TurboNova Posted October 24, 2012 Report Share Posted October 24, 2012 Im sure once the details come out it will be a nice engine. however Im not sure about going back to an "Lt1" is the way to go. With as much success the Gen 3-Gen 4 LS motors had you would think it would be bad luck to rename the next gen an LT1. http://www.detroitnews.com/article/20121024/AUTO0103/210240387/1361/GM-unveils-small-block--LT1-6.2-liter-V-8-engine-for-%E2%80%9914-Chevrolet-Corvette Quote Link to comment Share on other sites More sharing options...

ForeverMaker Posted October 24, 2012 Report Share Posted October 24, 2012 We can call the engine anything we want in the world. The possibilities are endless. Oh I know, LT1 ! Quote Link to comment Share on other sites More sharing options...

Mallard Posted October 24, 2012 Report Share Posted October 24, 2012 GM had a presentation this morning on all the details. Check Autoblog for the goods. DI 450/450 cylinder activation continuously variable cam timing claimed to be the most advanced combustion cycle ever etc. Quote Link to comment Share on other sites More sharing options...
JuicedH22 Posted October 24, 2012 Report Share Posted October 24, 2012 that is dumb to recycle a name like that! This isnt the first time, and the LT1 of the 90s was a recycling of the HIGHLY successful and popular LT1 of the 70s.... GEN1 = SBC (might as well be ls1, lol) GEN2 = LT1 GEN3 = LS1 GEN4 = LS3 GEN5 = LT1 and thats just generation of small block V8... They had the LS1 big block in several 1969 models, big block LS6 in the early 70s in vettes and chevelles, and the 454 LS7 in the 70s.... then like I said the LT1 in the stingray corvettes, and now back again. Its no shocker they are also calling this corvette the StingRay again. Quote Link to comment Share on other sites More sharing options...
JuicedH22 Posted October 24, 2012 Report Share Posted October 24, 2012 Other thoughts... 1) Direct injection, you had to see this coming, its a huge improvement in combustion efficiency, which should correlate to more TQ at the engine. (since TQ is directly proportional to VE) 2) 11.5:1 CR, also good for more power, goes right along with DI. 3)square ports, this is the ideal shape for an intake port for the most part, glad to see it implemented. 4) If the LT1 is back for the base model... what are the chances of a return for the LT5 with DOHC? (crazy I know!) 5) I am interested in tuning capability. What the stock injectors can handle, and how long before upgrades to injectors and/or HP pumps are available. When/if EFI Live/HPT will have ecm tuning packages to consumers. Quote Link to comment Share on other sites More sharing options...

pontiacfreak142 Posted October 24, 2012 Report Share Posted October 24, 2012 with holding judgment till we see what it can do, but so far with all of the new technologies it has, its still a 6.2 that only makes 14 more hp than an LS3 and is more than likely gonna cost quite a bit more to mod, im unimpressed Quote Link to comment Share on other sites More sharing options...

wagner Posted October 25, 2012 Report Share Posted October 25, 2012 From what we heard at the LSX Shootout look for some cool stuff coming from GM at SEMA. Lot of talk about performance parts from the factory that will not void a warrenty. Quote Link to comment Share on other sites More sharing options...

Mallard Posted October 26, 2012 Report Share Posted October 26, 2012 DI I hope the aftermarket creates some fuel pumps that can keep up with TT applications I think there will be a bit of head room with the stock pump, if it's been designed anything like the turbo Ecotec. There are guys running double the stock power on the stock fuel system. This slide shows the injectors flow 22 cc/sec @ 10 Mpa, but the fuel system runs at 15Mpa. The pump pushes 1.48 cc/rev on a 3 lobe cam. http://www.autoblog.com/photos/lt1-gen-5-chevy-small-block-v8/med/#photo-5384611 There are aftermarket companies making upgraded pumps for DI systems. The guy I worked on my Solstice/Sky turbo kit with is actually making a system for the Audi RS4 now. Quote Link to comment Share on other sites More sharing options...
TurboNova Posted October 26, 2012 Author Report Share Posted October 26, 2012 I will never mod a new car now...its beyond stupid. Part prices will go up and supporting parts that would typically be fine with aftermarket items are now going to be pushed to their limits from the factory. Im not saying that im not a fan of innovation and future mpg/emissions that "perfromance cars" will be getting but its just going to get out of hand. I know im an Ls fan boy but its so simple and well built. I know what the old heads feel like, when you talk to them about when points and condensor ignition sytems went out and carbs went out.

NTHER91 Posted October 26, 2012 Report Share Posted October 26, 2012 DI I hope the aftermarket creates some fuel pumps that can keep up with TT applications This made me lol The reason being you work for an aftermarket company.. And by now they should be able to design a new pump. Man I'm glad I was overlooked... Quote Link to comment Share on other sites More sharing options...
351mach11647545510 Posted October 26, 2012 Report Share Posted October 26, 2012 I'm reading the stock pump should be able to support up to 700 horses Quote Link to comment Share on other sites More sharing options...
Mallard Posted October 26, 2012 Report Share Posted October 26, 2012 I'm reading the stock pump should be able to support up to 700 horses If the ZR1 is twin turbo you can bet it will support that with some headroom. Quote Link to comment Share on other sites More sharing options...
thorne Posted October 26, 2012 Report Share Posted October 26, 2012 The 3.6 DI camaro was unable to sustained FP on a 400whp application and atleast 1.5 years ago we didn't have any pump options. That's all I'm saying Otherwise I welcome our new DI overlords. Quote Link to comment Share on other sites More sharing options...
Mallard Posted October 26, 2012 Report Share Posted October 26, 2012 Were you able to modify the fuel pressure tables in the ECU, like they do on the Ecotec? Others also found on the Ecotec that the problem was with the in-tank pump, so they upgraded that and had no issues. You could also install additional port fuel injection that comes on under high loads, like the BRZ has stock. The tolerances and process of building a DI pump is very tight and I would only trust a company with a lot of proven capability right now. If everyone's going to need them it would be smart for IPS to partner with one of them and control a large chunk of the market. Quote Link to comment Share on other sites More sharing options...
AC66Bronco Posted October 26, 2012 Report Share Posted October 26, 2012 DI..... Have fun with carbon coating up the intake valves. HUGE DI PROBLEM. Plus the new vette is ugly. Quote Link to comment Share on other sites More sharing options...
