I orginally bought mine for bling appeal. Than I choose to go F/I, JWT kit. There has been no leak issues & I don't have a comparo of the OEM plenum vs. the Cosworth. But I'm sure there were gains.

EDIT: Yes is spent $1500 for a plenum. Its what I wanted. There are members that have invested more into their cars for bling appeal have haven't broke 275whp also.

 

I will be getting a Cosworth Plenum in within the next 10 days. Forged will install it and i will post the Hp gains and differences to answer the question on the Gains for a "low Boost" turbo set up. I am running 8 psi with the greddy twin turbo set up.

 

Were you on forged initial list?

 

Lol im like 32 on there list i didnt get it from forged i have a friend who got one in.

 

Cool! Thanks for posting back to the forums.

I'm looking forward to see how it works out for you.

 

Picking it up this Friday should have results posted by Tuesday.

 

I was going to purchase Eaglegreens Cosworth plenum, but he's still having leak issues. This is his 3rd time I believe and Cosworth has stated that they are willing to purchase it back. This isnt good news for a company that use to build F1 cars. Im still on the edge about purchasing a new one.

 

It will be interesting to see graphs from members other than a vendor's own tests. Right now I want to agree with many to say that this thing flopped. It's just another SSV but in carbon fiber lol

 

 

<~ No leak issues. Don't have a before/after test result. Don't think its a "flop."

 

Minus the leak issues and availibility what do we have

 

injected had it running 20 psi on a gt47r..i think maybe even higher boost... i havent asked greag about this yet

 

Was Crawford willing to buy back its plenum when Eagle blew it up?

 

I feel its a good plenum. Is it worth $1000-$1500? That's up to the buyer. I like opening my hood and seeing...

 

That is sick. That the only reason I would buy it. Im still skeptical about the results. From what Ive seen, a plenum spacer does just as well

 

And I won't disagree with you a spacer might, if not does as well as the Cosworth. I orginally got on the pre-order list when I was considering staying N/A. I knew I wanted the Cosworth mainly for cosmetics. My suggestion for people considering purchasing the Cosworth plenum is; Are you willing to spend $1k-$1500 for maybe 10-15whp in the mid-range to top-end if you're F/Ied. If not, I'd look into a Spacer or oversized plenum.

 

And. there is nothing to refute that this plenum has indeed flopped. There haven't been conclusive tests dispositive of this plenum being any different from the SSV. You ricers will believe anything the sponsors here tell you lol.

 

robertk, your post seem a bit biased. nice engine bay btw, looks good.

question tho, whats with the coupler on the maf tube..........a bit off and oversized no?

and whats with your low tq, looks like supercharger numbers?

what oil catch tank is that?

 

Bias? I think I'm being more than fair. I stated that a $300 plenum spacer does the same as a $1k-$1500 Cosworth plenum. I also suggested that if you don't want to spend $1k-$1500 for 10-15whp to get a spacer or oversized plenum. So I'm confused on how I'm bias.


The coupler just needs to be adjusted. As for my numbers those are uncorrected numbers. That means what is is actually making vs inflatted corrected numbers. Due to being in Colorado (high elevation) the dyno I used automaticaly adjusts for elevation by using a 1.23 correction factor.
