posted January 10, 2014 Cheers for the input guys. You confirmed my thought Jamie : I have the 6766 1.00 AR on the top of my list. Quote Link to comment Share on other sites More sharing options...
Luxluc Posted January 10, 2014 Author Share Posted January 10, 2014 Interesting to know Your 3.4 with a 6766 would make crazy power...a guy in the states runs that combo and pushed 950rwhp. Quote Link to comment Share on other sites More sharing options...
Kaan W Posted January 10, 2014 Share Posted January 10, 2014 Your 3.4 with a 6766 would make crazy power...a guy in the states runs that combo and pushed 950rwhp. It would make for an exciting powerband also I've also seen someone making 850rwhp on a 3.4 with a 6266. I wouldnt mind the 7175 though as the autobox pretty much keeps revs in the powerband once moving. All of them are good turbos it's hard to decide lol.

Steve Posted January 11, 2014 Share Posted January 11, 2014 It pushed 747 at the hubs at 1.5 bar of boost. The BL366 turbo was maxed out at that boost. It's a divided 0.91 AR that I have. I know mine was a brand new unit compared to yours, but I thought that the upgrade to the Billet wheel was the same thing with the older type?

Luxluc Posted January 11, 2014 Author Share Posted January 11, 2014 (edited) I know mine was a brand new unit compared to yours, but I thought that the upgrade to the Billet wheel was the same thing with the older type? I know Steve. Your new BL366 pushed considerably more than my converted 91-79 unit. Nevertheless ... I never kept my turbo longer than one and a half year so far. Time for a change. The guys at SP (US) compared the BL vs Precision CEA units. The 6766 spooled faster and pushed 60-70 bhp and 50 tq more than the BL366. Ryan also praised those new CEA turbos. I will give it a try. The only concern I have that I will have traction problems in 3rd even on the semi-slick tires. I plan to upgrade the rears to 305 / 315 width (maybe go down to 18"). In combination with the Michelin Pilot Cup tires, this should give traction even in 2nd gear when properly warmed up Edited January 16, 2014 by Luxluc (see edit history) Quote Link to comment Share on other sites More sharing options...

Luxluc Posted January 11, 2014 Author Share Posted January 11, 2014 I was thinking about going 18" Jamie. The classics look nice, as well as the 505 or Sp500. Still slightly undecided about the rim type though. I will ask for advice when time has come. Quote Link to comment Share on other sites More sharing options...
Luxluc Posted January 11, 2014 Author Share Posted January 11, 2014 Surely 900 at the hubs isn't that far away from 1100bhp? Mine pushed 750 at the hubs mate. I'm not convinced that this figure equals to 875 at the flwheel (taking the 17.5% transmission loss into the calculation). All those discussions about conversions don't interest me. Mine should be 800+bhp now, the exact number is only speculation. I want a fast spooling turbo that pushes between 850-900 at the hubs. This should give me a 900+bhp Supra. A 900 bhp looks like this: Mine ain't that fast for the moment ... not yet :d Quote Link to comment Share on other sites More sharing options...
