Guest Blazer406 Posted May 16, 2002 Share Posted May 16, 2002 Ok.... tell me if this is a good idea / or if it might work. Take a 8.5:1 350 or 383... put a holley commander 950 MPI complete system...... maybe vortec heads if you want to stay fairly low buck...a cam cut for turbo setup (could even be hyd. cam to keep costs down)..... not too hot.... power range to 6000 would suffice....2 stock GN turbos...(should be able to find these used and relatively inexpensive.... they also have integral wastegate)....2 stock GN intercoolers.....(also easy to find and relatively inexpensive)...... I was thinking about 800 hp @ rear wheels would not be too much to ask out of this combo on pump gas. What do you think? Add this to 2500# z-car and the grin factor just went way up......

Guest greimann Posted May 17, 2002 Share Posted May 17, 2002 I double dog dare you to build it. P.S. Keep us posted with lots of pictures. Quote Link to comment Share on other sites More sharing options...
Guest kc6wfs Posted May 17, 2002 Share Posted May 17, 2002 Hummm, I tripple dare ya... I also am starting my Twin Turbo endevore. I bought 21'st Century turbo book (Dick Datson) Maximum Boost (Corky Bell) TurboChargers (Hugh Maclnnes) Damm, books cost a lot!!!!! But the know how is in those books!!! I am going to do a blowthru type carb design. All going to be junk yard stuff sitting on my nice new motor! My compression is 9:1 1999 Vortec 350 with the good 906 heads. I might buy new pistons to reduce the compression or go with a good alichol injection. I am looking to run 15 lbs boost. And run by the airport for gas every week!!! I'll keep ya posted.

Guest Anonymous Posted May 17, 2002 Share Posted May 17, 2002 First I think you will not achieve the 800 rear wheel HP you are looking for using the parts you would like to use. and unless you have all the stuff to make all the tubing for the turbos, you will spend quite a bit of money not to mention the heat in the engine compartment. I would put the money into the motor and put a big NOS system on that thing. As for the other guys I don't know, but if I was Kc6fs, I think I would put your money in some interior upgrades. I saw your car at MSA show and I thought that it didn't reflect what the picture you have here shows. Don't get offended please, that is not the purpos of this posting, rather lets have the best all around cars to represent the club. I would better understand if your car was in the 10's. Anyway I hope you guys make the best decision. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted May 17, 2002 Share Posted May 17, 2002 I have always like the turbo V8 idea, weight would be more than 2500 lbs with twin turbo's and intercoolers and associated plumbing. Also lets add some things you'll need for 800 hp, compression probably more like 8.0 or 7.5 (you wanted pump gas right?), forged rotating assembly, rods and pistons. A splayed 4 bolt main cap would'nt hurt at all. Forget the Vortec heads, to much money in it to sacrifice using them and they will weigh to much with all the twin turbo' gear you'll want a weight loss. Aluminum heads with probably a larger chamber to get the compression down. Big injectors, serious fuel lines and fuel pressure (don't want it lean thats a certainty). Also at this point you'll be breaking rears, halfshafts and or stub axles. Not being a smart alec here, its a great idea, just the word 'low buck' doesn't apply at that HP level. (Honestly, I think it would be a scary ass car to drive, 90 mph burnouts are not something I really want to do at my age in a small flexy flyer car... ). Good luck though if you decide to go that route, I'd love to see it done, just not rich enough (or ballsy enough) to go for that kinda power. On the above post, I'm not offended, its an opinion. I think where HybridZ members do they're impressing is not at the 'shows' but at the tree, stop lights and/or race tracks. For sure, everyone wants a nice looking car, but for me personally the mechanicals have to be sorted and working before putting money into the paint and interiors. It needs to perform, once thats satisfied, the pretty stuff is easy to fix. Hybrids by they're natures are nearly always works in progress just because much of what we do has not been engineered by anyone but ourselves and as such, somethings need 're-engineering' frequently until we get it right. Just a counter opinion, no offense taken or given. Regards, Lone Quote Link to comment Share on other sites More sharing options...
Guest Blazer406 Posted May 17, 2002 Share Posted May 17, 2002 My line of reasoning is this..... I have seen many turbo regals with stock long blocks/intercoolers run low 12's high 11's on pump gas with the stock turbo. This takes over 400 hp. My idea is to use 2 of their stock setups on a mild V8.I realize that I don't have double the cubic inches they have, but it is not that far off..... and even vortec heads have superior flow to the stock buick heads. Properly selected camshaft/injectors/ ect. should be able to make a difference. I plan on looking at the stock turbo maps, and seeing if it is even in the same park, or if the turbine housing will need to be resized for this combination. I am just thinking out loud.....

Guest kc6wfs Posted May 17, 2002 Share Posted May 17, 2002 Humm first off KennyGZ I know my car is a P.O.S, thats why it's a thrasher car. I never said it was in the 10's, only soon it will be there, even if I have to spend another 5K to do it. I could care less if it was primer grey or black and had dents, it a FUN car!! I did not take offence to what you typed.. don't get me wrong, It is by no means a trailer queen going from show to show, and I have never said it was. Some day it might when it is no longer street driveable because it blows every motor in the 1/4 mile,,,,, hehe Also the interior will get worse in time as the car gets lighter from adding all the goodies, I want little weight, ie it all comes out. Yes it will look like crap. I'll just tint my windows so no one can see in at the shows. Griemann next to me has a sweet car!!!! Inside and out!!! I would love to build a car like that but I would probably gutt the inside out to make it lighter!!!!! Also KennyGZ we should get together since we are so close. call me 297-5188 ---------- Alum heads are ok for turbos but they bleed off heat. Turbos need heat. Cast heads from what I have read are better than alum to some deg. A nice twin turbo can be done cheep and I am going to prove it in due time. I am going to do another web page and going to "blueprint" the way I did mine. I am going to try to do it the cheep way, but if i blow my motor I'll go buy another next week!!!!! It can be done and it will be done.... Does anyone else out here have a TT V8 that can chime in here???? Dave Quote Link to comment Share on other sites More sharing options...
Mike C Posted May 17, 2002 Share Posted May 17, 2002 The Grand National was the first successful, i.e. fast, production turbo car for the mainstream. And not the first couple of years. Why? SFI and intercooler. While you can make the carb work, you'll have more problems than solutions. Turbos are very much reliant on correct AF mixture and EFI is much better suited to changing environmental concerns. That and the dry-flow manifold allows you to still make good low speed power withoug sacrificing top end charge. Turbos rock on darn near anything but "Turbo" and "low buck" are mutually exclusive IMO. Do it, but inject it! Quote Link to comment Share on other sites More sharing options...
Guest Blazer406 Posted May 17, 2002 Share Posted May 17, 2002 I am going to fuel inject it. I was talking about using the multi-port holley commander 950 complete system. See my original post. This should be real tunable with a laptop, and also is compatable with a 2 bar and a 3 bar map sensor Quote Link to comment Share on other sites More sharing options...
DavyZ Posted May 18, 2002 Share Posted May 18, 2002 Originally posted by KennyGZ:.... I saw your car at MSA show and I thought that it didn't reflect what the picture you have here shows. Don't get offended please, that is not the purpos of this posting, rather lets have the best all around cars to represent the club..... KennyGZ, I know you tried to pad what you just said, and Dave is a prince in my opinion for NOT getting offended to what you just wrote, but it did get under my skin and I'm going to vent a bit...don't worry, this will hurt you more than it will me... Here are a few facts: 1) ANYONE is free to run a HybridZ sticker on their Z car, Chevy Impalla, or baby daughter's diaper if they want to. Shoot, I'm Zless at the moment and still wear my HybridZ clothing, plus I know more than many guys out there with 'tuner' cars, so I'll 'represent' this site regardless. Since when was this forum a club??? We have similar interests and a great forum, but when did we incorporate?? 2) Most of the guys in this forum are not made of money, and it takes years to build a car and make it better. I'm still in that process. Telling Dave or anyone else that their rides are less than beautiful is not constructive in the least. Why? We have eyes and can see the difference between what is show quality and what is not. 3) Having a POS Z car is better than NOT having a POS Z car, period. We all wish we had concours quality rides, but that is not reality, especially to us 'poor' folks like me. Now that I have gotten that off my chest, I would just like ask you once again to please pad your posts a bit more judiciously, ok? Gracias.

Guest Anonymous Posted May 18, 2002 Share Posted May 18, 2002 Davy, Sorry you got your panties in wad over this. I guess I should not use the word "club" because "others" might take it as some sort of incorporation. I used the word "club" because that was my impression of this site. I have read numerous postings from various topics and I felt that there was a sort of brotherhood of Z's here but I will say for the record, I was wrong in what I said, On the other hand I never said that everybody here was made of money and I never said that I was either. Also I never questioned anybody's knowledge. I could care less if you know more than other guys that have "tuner" cars. I was only talking to the other guy and I said please don't get offended because I did not want to offend him, rather I know from experience that we can lose sight of other things in the persuit of a lower 1/4 mile timeslip. My appologies to Dave and I will call him personally to express such. As for you, it didn't hurt me in the slightest and maybe you should be considerate of the fact that this is an open forum and people have the right to thier own opinion (at least in the country I live in)in short I will say KNOW YOUR ROLE! P.S. From now forward I will be nice Quote Link to comment Share on other sites More sharing options...
Guest bang847 Posted May 18, 2002 Share Posted May 18, 2002 Dave's alright... he is way too easy going! when we were at Tim's place and Tim spotted a fuel leak Dave was like "I guess I'm gonna have to buy gas on the way home!!" Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted May 18, 2002 Share Posted May 18, 2002 Like Tim said, lets just chill out about this. I met Dave at the MSA show (super nice guy), and I personally know Kenny (can't say enough good about him), we are getting side tracked off the subject. I want to hear more about TWIN TURBOS, 800 HORSEPOWER, SLAMMIN TRANSMISSIONS, and TIRES BEGGING FOR MERCY!!!!!!!!! LETS GO RACING!!!!!!!

Scottie-GNZ Posted May 18, 2002 Share Posted May 18, 2002 OK, hope we are back on track. I am curious to know how you are going to mount the 2 GN I/Cs. There is a guy with a really nice and quick El Camino with a GN drivetrain and 2.5 GN I/Cs!!!. Actually the 1.5 is the result of an I/C being extended with half of another I/C. He has that one in the stock location on the engine and another as a FMIC. Car makes phenominal power. If you are interested, I will see if I can get a photo. The one thing I agree with in this thread is the fact that you cannot think 700hp and low-budget. Do not forget that the mods to the chassis/suspension to support 700hp is going to hit deep into your pocket also. Quote Link to comment Share on other sites More sharing options...
