help me pick manifold

I think the spoon is a step backwards?? no?

Unsure to be honest, theres no evidence I've seen to suggest it's a step backwards though.

I thought the spoon design is more for peak gains and thought it would compliment a B20 that is already going to have big gains in low and midrange over the B16B.

All i know is when were have done back to back RR's
We done them twice now with our original header around 15months ago, and then the header we now sell around 6 months ago

First time
TEGIWA 1st pre producion Vs Mugen 4-1 - TEGIWA +3bhp peak, other than that it was very similar

Second time
TEGIWA production model Vs 98spec 4-1 - TEGIWA +7.2bhp peak and it didnt lose out to the 98spec anywhere in the rev range.

It'll be interesting but i'd put money on it not performing as well as ours
 
Were these results after tuning or just a straight swap and dyno ?

I ask this because although I gained 2-3 hp peak with you're manifold when first fitted, untuned the results were'nt great to be fair as I'd lost power in a number of places compared to the stock manifold. A remap eventually sorted this out though and this proved to me just how important it is to have a customised map for you're car once you start modifying it.

If you want to pay for dyno test + retune I'd be willing to post all the results of a Tegiwa vs Spoon 4-2-1. :)

I have no reason to put the spoon 4-2-1 manifold on just yet though due to the new engine and remap early next month.

Would have to agree with tegiwa there. the b20's seem to like big long tube primary+secondary manifiolds like the tri-y designes. Where as the spoon seems to go the other way benig shorter more compact.

how can that be true when the mugen and the 98spec "PROVE" to be the same power the only one iirc that gives more gains is the toda by around 2bhp..

tegiwas dynos are the only one i seem to silly massive figures compared to many others?

so 7.2bhp more than jdm 4-1?

Zen , what was your dyno results after the remap?

peak power isnt everything

It's all here:- http://www.ek9.org/forum/air-intake-exhaust/29147-tegiwa-manifold-8.html

The graph I've posted shows Oem Ecu and Stock manifold against Tuned S300 ecu with Tegiwa Manifold and the results are pretty good I feel.

I could post a graph that shows the Tegiwa manifold with Oem ecu and there are notable losses compared to the oem manifold and ecu around 5000-55000 rpm and 6000-7000.

It was really good to witness the tuning session with Will at RDT and it showed me clearly that yes, it's not all about peak power and just how important it is to have the car mapped by a good tuner.

Not disagreeing with you as you may be right, I don't know.

The spoon 4-2-1 I have is almost a 4-1 manifold as the primaries are nearly the full length of the manifold unitll they merge into 2 then 1 near the end (see below)

What evidence do you have that suggests this would not be favourable with a B20 ???

Ours will beat all the other manifolds listed. The only real fitment issue is that one hole needs to be drilled larger, takes around 5 mins

Has this issue been sorted now? As in, if I order one tomorrow all the bolt holes will line up? Really want to buy one of these :))

Cheers

Hi

Yes i will sort the header out before it gets sent. Pm me once you ahve ordered it

Thanks

Never mind lol. I didnt realise spoon made this type of manifold always thought they only made the 2 piece one. Is that not the 4-1 maniflod ???
