Hope this isn't a dupe but just saw in the New Summit catalog they are listing a HSR that says it is a direct bolt in for the tpi, uses the stock fuel rails for only $299. I am proably going to go this route and skip trying to put the stock tpi set up in the vette and go direct to the HSR. If it won't fit under the vette hood then I guess I'll have to swap in the LT1 off the Formula.

Two beasts are better than one!

 

can anyone confirm it ,i saw it too and it would be nice to get it and just transfer everything over.

 

Pat

What's up? You following me around the inter-net?

 

I hope it's the real thing. That would be a great deal if it's a direct drop in. Someone needs to call them.

I ran across that today while browsing through my catalog...if only I didn't have to go through emissions testing

 

so is it what were reading that our fuel rails will go on to it without buying theres?

 

Well, that stinks, I coulda saved a BUNCH of money by being able to use stock fuel lines and rails! The part number at Summit is HLY-7540 (299.95) for the satin finish, or HLY-7540P for polished (549.95).

 

well that's a big typo. can't use the stock rails on the HSR. they are not spread far enough apart to go around the base. and the regulator will hit. i've talked with holley on it. and i have one sitting right now on my work bennch.

 

Yep mrr23 is correct - BIG typo. The tunnel ram portion of the intake is longer and wider than the opening in the rails (in their factory configeration). Where there is a will there is a way and you might be able to do some funky stuff to the rails to get them to work (and look terrible doing it), like flipping them around backward, plugging up the factory crossover tubes, drilling and tapping the ends for fittings, etc,, but it's physically impossible for them to be a bolt on.

 

Nitrovette

I remember you from CAC, don't know if you remember me, I don't know what name I used there anymore, but we have a 82 vette that was concerted into a convertible

 

So excited at the top of the thread then my excitement crushed as I kept reading down *crying* LOL

 

yeh i was all excited, WTF!

 

i guess alot of people got their hopes up, as well as i did. thats too bad, saving money would be good.

 

Making fuel rails isn't too hard I've been told.
Fuel rail stock is relatively cheap. Just need it cut and drilled, put some -AN fittings on them.
I think it was $10/foot for the rail stock.
I'll just have my rails custom made since one of my frinds father owns a large machine shop.

 

well thats a real let down summit needs to change that then,and since the stealth ram has been out for a while now why put NEW on it in the catolog.And Jproz1167 i think i remeber you not to many 82's that were converted on there.I mostly hang out at corvetteforum.com.

 

Sorry to get everyone fired up just to be let down. First time Summit failed me.

Building my own fuel rails sounds interesting.

 

call summit, tech support or better yet HOLLEY tech support................(270) 781-9741
they wrote the advertizing copy.... incorrectly, you will require fuel rail kit # 534185 that costs $ 173.69 additional from summit the stock chevy fuel rails and fuel pressure regulator will not fit, the HOLLEY STEALTH RAM and keep firmly in mind the standard plenum will not fit under the stock corvette hood. If you look closely at the upper right corner picture in that catalog on page 33 of the complete stealth ram youll notice the fuel rails are totally differant than the stock chevy fuel rails and FYI, the picture even has them installed swapped end for end in the catalog, the correctly set up fuel feed starts on the pass side rear and the bye-pass line hooks to the drivers side across the front under the throttle body then feeds down the drivers side fuel rail to the rear, the cross-over line is properly mounted on the front between the fuel rails, not as its shown in the catalog.
,look closely DAVID ALLEN from

HAS IT CORRECTLY MOUNTED WITH THE CORRECT FUEL RAILS




NOTICE IN THIS PICTURE THE FUEL PRESSURE REGULATOR IS AT THE CORRECT LOCATION, (DRIVERS SIDE REAR) on this custom stealth ram for daves corvette

 

grumpy thanks for the info,i think itll fit under my vette hood for sure,maybe the throttle body might be close but i can always cut the hood again and raise it some more.whats the total height towards the front.

 

Ya thanks grumpy, good info.

 

just for your info
a stock TPI intake is about 9.5" tall at the rear near the distributor and angles down to about 8.8" tall at the throttle body
a STANDARD STOCK stealth ram is about 10.1" tall front to back and will not fit under a C-4 corvette hood without a scoop
a CUSTOM PLENUM STEALTH RAM is 9" tall as it comes and will fit under a C-4 corvette hood and minor machine work can easily drop that to 8 5/8" tall front to rear for even greater than stock hood clearance
custom stealth ram

custom plenum stealth rams are available here custom stealthrams
your potential gains if any will depend on the total intake system and exhaust air flow,how badly the stock 48mm throttle body was restricting the engines airflow before the swap, of any parts , how well the cam ,intake,exhaust, and cylinder heads match and how well the cumputer controls all the sensor imput/controls, it the TPI INTAKE and CYLINDER HEADS NOT the throttle body are whats the big resrtiction take the time to read the links

http://www.eecis.udel.edu/~davis/z28...age021105.html

 

Have decent TFS alum heads on both so. I'll probably get a LT1 intake for the vette, planning a 383 with a custom supercharger. Won't get the the supercharger till winter 2004 but hope to have the stroker in by next spring. After that I will plan the upgrades for the Formula.

I'll check out those links grumpy, thanks.

 

so how much we talking about here for the stealthram conversion if i already have the tpi unit would i need to get fuel pressure regulator, fuel rails and the SR is that all?

 

i meant HSR not SR my bad

 

Think with fuel rails and adj pressure reg it is about $450.

 

the part number for the HOLLEY ADJUSTABLE PRESSURE REGULATOR FUEL RAIL KIT IS 534-186, summit charges $215.39 for that adjustable regulator fuel rail kit
keep in mind that while an adjustable fuel pressure regulator is a nice tuning aid, the non-adjustable is set at about 43 psi pressure and most stock fuel pumps won,t maintain over 45 psi
so if your looking to turn up the pressure a great deal its not going to be a big change!
try it youself

My stock 60,000 mi. pump supports 52lbs all day long.

 

So did mine until I upgraded heads and added the Stealth Ram. It's more about volume than pressure when the engine wants more fuel than the pump can deliver at WOT 5000+ rpm.

 

by the time you get done converting over you'll spend around $750 $540 for the intake, fuel rails, and AFPR. then you'll need about another $100 in stuff to get the fuel lines to adapt. and if you are fortunate enough to have an 85-86 with the large cap distributor, then you'll need an 87-up small cap. i just found a stock one for $30. then you'll need an intake gasket and different waterneck. the tpi one stick out the wrong way on it.

but overall you'll be money ahead than buying the aftermarket tpi stuff.

 

mrr23,

I have an 86 TPI iroc with the large cap distributor. Do you have any idea how I would go about converting to the later style small cap distributor? I did buy one but haven't tried the conversion yet. Would I just need to buy an external Accel supercoil? I want to convert so I can install the stealth ram.

 

yes the accel coil for external coil will work. you'll need to get the wiring harness that goes from the coil to the distributor also. and get the four wire connector and splice into your existing four wire connector. should be color for color.
