You might have missed my post on my friend Aaron's turbo nova, or be interested in an update:B4Ctom1 posted:Aaron has been building fast cars on his own since he was a teenager. Mostly he likes to shoot for the stars and do it on a budget. He seems to remember everything he reads and loves to race. One thing about Aaron is, he doesn't like to build anything he can't drive around. He has always driven his Nova around and has no intentions of changing that now. B4Ctom1 posted:two new pics of wastegate work: B4Ctom1 posted:I figure he might run the procharger BOV's. The 7 second pro-5.0 car he just finished for a customer (cage and chassis by Skinny Kid Racing) used two procharger BOV's. B4Ctom1 posted:Here is a letter he sent me as to what he would like people to specifically know about this car and project. B4Ctom1 posted:He started some work on the IC piping. B4Ctom1 posted:perspective from above since search is down and I no longer have archives anyways, I quoted from my similar post on another forum... Anyways 6 months has gone by and its FINALLY running, oh I forgot, he took a little time off to completely do the paint and body work! He is nuts! http://www.youtube.com/watch?v=Z_R7N8KX-08 more to come!

This car is amazing. I was wondering recently if it got finished. I will watch the video of it when I get home. I was wondering why the firewall looks so messed up in the photo where you showed the intake tube that was welded into it (sixth photo from the bottom). It seems to have a ton of ripples in it. Also, can you take a few photos of the engine bay in running condition? Really want to see what kind of pass times this does. Tell him that some dude on the internet really loves his car

I like how the first indication that something is horribly, wonderfully wrong with this car is the enormous goddamn out-jet on the right front fender.

Just out of curiosity, what kind of mileage does he get with E85? Is it any more efficient than a gas motor that makes similar power? Edit: B4Ctom1 posted:Should sound like this: Jownage fucked around with this message at Jul 16, 2008 around 20:20 |

Jownage posted:Just out of curiosity, what kind of mileage does he get with E85? Is it any more efficient than a gas motor that makes similar power? No, anything that runs on E85 uses about 1/3 more by volume (gallons of fuel) to perform the same work. The difference is that in addition to having a higher octane, alcohol is an oxygen bearing fuel with much more oxygen to add to the combustion process, which increases power. Cars that make upwards of 1000hp even with EFI are not really considering fuel economy other than that E85 costs WAY less than race gas per gallon.

With how short that rubber coupling is for the I/C discharge, couldn't there be some concern with vibration transferring from the engine and damaging the welds where the piping penetrates the bulkhead?

B4Ctom1 posted:I believe it is a 106mm, but "I think" he has another smaller turbo for limited competition that fits in its place. Ah ok. Just wondering. What IS the biggest turbo that has/can be used on an automotive ICE? Not counting semis and dump trucks and that kind of poo poo. I think it would be hilarious to open up the cold side and stick some celery or some poo poo in it while spooled just to see vaporized vegetable matter sprayed a few hundred mph.

Beautiful car I'd just like to clarify that a waste gate won't replace a compressor bypass valve, like he thinks (that's at least that's how I read it). When the air hits the closed throttle plate, it will stall the compressor, no matter what is happening on the exhaust side. Ridiculously huge turbo, goddamn. Does he have any more information about BigStuff3 fuel injection? I'm *very* interested in that.

CountOfNowhere posted:Beautiful car It looks like he has a tial 44 waste gate on the cold side piping right before the throttle body. He said that will act as a bov somehow when he lifts the throttle. I dont know why you just wouldnt use a tial bov in the same location. Does he plan on running this car in the USP heads up classes at Bandimere?

CountOfNowhere posted:oh I see, that makes sense... sort of, I wonder how he got it to work On the picture of the throttle linkage, it looks like there is an additional arm on the other side of the bellcrank, connected to the wastegate. I assume that when the throttle is fully open, the arm pulls the wastegate shut; and when he gets off the throttle the wastegate is pushed open, releasing the pressure between the compressor and the throttle. Essentially it is acting as a blow-off valve, just mechanically operated rather than using intake manifold vacuum to pull open the diaphragm. Car looks ridiculous in the best kind of way.

CountOfNowhere posted:oh I see, that makes sense... sort of, I wonder how he got it to work The "waste gate as a BOV" thing isn't his invention, its been done for years by others already with combos of similar levels. Call Precision Turbo and talk to them a bit about a setup like this and they will tell you it is fairly common, and they sell both the TIAL wastegates and BOVs. Also, the wastegate turned BOV is not mechanically operated, the bell crank you see goes to the factory stock gas pedal lever. Pedal lever seen here disconnected:  Pedal lever and bell crank assembled:  I will requote from the post above: Aaron posted:"FWIW, I've been told I DO NOT need a BOV on my car, by both Alex and Brian (no longer there) from PTE. I will be running a Tial 44 WG on the cold side, along with the 60 on the hot side. The 44 will of course act like a BOV when I lift to reduce the chance of compressor stall and damage to the turbo or TB." If you look at the beginning of the video you can see the white teflon line coming up to the 44 next to the TB. B4Ctom1 fucked around with this message at Jul 17, 2008 around 10:05 |

That engine seems to rev conspicuously fast. Doesn't sound exactly like I thought it would when he revs it. That will be an absolute blast to drive I bet

This car is very light. He put the steel doors, fenders, and glass back in it (yes he drove it like that) and he still might have to add ballast to be legal in some classes.

Method Loser posted:Wait, now, did I miss something (probably) or is he still planning on daily driving this thing? really? Sure, here they are cruising with some friends, the car in this post is burgundy one following the black one at 00:45 : http://www.youtube.com/watch?v=EnGarNTG-Kk Here is it running 9.55 http://www.youtube.com/watch?v=-VP_EUNnZuA The black car leading him at 00:45 in that first video is the one in this picture below from my quote above: B4Ctom1 posted:Last year the shop owner Matt completed his Chevelle enough to want to get his 388 motor back. He decided to knock the compression down with an entire rebuild of the engine. Then he topped it off with a Procharger F-2 in place of the nitrous and installed it into his Black Chevelle. Now with Bigstuff3 EFI (since we are a Bigstuff3 dealer) and no more nitrous, Matt grossly overestimated the injector size required for his car. The solution? We reprogrammed the EFI to run E85 instead of gasoline. On E85 on our Land-Sea dyno the car made 983hp to the rear wheels. B4Ctom1 fucked around with this message at Jul 18, 2008 around 00:51 |

I saw on one of those linked pages that this thing has a 10-bolt. The 10-bolt on my Z28 is weak and getting replaced in the next month. Is he just lucky or how does his rear end handle this much power? Am I missing something?

I'd wager that if it's a 10-bolt, it's an 8.5" 10-bolt which was used in bigger cars like the Caprice and Grand National instead of the 7.5" 10-bolt used in the Camaro and S-10
