You ready to throw down some serious cash? All the best parts and precise machine work with some big twins will get you there.

Aside from the motor, you need a purpose built chassis & drivetrain if you ever hope to get that power to the ground. And I'm only talking about a drag car - road-racing that thing would just be stupid and pointless.


Wait....you want to drive this thing on the street too??? I think you need to set some more realistic goals for something that will be street driven.

 

Yea mine used to get warm too. I carried a box fan with me to the track and ran a drop cord to a small generator and would open the hood after a run and let the fan cool the engine. I hit it with a 250 single stage shot the last time I went to the track and it got very warm. I would say in the 240 range. I then pulled the engine and sold it.

Yea paper thin cylinder walls + excessive heat from turbos + no efficient cooling system that can handle 1500hp = Kaboooom

 

Wouldn't you fill a 1500hp block anyway?

 

I wouldn't know......

not a big deal with a dart block and thats mostly all I ever see when I do anything at the shop. Or a ford eliminator or the aluminum one. There is a 814 being finished up going in a brand new jerry bickel first gen mustang 2200# so it should see 200+ easy and go 6's. Guy also has a 770 to test with. Its a sheet intake with split dominators etc. etc. 100k motor

 

this thread is making me want to build another 383.

 

Look up Project F-Bomb and the motor built by Nelson Racing Engines. I wouldn't use an Impy to do it, but other than that, taking a 454 LSX block and throwing twins on it shouldn't be a problem considering you are looking to spend $100K. There are plenty of reputable shops that will be glad to take your money. You say just out of D-Town, is that Dallas, Detroit, Denver, etc?

 

i understand what your saying. When i read posts about people building stuff i see other say all the time "what are your goals" "what do you want to do with it" "how much money you have" i have gone over that in my head and have answerd those questions in my thread. i read threads over at www.digitalcorvettes.com. theres guys over there that are making 1000+ in daily drivers. theres a guy right now building (2 actaully) a LS based motor witha dart block. he going for 1,200 hp with a turbo going to spin 8 grand and last 100,000 miles..dont beleive me? heres the link http://www.digitalcorvettes.com/foru...highlight=DART
My GTA had about 450 at the crank and another 150 on juice so i can handle power, it took me a few runs to get used to it but im confident in my ability not to stomp in through the floorboard the first time i get into it

 

thats what the adjustable wastegates are for..ill have them fully open untill i feel "comfortable" upping the boost. ive driven some nasty cars so im not some dude going from a corsica to a corvette lol..the way i see it with the gates fully open it will "only" be making 6-700 hp. about 100 more then what my GTA had..that and the impy weighs 4,500 pounds it will be rougly the same speed..

 

Im going to build one once my LT1 goes, but its only got 45K miles so its going to be a while

 

read that thread i posted..these guys drive 1000 horse vettes on the street daily without any problems.. i dont see a problem with cooling it.

 

guys comon read a little first..i said 1500Hp set on "kill". which menas max boost, max timing, full race out setup..probly wont see that but a dozen times a year..kinda like havein somthing a little extra if i need it ya feel me.

the wastegates will be open 99% of the time while its drivein on the street. that means itll make 1-2 pounds of boost if that, run very conservative timing and make "only 6-700 hp" which imo is pretty common nowadays

i know all about neilson racing engines..i saw there video he had on youtube with that 555inch twin turbo in a chevy 2 i think it was..he was like "we have the boost turned way down to about a 1000hp..2000 is a bit to much for the street" lmfao

 

i chose the impala becasue i want a full frame car. i was thikning about a monte carlo ss but imo i dont think its strong enough. the motor that was in my GTA i put in my caprice and it ran real good. ran mid 12's with 450 ponies.


What do you guys have against an impala>?

 

were gonna try to order a ZR1. SHE insisted on that idea lol

i came up with 1,500 becasue theres a guy buling a 427 turbo LS based motor using a DART block..i was looking for more inches so thats were 1,500 came from..keep in mind it wont be making 1,500 99% of the time

 

Even with a rollcage 1500hp gets a little dicey in the Imp chassis. Once I thought about it more I know another guy with a car that likely makes maybe 1300 or so, full weight, lots of stock parts on the car. Converted Donovan 434 to accept all the LT1 specific stuff and a blower for the boost, boost is fairly low maybe about 15psi with a small shot of nitous to cool it. Car makes enough power to trap mid to high 140s, between breakage and traction issues he is only getting mid 9s out of it though, and he did a minitub on it to get more rubber under there. It is still stock style suspension.
Maybe the craziest thing about the whole thing is he is using the OEM engine/tranny management, the 4L60E and 8.5" 10bolt have to round out the top three craziest things he has kept. It is street driven and dragged, don't think it will road race though, the suspension work needed to get this kind of power to hook in a straight line usually wont corner well. For example they use an antiroll system that keeps the axle and chassis dead parallel, at low speed cornering it feels good but try and push it and the rear will suddenly break away because it is like having way too stiff a rear swaybar, bet if you had stickey enough tires you would actually lift the inside rear tire in a hard corner. For fast cornering you need some articulation.

There is a car in Sweden that comes close to what you are looking for too, this one a blower actual LT1 block, runs high 9s, lots more work in the rear suspension, like Fab9" and 4 link, BIG boost numbers high 20s-30, he actually does all you want to some degree. Appears to me DEEP pockets built that car, aftermarket management, 4L80E with seperate controller. Running the weight and mph numbers this may be about 1000hp, nowhere near the 1500 pipedream you have.

quickss is a good friend of his and could add more about the car.


I don't think you have any gasp of what this sort of thing takes, both of these guys are a bit older, wiser and more experianced.

 

I have an idea for you, go to the chevy dealership and get a SS full size truck. Get yourself a nice trailer, then go buy a dedicated racecar. You will still have money left and you will be better able to enjoy them for what they are.

Honestly, that kind of hp will twist a factory impy in half and just about any other factory car for that manner. If you have the coin like you say your coming into build the body style you like and let your chassis guy figure it all out. A project like this is going to take considerable time (read about 1 year) if you want it done right.

A good friend of mine won the lottery (24 mil.) and he started projects like the one your describing except using corvettes, he finished 2 of the vettes (each with over 1100 hp) and honestly they are not "all that" and they are very underperforming for the amount of hp on tap. He has a new z06 vette and he loves it compared to his project cars, its much cheaper to insure (try insuring a 1100 hp vette at replacement cost), he can drive it anywhere and not worry about if it breaks who will fix it. For example the brakes on his vettes are the same Brembo brakes used on the Ferrari F40, to get a "basic brake job" done is $4000.00!!!! and that with him doing the labor.

Building high end cars need/get high end maintenance just remember that when starting a serious project, It takes big money to build them, drive them, and work on them.
