We just finished fabricating our prototype S2000 ITB cold air intake box. :foto:











:hyper: Can't wait to put it on the dyno tomorrow!

*1st round results*

Before the ITB's and the AEM tune he had CAI, Header, TP, and catback exhaust and made 194whp on our dyno!
The day after install he did a trackday at Portland International Raceway, he said "Today I had a track day at a local track and I could tell a night and day difference from when I tracked without the ITB's. The expanded power band and the throttle response allowed me to run some of my personal best lap times. On the slower turns where i'm out of the power band I noticed that car accelerates quick and is back in the power band. I ran the car pretty hard on the third and fourth sessions, the car did not experience any heat soaking at all on the track. Air temp outside was about mid 70 in the afternoon. "

good lord.. thing looks awesome and to complicated.. lol specs on what throttlebodies were used?

 

Nice, how do you think a j's tsuchinoko/pwjdm style intake would perform combined with itbs? Rather than just a surge tank/induction box with intake arm?

 

^ probably not that great considering the connection with the airbox covering the itbs being small. now if it was wide enough with a filter to match it would b a different story.

still dont think it would be that much better than this set up/or just running itb's with filters. this is all opinion though.

 

Isnt the whole idea to help increase airflow? This design seems counter productive. If you made the opening to the ITBs Flush with the intake, so the air didnt have any obstructions to get into the ITB, the air would flow a lot smoother and should increase the cfm.

 

In for numbers.

Bunch of Thermo Nuclear dynamics airflow characteristic scientist in here.

Obviously thats not a real title, nor is this a real final product. PROTOTYPE. You have to start somewhere. And this may work. WHo knows.

 

yea trackforged = fail... not in just the stuff they make or do but overall bad customer service, ripe off prices, and had a few friends go through them unsatisfied. seeing this wasn't a surprise.

 

I've heard nothing but great things about forged, especially their customer service. There prices for s2000 parts are up to pair when compared to other companies. Unlike other companies, forged has forced induction kits AND NA kits that theyve developed. As stated earlier, I've seen nothing but positive feedback from real customers with real products from forged.

 

Nice....waiting for the dyno results

 

 

Hey thanks for all the feedback guys! Got the results this is just the first round we're going to get CAD'd and it will evolve over time.



During tuning we did the majority of the tune from the start with the CAI off, it was making about 220 then we closed up the CAI and it pretty much instantly made the power on the chart above. Before the ITBs and being tuned on AEM (when the car was still on the stock ECU), he made 194whp on the same dyno. We will have an update in the next coming weeks on further progress as well as compatibility with other kits, this was done on a reworked OBX kit, one of our other regular S2000 customers has an AP2 with the Hayward/Jenvey kit so we will test fit his soon.

Sweet!!! this is great for it only being a prototype!

 

The main purpose of this was actually to lower intake air temperatures without sacrificing the natural flow of the itb's. Compared with the numbers from other itb cars we have done it seems that flow has not been compromised, it is challenging to get a large plenum in this area with the low hood height of the s2000. Lets not forget also that airflow near the firwall of most cars is almost completely stagnated without proper hood venting, so this should work well in supplying a constant cool-air feed.

I saw an average decrease of about 9 degrees celsius when compared back to back with the hood down. Granted this is on a stationary dyno, but high speed airflow can only make things better with the inlet location of the plenums intake. I would like to verify that the part itself does not increase horsepower, but as we all know colder air is more dense therefore we did see some gains with the cooler intake temps.

I look at it as a way to take some of the negatives out of itb's, less around town noise, a good cheap high-flowing filter, and lower intake temps. Not to mention having a plenum gives you somewhere to actually monitor intake temps properly wich helps with tuning.

I love the design and nice numbers.

 

R&D in progress getting some non track miles put on right now, so far no complaints
