I'm considering making a new thread to see what the smallest/lightest/gentlest turbo is. I don't want to build the engine or cram psi into it until it explodes, all I want is a little push. It's a question where the answer most likely is, "What's the point?" because I don't want massive numbers. But at the same time I don't want a grenade. And as you all know, this is an idea, more than anything. It's like not a viable concept even with good answers because all I do is think, haven't acted on anything to this date.

The smallest, lightest, gentlest push is a supercharger.

Oh that would be fun!!!!!!!!!!!!
Since half of the FI guys never leave that section they would have no clue what was happening. If only I didn't have my self imposed no playing in the tech sections rule.

I think you just get a phantom ESC. If you only want like 20hp I don't see it being worth the work to put all the parts on for a turbo. Also a little turbo will max out way too early and might throttle the engine

If you really want to keep it simple:

I think I'm going to get.5"polished steel rod for that one post. Use washers to center it in the frame

Go 3/4. The 1/2 may flex.

I don't think so but the cost will be negligible

A supercharger will get you 240-350 at the wheels, depending on the pulley size. Because it's belt-driven, its RPM rises as the engine's RPM rises, which means a relatively smooth boost in power. Contrast this with a turbo, which is spun by exhaust gases and adds power in a rush as boost comes on. Turbos can get a LOT more power; I think the record is 650-ish on the stock block. But that doesn't sound like something you want. Keep in mind that above 300 bhp, the engine will probably hold up, but it may not. Above 400 whp, 4th gear will flex on its input shaft and shear off teeth with hard usage.

Heat management and fluid management become extremely important with either, or even with a high power NA build. A better radiator, an oil cooler (air to oil is most effective), ceramic coat or wrap on exhaust, vented hood, crankcase and pcv catch cans, more frequent fluid changes, etc... None of these are a part of the cost of the kit; they're all extra. Once you get high enough on FI you also need to worry about fuel delivery.

Maybe consider an NA build. Talk to CSG Mike about ACE's headers; you can get half the power of a JRSC just from a header and a tune. And if you go with a flex fuel kit, you'll get even more.

I've had the JRSC if you have any questions.

While I appreciate other responses to this question, and others of course, this is probably the best response I've ever gotten to any of my ideas, ever.


Honestly, going turbo has always been last on my list, usually filed under "nope, don't want." I only asked this time because a friend said something about using a little one and I thought that would be viable. But Gram here has basically summed up my previous thought paths. I've always thought if I went FI, I'd go with a supercharger, and that's still on the table. But most likely what I will do is an NA build. Full exhaust, drop in air filter, flex fuel, tune. That should net me around 200whp which sounds like plenty (from what I've read anyways.)


Other things I've considered a light bits like lighter pulleys and a carbon drive shaft, but I've always been iffy about those.


Andrew, I'll be sure to keep you in mind if I decide I want a supercharger.

Love my aluminum drive shaft

I'm not saying FI is bad. I would love to get an Edelbrock SC. But I know that the cost of the kit is only the entry fee, and I'm shortening the life of my engine significantly. To me that tradeoff is not worth the fun it would bring. Meanwhile an ACE CS400 and a tune will get you 200 whp on its own. If you run E85 with a properly tuned flex fuel kit, you're looking at 220-ish. E85 has its own quirks, which would need a lot of research before I did it.


Lightening the rotating mass is a great way to get more of your available power to the ground. I would read up on pulleys though; they may not be the best way to go. There's still the flywheel and driveshafts that can be replaced. Also look at drivetrain bushings. Power you spend flexing bushings could be put to the ground instead, with the tradeoff being higher NVH. I've done most of the bushings, except for engine mounts, and I'm happy with what I've got.
