Default 2point6's update

Some of you may be interested in my progress to lower my times further in the 12's... Yes, I know this is the Prelude section but those who know me understand why I post here. For those who are newcomers, hold your flaming till later.

I have made some new changes to my current set-up, which I believe will help me solidify my 12 sec passes for those who think I just got lucky. Let me explain... People doubt my legitimacy based on 2 things, My E.T. (12.94) and trap speed (104.77). There is a lot of speculation because many claim my trap speed is too low... well, I base this "low" trap speed on the poor gearing of the M2B4 trans. During these passes, I was shifting into 4th close to the finish line, putting my RPM's relatively low (around 6000 RPM). To remedy this I recently aquired a T2T4 tranny. The different gearing should help increase my RPM's through the traps. I already experimented with smaller slicks, but my 60ft times slowed from 1.8 to 2.0, however my trap speeds were up almost 2.5MPH. I have yet to put the tranny on my car, but will expect similiar results in MPH, but hoping to pull even quicker 60ft times. We will see soon. I will be out at LACR for testing in the next couple of weeks as the car is in California working on my next modification.

Collective Racing has teamed up with Iceman. We are currently developing an intake that actually works. Flow results are already superior to a similiar 3" AEM CAI. The flow characteristics and the insulation properties of the plastic will make this product a hot item for those looking for every edge over the competition. Currently this intake is desinded in mind with the 90-93 Accord in mind, but we will be developing this for the Prelude owner as well. For the NOPI event, a special "Air Force" ram air induction will be made (for the Accord) which preliminary testing has showed well over 1.2Lbs of boost at 80 MPH. Believe me, this makes a difference on the track. This "Air Force" system and Accord intake will be exclusive to Collective Racing. They will be sold as "Collective Racing edition by Iceman". There will be other H22/H23 parts availible soon including an intake manifold.

OK... enough with my sales pitch, other changes to my car will be in the form of a rear difuser that will keep my rear bumper from acting like a giant air brake as it currently does.

With all these changes happening, this makes my car even closer to an all out track car which I have been avoiding. The car is still functional and I intend to keep it that way. The changes will be subtle, but should make a profound difference in my times. We will see. I will keep you updated for those interested.

Are you serious? 1.2 lbs of boost means that you will be seeing 16 psig in the manifold. If that's true, then that is a fascinating product. I would think good for the street as well.

1.2 LBS in the intake manifold. This "Air Force" is like similiar Iceman ram air set-ups that replace the passenger headlight. I would say this is more suited for the track. The cold air version will be better suited for the street. Both options will be availible.

I heard the T2T4 transmission had the same gearing as a stock F series. Thats the transmission I unfortuantely got stuck with after a shipping issue, that is, a stock F series M2L5 - and i've always heard it's slow as ****.

Any elaboration on this? Is the T transmission, though with the same gear ratios, built stronger or something? I always heard F's aren't built to deal with anything?

Very interested to know, Ive been hearing my f's gonna crap out since its mated to an h22

Thanks, sorry for newb question or something

T2T4 tranny is from an F20B, Accord SiR-T

It has the same gear ratios as a fifth gen prelude, except is has lsd.

Pretty much every gear in that tranny is longer than the M2B4.

Awesome man! So I take it you're finished w/ the motor for now?

The rear diffuser should help out a bit. On a high-powered Civic hatch, going from rear bumper to no rear bumper got 2-3 tenths off their 1320. And figure maybe 6-10 HP for the ram air intake, you should easily pull about 3 tenths off your 1320 time!

Awesome man, keep us updated!

This engine is finished, but I have others in the works. As far as the diffuser, I am trying to make it look good rather than just cutting the bumper away. I like keeping my car looking like a car. The ram air should work killer, but testing will be hard to do off the track, so dyno figures will be vague.

I run 12.9X at 103-104 mph all day with my h22/M2F4. People that question the mph don't know **** about drag racing.

The 1.2 lbs of boost is a figure from the Civic "airforce" product...
The CB-7 Accord has much more 'real-estate' therefore the frontal area is larger... In theory, this should force even more air into the system than the Civic possibly creating even more boost...

Just a thought tho

Good Job Scooter!

Why would people question a 104 mph in the high 12's on an NA car??

You were on slicks, right? That immediately gives you a lower trap.

Back in my racing days, there was a pretty consistant measure of a FWD H/A car to get a sense of where they were (on slicks).

98-100 you were just breaking into the 13's (me in the Type R)
100-103 you were deep into the 13's with the 103 guys around 13.2 usually (Sgt and Lip when I was racing them)
104-110 you were in the 12's and the 110 guys were sneaking into the 11's (Sgt and Lip when I was out of the racing scene)

So your time was very believable. If you were claiming that on street tires, there would be questions .........

I just finished installing the Circuitworx/Prodrive FD in my T2T4 tranny. I don't have my car, but should have it back early this week. I will keep you posted.
