I've been reading old posts about some different EFI systems and I was wondering which is the best, and doesnt cost a lot. I've been looking at the holley stealth ram, the commander 950, the mini-ram, the accel superram, the accel pro-ram. I heard there is a design flaw with the mini-ram and the superram. I've been debating on the commander 950 or the holley stealth ram. Which of these are the best?

The commander 950, or accel pro-ram flows the best. the HSR sucks. The miniram will make power. The superram is a ripoff.

I'm selling my commander 950 because it wont fit under the hood of a C4 corvette. (ditching the firebird), but it fit under my firebird hood with some minor mods to the hood support. (which is required with an HSR anyway).

Be aware, commander setups are not cheap. I'm looking for $900 for my whole setup, which is pretty much plug and play, with fuel line adapters and hoses and all.

how much would I expect to pay for a commander 950?

Base, rail kit, regulator, throttle body, bracket, cable, fuel hoses, saginaw adapters, and the regulator fitting they leave out. Around $1500 or so.

I can't find the commander 950 anywhere. Where can i buy one.

Do you still have this setup for sale ?
Thanks

Nah sold it that week. Bought a miniram for the C4.

I think you should divide it up into two seperate things. One you got the different intake manifolds, two you have the electronics that actually runs everything (which is actually the EFI). They can be mixed matched. So you could run a Holley Stealth Ram intake with a stock ECM that came in our cars (with a custom prom), or you could run a stock TPI intake with a Holley Commander 950 setup (these are just examples). I personally think the budget way to go is the modified LT1 intake manifold and an OEM 730 speed density ECM with a custom prom, but thats just me. For all out performance I would vote singeplane EFI and a standalone ECM like the Commander 950 WB02 or something similar w/ WB02 (could even be DIY). But in any event, you should listen to what anesthes says because he has ALOT of experience with the different setups (much more experience than me!)

What were your issues with that?
Haven't seen anything that bad to make you say that.
Just wondering.

I am running the stock ECM and the HSR is leaps better than the TPI.
Oh, and I am running it on the 'bird and did not modify (cut up the hood) I simply had 1/4" milled of the top of the base.

I would not even consider the accel pizza box.
I have read too many nightmares about working on them.

why?

same question here. the only two intakes i have any experiance with are the HSR and the stock TPI. im still using stock heads, cam, and computer with my HSR but it feels alot better than the stock system ever did

demetri

i still dont really know where i can buy a commander 950 setup for a stock 92 z28

Summit and Jegs both handle them, plus if course, eBay.

demetri

btw can the commander 950 bolt up to a ls1?

the computer itself is able to run almost any engine but the intake that will come in the systems will NOT fit lsx engines

I dont think a comander 950 will control an LSX engine because of the coil on plug setup. will it Doug?

If i remember right, the Commander 950 uses batch-fire, not sequential fire which the LSX series motors use. The Commander also uses Speed-Density technology, and the LSX motors use MAF sensors. Seems like it would be easier to get the Roadrunner from Moates, and still be right around the same price.

demetri

Roadrunner from Moates? whats that, just wondering even though im planning on swapping to a ls1

DJ406

on the LSx motors its the ignition type and trigger mechinism that is the hold back for some ecu's to control. sequential is not the problem its the 8 coil on plug system. there are ways to convert it but thats another story.

I have done a lot of work with the HSR and tuning them. I have found the HSR has one of the nicest torque curves (based on dyno results) for a "not-to-wild or too big" SBC. However, I have also found a number of "quality control" issues with the HSR. Granted this was in the early days when the HSR was first released. Hopefully, they have improved the quality control now. But in on the one's I worked on a few years ago, I would say some of the quality control was a little disappointing.

That would be the biggest negative I would say about the HSR. But, I was very impressed with the TQ charateristics of the HSR (provided the engine was not too big or too wild). BTW, I do own/run a Miniram.

Hey Glenn,

Just how wild or big would you consider too much for a HSR?

My 71 Camaro is running a 406 with fastburn heads, a "moderate" solid roller cam (240/248 duration @ 0.050, 294/302 advertised, 0.543/0.561 lift). It's in the neighborhood of 400 RWHP and running a manual trans. 110-112mph trap speeds as a target (1/4 mile).
