I will have all supporting mods. What am I missing besides a built block once I get a cop and manifolds?

I'm sure I won't be disappointed with 450whp. When I build the block I'll go bigger I want this EF2 for spring. I have a big block nova I'm hunting and I feel this setup is going to do it.

 

Ahh thats right, I remember them not being same as stock. What I mean about it not being smaller, is that its on the same playing field as the green. Very similar in power but the EF2 packs a better "punch" per-say. Its definitely not a competitor to the 71HTA. LOL.

 

Nothing wrong with 450. I know this will seem like blasphemy but if it were me, and I wanted that extra above the 450-500 range. I would prolly go nitrous. Pound for pound its the best power adder. I used to run alot of nitrous setups on my V8 builds back in the day. Not only do nitrous cars make ridiculous torque(on stock block case obviously would choose higher RPM for activation for this case) but on boosted cars the "HP rating" for the nozzles generally makes substantially more power than on an NA car. In some cases (especially on a great system like AEM EMS you can build a dry nitrous timing/fuel maps, external triggers, etc.) you will most likely double the rating. So that 50 shot on a boosted car effectively can become 100+ WHP!

As far as the supporting mods goes, well thats a bit of a grey area because to my knowledge no one has made 500+ WHP on the evo 8/9 version of the turbo so its kinda hard to know. If I were to take a guess (other than your fuel mods) I would prolly go with SD, external dump, 3" downpipe, headwork, proper tubular manifold (shearer, JMF, Toxic Fab etc), and 30+ pounds of boost.

Just a guess anyways.

 

I'll refuse to use nitrous in my Evo. If I had a V8 I would consider it but I just don't see it worth it for me personally. I'd rather buy a built block from Buschur or MAP and at that point I'd probably go with an HTA 3586. I am going speed density and I along with an old timer at work are porting my head this coming weekend. This nova has a 454 punched out 30 over, 4:11 gears, some fancy torque converter and Hoosier slicks. He's making around 450whp as well. I'm running GForce T/A's and this mods list. It'll be close but I feel I'll have him. Also to note I'll be running a Competition stage 3 flat disk and I do shift incredibly fast to be perfectly honest. As for manifolds, both of my stockers ported will flow good until I'm up at or over the 500hp mark and by then because of the route I'm going I'll go to a twin scroll tuber.

I'm excited as hell about this EF2, I'm choosing that over the EF3 simply because It shouldn't lag at all, I want maximum responce on my stock block it should be an ideal setup for road coarses and the drag strip.

The 1050s are for sale, probably going with 1450's I just want to talk to Emery and a couple others before making my final bite on the fuel setup. Thanks for the info guys, it's appreciated.

 

Nitrous isn't very everyone. People got the wrong stigma about it generally though. It won't blow up your car with today's controllers and systems. That comment might have been true maybe 30 years ago. It is just as safe as boosting your car IMO. However to each their own.

A 450 WHP American muscle car is actually quite slow especially on street tires. You should have absolutely no problems beating him.

 

I have a "Bottle's are for babies" sticker haha

 

I'm wondering what an EF2 would be capable of on my setup since the one posted on MAP's website didn't mention having an o2 housing, had BC cams, and was a MAF car.

My build consists of...

 

IDK about megan o2 housing I gained little to nothing with mine maybe slightly faster spool... Probably something decent with a open dump would make a significant difference?

 

I wouldn't put a dump on my car. I have had the Megan installed longer than I have had a TBE on the car so I don't know what gains I got from it.

 

ya ya.

 

I don't believe were looking for significant gains from the Megan O2 alone as much as simply not bottle necking the setup. Once you start flowing 25-30psi and every other part of the setup flows freely, having an O2 or running the stock one makes a significant difference BUT I also don't see an advantage in running an O2 dump over a Megan O2 at these power levels on a stock frame EF2. I think the Megan O2 is ideal on these turbo setups.

 

Hmm, I understand about it bottle necking up the exhaust, but I was always informed open dump would pretty much eliminate that issue. So your saying dump would release to much back pressure on a stock framed turbo? makes sense I guess it just depends on the setup

 

You just really don't gain anything with an o2 dump until you're running an ef3/fp red or larger turbo.

 

Well I guess I should have been more specific yeah the ef2 perhaps it wouldn't be sufficient to run it like that, I was mainly thinking about ef3 in my case but yeah your absolutely right.

 

instead with EF3 what are the main benefits ?
is it a must ?
