Luxluc Posted November 15, 2011 Share Posted November 15, 2011 Hey Glenn, any plans for winter upgrades mate? Cheers Luc Quote Link to comment Share on other sites More sharing options...
Luxluc Posted November 15, 2011 Share Posted November 15, 2011 Luxluc made 625hp but not sure on the boost I made 626bhp (531 rwhp) @ 1.5 bar with stock intake and head. Early this year, it pushed 767 (651 rwhp) @ 1.8 bar with GReddy intake, 264 cams and stock head. Quote Link to comment Share on other sites More sharing options...
GlennK Posted November 15, 2011 Author Share Posted November 15, 2011 Luc, the top priority is to remove the gas flow restrictions from the inlet side and the exhaust side. So a big plenum and TB and a 4" straight through exhaust are required. I might also consider a bigger turbo with 4" V band...

mark newman Posted November 15, 2011 Share Posted November 15, 2011 Gleen What was the best bhp you got from your setup as it about the same as my old setup. Quote Link to comment Share on other sites More sharing options...
GlennK Posted November 15, 2011 Author Share Posted November 15, 2011 Mark, as per my Dynapack post: At 1.2bar: Hub Torque total = 1694 = rhtq of 1694/3.77= 449ftlbs (DIN) Then the calculated rwhp is = 461hp (reduced by the drivetrain losses)** And the calculated fwhp (assuming 20% auto losses) = 553hp** At 1.9bar: Hub Torque total = 1990 = rhtq of 1990/3.77= 528ftlbs (DIN) Then the calculated rwhp is = 541hp (reduced by the drivetrain losses) And the calculated fwhp (assuming 20% auto losses) = 649hp Quote Link to comment Share on other sites More sharing options...
Luxluc Posted November 16, 2011 Share Posted November 16, 2011 541 rwhp sounds fine for the setup. I remember that the stock manif was restrictive on my setup. My Supra pushed (with the BW 91-79 unit) 603 bhp @ 1.3 bar and 626 @ 1.5 bar with the stock intake and 264 cams. With the GReddy intake installed, the power was over 700 bhp @ 1.5 bar, and 767 @ 1.8 bar. I guess you will see nice inprovements with a new plenum .. I was impressed by the difference it made. Cheers Luc P.S. I'm still on a 3" DP/MP combo for the moment, so not that restrictive on the current power setup. Quote Link to comment Share on other sites More sharing options...
Steve Posted November 16, 2011 Share Posted November 16, 2011 What makes you think the stock inlet manifold/throttle body is causing a restriction on your setups? I agree an aftermarket plenum/throttle body will improve things but I wouldnt say the stock manifold is a restriction at these power levels. Mine is still happy with the stock inlet/throttle, in fact my turbo is maxxed out not the inlet. Quote Link to comment Share on other sites More sharing options...
Luxluc Posted November 16, 2011 Share Posted November 16, 2011 When we mapped my Supra back last year on the stock intake, we wouldn't have gained much more with the 91-79 turbo by going up to 1.8+ bar. Ryan suggested to go for an aftermarked plenum for the next power step. After the installation of the GReddy intake, power seemed to raise even more at higher boost settings (although 1.8 ain't really high).

Rob_Mitchell Posted November 16, 2011 Share Posted November 16, 2011 Is this all on boostlogic box too? Dont seem a bad result in my eyes. aftermarket manifold would make a difference but i cant see why the stock manifold is a resriction at the power level your at now Quote Link to comment Share on other sites More sharing options...

Luxluc Posted November 16, 2011 Share Posted November 16, 2011 Hehe. Glenn likes being shifted (auto)...I do it myself (manual) Quote Link to comment Share on other sites More sharing options...
GlennK Posted November 16, 2011 Author Share Posted November 16, 2011 Yeah. Luc does it himself....Me, I like to sit back and get it done for me ;-)) Seriously, I don't understand why I can't push 800+hp through an (uprated e.g. ML Boostlogic) autobox. There's supercars around that's handle that - and I don't mean on a US 2 shift Powerglide either. How does a Lambo or a GTR or a Porsche handle that power? I know Jamesy has bailed out and going 6 shift manual. I will never say never in the pursuit of a nippy performance on Track or private road..... A big TB and plenum give the 'compressed' air someplace to vent in a balanced and efficient way into the engine. The bigger the boost the bigger the squeeze and restriction you are going to experience. Logically, you've got to vent that volume out as fast as you are pushing it in. So a big bore exhaust without any bends/cats in it is what's needed. And that's exactly what was observed at the Abbeywood Dyno runs...a bit of 'blowback' as the engine tried to do balloon impressions. So no point in running 1.9b as it's no good with my current setup. You can see my dyno numbers and the difference is not worth the engine stress :-( But next Spring - I hope to have the system setup to handle the next power level I'm after - 750-850 hp.

Luxluc Posted November 16, 2011 Share Posted November 16, 2011 Nice explanation Glenn. Are you sticking to the turbo, or are you going bigger. I'm gonna have my engine forged, with race head and cams, and more boost. I'm eager to see how close I can get the 91-79 tubbie to 850 bhp.

GlennK Posted September 2, 2012 Author Share Posted September 2, 2012 Just got my car back from Lee's this afternoon. Lovely growling tone to it now...Had a new SRD chrome plenum fitted and a 4" HKS catback. That should sort it out now. Now booked into SRR 10th September for its remap. Can't wait...

GlennK Posted September 3, 2012 Author Share Posted September 3, 2012 Had it at 1.9bar on top setting!! Regular is at 1.4bar. So probably not much room to go higher with that setup Quote Link to comment Share on other sites More sharing options...
Luxluc Posted September 3, 2012 Share Posted September 3, 2012 1.9 is a lot. I want to see how far the BW 366 can be pushed ... I want to break Mark's (Newman) record of 797 rhhp (without nitrous). I don't know what max boost can be .. hopefully 2.2+ bar Quote Link to comment Share on other sites More sharing options...
GlennK Posted September 3, 2012 Author Share Posted September 3, 2012 797 rhhp!! What boost was that at? And when are you going for the record then? Quote Link to comment Share on other sites More sharing options...
Luxluc Posted September 3, 2012 Share Posted September 3, 2012 I think that was at 2 bar Glenn. Mark has a fully built engine with stage 4 head (if I remember right), and 280 cams. I have all the parts for the engine build at mine so far (JamieP's head with 280 cams, Carillo Heavy Duty rods, Mahle pistons, Syvecs ECU, ID2000, RPS triple carbon clutch, etc). Darren at Whifbitz will start beginning of next year with the engine build, and then I want to see what max I can get out of the S366 tubbie. I don't want a monster turbo, but something still streetable that makes full boost at 4k, but delivers 800 rhhp. Quote Link to comment Share on other sites More sharing options...
mark newman Posted September 3, 2012 Share Posted September 3, 2012 1.9 bar power was droping of after that. Quote Link to comment Share on other sites More sharing options...
