I'm wondering what makes more power the HSR or the miniram? If anyone has dyno charts that would be great, it would also be nice to see any picks of these setups.

 

well honestly neither are going to CREATE power for you. Your stock TPI unit is awesome. I have run 12's with the TPI. Now if you go larger cubes or a mean cam set up then a mini ram is greate due to the short runner length. The HSR is awesome too for a decent build that is leaves room for alot of improvement. IMO the mini ram is better pick b/c they are so close in price

 

I plan on swaping in a 383. So which would be better for a 383.

 

Some food for thought.
Be sure to read the specifics on each combo "as tested" they are slightly different.

nice!!!!!!!!!!!!!!!!!

 

Well how wild is the 383 and what are your future goals? I say mini ram for a low 11 high 10 second car and HSR for everything else. Both need special prom burnt chips and tuning so there ya have it. TPiS and look for mini ram.

 

BTW the HSR is FAR cheaper than the Miniram...Much better overall value. Both will support serious HP with an edge towards the Miniram.

 

I agree with the value per dollar and power. But i still say the mini ram will hold up higher horses better than a HSR. I would go carbed out of all these choices anyways

 

Problem is hood clearance.

-- Joe

 

with a camaro it should be fine as far as hood clearance goes.. maybe some mild mods to the support braces on the hood.

i think HSR will support 500hp on a 383. how much higher do you wanna go n/a? theres been a test on all those intakes and the HSR did make 500hp on one 383. i know its possible. seen a few other motors with HSR's that were making well over 450hp judgin by trap speeds/ET's. HSR is cheaper by a good margin.. i wouldnt go miniram unless u get it cheap. i think its overpriced. the LT1 conversion is also a good bet.. very similar to the miniram intake.

 

a HSR may support 500hp.. true.


But with the same long block, the miniram will make more power than both. Even if its a 400hp motor. Regardless fo the manifolds potential in terms of max power, theres a max potential with a perticular combination. My old 355 with a fully ported, siamesed, aftermarket TPI setup was about 400hp. With a signleplane manifold, it was about 460 or so HP. Does that mean the intake's max potential was 400hp? No way, I bet on a more radical, better engine it woulda pulled off 450hp no problem.

You can't look at the max potential for a manifold, you need to look at how they will all perform on YOUR engine. Miniram hands down always wins.

the mini-ram is a 3 inch extention to the
cyl-head's intake port, and then an air-box / plenum...

the HSR is a 4 inch etc.etc.etc.

or not, please enlighten me

 

Oddly enough I fit a HSR under a stock TransAm hood on my 89 GTA. I had to turn the screw clamp upside down so the screw was on te bottom of the throttle body. I eventually would have trimmed the hood brace abit, but the motor started knocking about 1 month later.

This was with stock motor mounts only about 1 year old.

 

I want to get the Golen Engine Service 383 long block designed for the miniram. But I was thinking of putting the HSR on it to cut down on cost. I also don't feel like modifiying my hood though.

 

I'd go with a ported HSR purely for cost reasons if it fit under my hood. Personally, I think an HSR can be ported and modified to flow just peachy. Its about 1/2 the cost of a miniram. However, it just wont fit.

-- Joe

 

If you are going to the trouble of dropping in a 383 whats modifying a hood brace? If you don't mind paying twice as much then go for the Miniram...I'd just modify the brace and put the money to something else go-fast.

 

Hood brace on a corvette? or was that for someone else?

-- Joe

 

I was talking about the original poster, he has a IROC IIRC.

You finally get the Corvette you were looking for?

 

Yeah. i'm in the process of ordering everything I need to do it up right now.

-- Joe

 

very true, i'm just sayin it depends on the power goals you want to obtain. miniram with its shorter runners will usually make more power than the rest on any given motor combo. but HSR should be enough for most ppl's desires. on a 383, with the right cam/heads, i dont see 500hp crank being a problem. that saves you 500-600bucks over new miniram. and with 500hp n/a, i dont see why anyone would need/want more than that unless they were full blown racing.

 

The HSR will fit under a camaro hood no problem if you don't have poly motor mounts.

It'll fit much better than it does on a bird anyways.

 

I think for the price I would really consider an lt1 intake over the stealth ram. You will get the same characteristics as a mini ram at half the price seeing that the mini ram is a rip off of the lt1 intake. I think there is a .5 difference in runner length.

 

why do you keep saying it will not fit...
The past few times you were talking about the C4 hood. Fine we all know it won't fit but grumpy DID get an airbox made that would work, and work very well for the C4 crowd.

As far as under the 'Birds hoods, it is really simple...
you have 2 choices...
A. Cut the hood.
B. Cut the intake.

I choose B and had 1/4" milled off of it. It fits just fine.

 

Got a pic? Also did you have to cut the hood brace?

 

no I did not cut the hood brace.

I will post a link to a thread I posted the pics in.

 

Grumpy_vette made a 1 off airbox to fit his. I can't find any pictures about it, and he hasnt responded to any PM's. Moreover, Joby modified his to fit, and I dont like his results.

HSR = looks neat, efi on the cheap, requires somewhat tall hood.

miniram = performance better than HSR, not very cheap.

singleplane = performance better than all, still not cheap, but requires tall hood.

I had a singleplane on a bird. I cut the hood worked great. Car was soo fast its not funny. . On the vette it wouldn't fit, so I went miniram. If I wanted to modify the HSR lid, and go slower, I woulda went HSR.. If HSR bolted right in for $500 i might of considered it. but to go slower AND have to modify the thing. no way.

-- Joe

 

he has not responded because the company he got to make them went out of business a year and a half ago. Last I heard (3 months ago) he was still looking for another company to make them but has had no luck.

Just cause you think the HSR sucks does not mean it does.
With no tune on it it is better than the stock TPI was hands down.
Had I not already had the set up that I was gonna put into a truck I might have looked at other intakes.
But also considering I got this whole set up minus the commander system for under $400 I highly doubt anything that cheap could come anywhere near this for the money and still be MPI.

I got out of carbs because they are way to finiky when you travel (change altitudes and humidity). MPI does not have that isue.

And no I did not touch the hood brace.

 

He could have at least said "Sorry joe, can't do it anymore." everyone told me "Contact grumpy_vette, blah blah". I tried. I then did my own research. Joby is the only other member I know of that got a HSR to work in a c4, and I'm not pleased with his end results.

My opinion on the HSR sucking is my own, I recommend everyone do their own research.

And the whole setup isn't $400, unfortunately. Even on a camaro with no modifications required to the hood, it's $654 according to www.stealthram.com. Still cheaper than a miniram, and for most people it will work just peachy and is a good upgrade over TPI.

However, this thread is "which makes more power".. Miniram.
