Edelbrock E-Force Supercharger

The exact reason I'm looking more at the Edelbrock.
Just waiting for first round feedback!

Waiting on kit as well for our 2014 Monogram FRS

Will release info once its ready.

After the kit is out and running, I'd love an apples to apples comparison between the Sprintex 210 and the Edlebrock. Heck while we're at it add in the Cosworth and any other positive displacement charger. I'm thinking the Sprintex 335 is a step above the Edlebrock but if I'm wrong add that in the comparison. I need to be convinced with facts before I sell my Sprintex 210 for another unit or just upgrade to the 335.

Based on blower size you'd be wrong there. TVS 1320 is a 1.32l/rotation while 335 is 1.46l, however max RPMs for the Eaton is 20K while the sprintex is (I believe) 15k This gives a slight edge to the TVS blower assuming efficiency is comparable between the two setups.

Take a look at what the 'out of the box' TVS 1320 units are doing vs moto-mikes 335 dynos. That 335 is just a beast, but maybe those TVS units have a ton more potential in them.

Yeah the 335 stuff has been impressive, but I don't think anyone has received an edelbrock yet for testing and the only dynos are CARB setups running on green pisswater. moto-mike has 93 and no such emissions restrictions.

Very good point, although I think all he's been trying to do is dumb the thing down so it won't bend the stock rods! I'm definitely interested in what the TVS 1320 can do - I'm a big fan of the TVS units and have been asking for one for two years now

I'm just getting up to speed on this, and it's really exciting to see such big players offering bolt on SC kits for these cars. I'll be saving my pennies.

Cosworth/Edelbrock/335 is in a whole different league from the 210.

On paper, the TVS 1320 is supposed to be able to flow more, while simultaneously being more efficient; for now I'd give the (slim) edge to Cosworth/Edelbrock.

I don't forsee a Cosworth kit in California for me to test and log anytime soon... but if you guys can round up a volunteer, I'll put it through its paces and publish my findings.

My sprintex 210 on 91 octane only made 10-15 more whp than my current NA setup (ACE header + E85)...

Like @CSG Mike said, completely different leagues.

Interesting. Mine made about 60hp ish more compared to catless UEL non-supercharged setup. I guess you are on E85 without the supercharger compared to supercharger without e85.

I guess I was thinking the 210 may be closer because the CARB kit from Edlebrock is only making around 235whp compared to my 210 kit making over 250whp or so.

All forced induction kits will be limited on pump gas. They reach a knock threshold and then need higher octane to make more power if they have the flow capacity to do so.

The edlebrock is much bigger than a 210 and thus with more octane can safely make much more power. Carb tunes of JRSC and Edlebrock will be conservative and consistent vs. a (I assume) custom tuned setup like yours.

Even when I was turbocharged, I was limited to ~280 whp on 91 octane. E85 unlocked 400whp on that same kit. On the 210 I was limited to 222 whp on 91 octane. Never tried e85.

Add e85 into the mix and the 210 will reach its flow limit before any of the other mentioned kits.

So basically swap engines (no replacement for displacement) or run e85 if I want more power is the basic moral of the story.
