I have read alot here and talked to some cool guys like carrol supercharging.
But some things are still bouncing in my head.

I'm trying to make a ultimate daily driver, decent power... ON MY BUDGET.

I picked up a 87 Corvette with a new motor, and a 700R4 in it. A Carroll Racing Supercharger kit without S/C off ebay with WI,30lbs injectors & 1990 PCM to boot. I have also picked up a Novi 2000 gear driven head unit.

I'm going to engineer it all together. with different injectors into a 1973 Wide Body Vett.

I'm thinking 7 psi, water injection etc.

Question Since I'm blowing through, is there any sence in porting the intake.

I know that everyone screams it sucks. But I have read a few articles of 450hp with a stock intake. ???????

I'm hoping the sc will fix the intake prob.

Now the question is heads. How do I need to work the alumium heads over? And how much power will it inprove?

Any advise besides search. Been there and done that.
Not spending anymore besides mabe headwork, tune, and self porting intake.
Thanks

How much power do you expect. This is a huge S/c, larger than I need. spec for max of 975hp. I'm hoping for 400Rwhp +.

 

Short version.

I have a 1973 widebody vintage race vette. A rebuilt corvette Tpi motor, Novi 2000 Head unit. WI, intectors,(will tune), 1990 PCM, 58mm tb, upgraded mild cam, 255 fp, headers and dragpipes.

I think the heads may be after market. They are very shiny, unlike the stock ones...... I'll check later.

Do you think I can get a reliable 400hp to the ground?

OR would it be better to sell the S/c and just hook my wet NOS kit on it?
All I want is a dependable 400rwhp. I know you can fart in a carb and get 400 NA hp. I hope a big sc can acheive it through this motor.

I have swapped, ebayed , and cragslisted this whole ordeal.
any quick tips.

 

Heres the car.

 

do you need to port your intake to get 400rwhp? no, not if your using a supercharger. BUT if you do port your intake, you can run less boost and make the same power, or run the same boost as before porting and make more power.

 

Whats your compression?

I would guess youll need bigger injectors

And for tuning- look into code59.org and get a WidebandO2!

 

I got a Aem WBO2, Carroll said he has a chip that converts so you can tune with tunner cat? Or one of those. I may not have all the details straight but something like that. I'll look into it as well.

As far as compression I'd say stock. Unless those are aftermarket heads. Then I'm not for sure.

 

with a little time and being creative you can do it.

I have a novi2000 in my vert. on a 383 lt1

 

This is definately a budget garage build.
I've given 5600 for the 73 shipped to the door.
2700 for the 87 shipped to door.
1100 for supercharger stuff.

360 for an extra TPI.
150 for two fuel pumps.

I plan to swap the 73 motor and tranny into the 87 with the extra TPI.

and sell for 3500.
corvette rims for 100.

$1000 for paint. I'm going to do it myself this time. (Cross fingers and pray for me.)

i sold my 99 SS to make this happen. So the budget is spent.

But if it works out, it will be cool to have a old school split bumper fixed up with supercharger for $8000.

There will be alot of work though. But time is money and I have plenty of time. LOL

 

Sweet, I would love to see some pictures!

 

Since ive searched a million times for the same quetion (Intake porting + boost) Now my opinion, is if its a stock heads and cam motor, Porting isnt very necassary. If its a higher lift cam, and warmed up, or aftermarket heads. Then Yes, Port the heck outta the whole intake and find some SLP runners. Or TPIS runners and base. Reason i say this, Its about the power band. stock heads and cam, will better match stock intake restriction (for lack of a better word). If youre adding more lifet and air. You will need more RPM. And more RPM will spin the blower faster for more boost. But IDK, i could be wrong. search my posts in this section, You should find 1 or 2 interesting threads.

 

i dont mean to be the first jerk to say it but this is a thirdgen camaro website
not c3 or c4 vette ...
they have there own website wich you would most likely have alot more luck with help doing the swap im sure alot of guys here dont mind helping but you should check into the vette forums ..i know there is a c4 forum my father is on it for his vette

if i can get a link for it (im at work most stuff is blocked) ill post it for ya

 

I think this forum is probably the closest thing to an authority on TPI forced induction that he'll find though. Most of those corvette guys with TPI cars are more interested in wiping dust off the car than performance. And I'm glad to see a C3 with a tpi setup.. really looks right in those cars.

 

x2,

and heres a picture of my novi for ya.



LOTS HAVE CHANGED since then. alot cleaner and looks good now. more info on it in sig.

 

Do yourself a favor and port the intake and other stuff while its apart, even if everything else is stock you'll only help things along towards your goal. I guarantee the Novi will put a smile on your face, ask me how I know If my welder ever gets his butt in gear I'll have my turbo setup done, looking good TPI383

 

not to sound like a jerk but how is this a widebody vintage race vette?

This is a vette w/ aftermarket ducktail spoiler and mudflap type fender flares. original race cars used L88 flares.

This is a wide body corvette:

 

This site has more info on TPI.

 

Thanks.
These parts are aftermarket for guys who wanted to race and build there car as they could. The front is a aftermarket with no flip lights. The flares and front allow a much wider stance and tire package. More simular to the grand sports of the earlier C2.

As you can tell the tires on mine look retarded. And the picture was angled to try and hide it. My rear body parts are Baldwin motion. and the front and hood, who knows.
Mine is more of a Balwin motion style.

The one you posted is more of a Greenwood style. I always thought they where ugly. But each to their own.

I'm more into drag racing than circuit. Baldwin guarented high 11's. And they had a more streetable style.

 

Placement of the blower will be tricky, especialyl since the upper a arms are in the way.

Read this, may give you some ideas (of both the fail and other stuff):

your in the same boat as me. I need to get off my *** and do the cold side pluming.
Also need to put in a Th400 Just killed another 700r4 behind this 383.

 

It is definately going to be tricky, thanks for the link.

My brother has a 90 corvette we are installing a used Procharger setup on. I'm going to see if I can fabricate a bracket like it, and extend out bolt tubes to mount to since mine is opposite rotation of his.

I may post the novi up for sale.... And pick up a procharger head unit, since my brother already has a bracket I can mock from.. ........I just hate to not use the Novi.

 

There is a guy on ebay that has a shop, he claims he can build a really tough 700r4. ???????

I'm not sure what tranny is in mine right now. I just want the mpg witht the overdrive. But I want it to be reliable.

I bet the 383 is a complete monster.........

 

The mudflap style flare is a design by Ralph Eckler, sold by Ecklers and copied by others. The original racing L88 flare is now sold by ACI, they copied them and I have those on my cars. Those were the initial wide body race parts, later replaced by the Greenwood Widebody panels for even more wheel clearance and improved aerodynamics.

The black & white pic is an original Greenwood cars w the latest style widebody panels. I have a set of those but an earlier design with the curved transition. They are much wider than the street panels found on the Greenwood GT & Turbo and copied by ecklers for their turbo II

These are my cars w/ the L88 flares





The fixed headlights are also a Ralph Eckler thing. Originally the L88 race cars had aluminum buckets w/ lexan covers. The greenwoods had the ones in the pic above w7 the buldged lexan covers

 

Nice!..........How deep are your rear rims on the green one? Who makes them?
The Cheverolet on the hood is a nice touch.

 

It's an effect paint, from the side it has a green hue.

The "chevrolet" is on the air cleaner, there's no hood on it in that pic.

The rims are 18x11 but they are too narrow, need 18x12 They're Intro Pentia wheels
