Thanks Leon & wow on the warpage!

Final numbers came in at 399.48 rwhp - 403.42 rwtq

 

Congrats, The better ones are reaching 400/400. Usually a Fast Manifold with a good tune will produce a higher Torque #than HP.

 

I have to say in the 102's defense.
I just got one and had it apart to see how well the lower lined up with my ported 243 heads. The match was spot on. I could only find a few areas that needed cleaning up. Not sure what else can be ported here. I will leave that for Spin to take care of when I switch to the 427 and TF 235's I'm planning. When I went to put it back together It took some real patience to get that top to line up and go on smoothly, but it did and it seated fine. I agree the 92mm Throttlebody just barely fits and you can clearly see the oring. The stock fuel rail dropped right in with no washers needed to the hold downs. I did have to change the orings on my injectors as the 102 uses LS2 size orings and the 92 I had used LS1 size. I checked those spots you said hit the headbolt washers and mine fell right in below that spot. I marked them with yellow wax and installed the intake and there was no mark on that bracing. I have no leaks and car runs fine with no CEL after 200 miles of driving the past two days. It does however feel like it is holding back right around 3k, but at WOT it passes by that spot very quickly. I will try to hit the tuner next week to make some adjustments. Has a totally different air intake sound.

 

The 102 is pretty close port match with TF 225's . The port opening is only 1" going on to the TF's so you wont have any shoulders on the sides of the TF225's. The irony of it all is the 92 has a considerable larger opening and sits lower thus having a good 1/4" shoulder on the 243 base of the runner and a somewhat shoulder at the base of the 225's. I talked to TF about it and they said not to worry about the bottom of the runner because the air flow is minimum and who wants to grind the bottom of the TF 225 just to get A port match. One thing we considered was raising the Floor of the 92 but for now Im going to let the 92's on the 225's in spite of the Floor mismatch. When they designed the 102 they raised the PORT and it looks decent at the bottom. The fuel injectors sit at the exit point of the runner on the 92
and they sit back up about 3/4" inside the 102. The FI O rings will work on both manifolds, just make them well lubricated and those fuel rails will slip right in. I have some pics of the 92 as I had to do some work
with the seals. It runs like new power now but I still think the 102 PORTED wil prevail over the 92.

 

Here are some things that I had to do to the 92's to ready them for installation. Having to remove the 102's and put the 92's back on there
was some repairs and resealing to be done to get it on and running without the cels nagging me.

Pic #1 shows the base of the Manifold from the inside.
#2 & 3 shows where the rubber sealant was peeling away
#5 shows how the injectors are right at the end of the runner. They sit
back about 3/4" deeper into the pocket on the 102.

The dyno sheet is one of the pulls in my attempt to get to 500RWHP. Notice how the torque curve carries over 400RWTQ from 3800 RPM to
6400 RPM. Thats pretty good but it may have come in earlier if I did
not have the port mismatch. The net gain just for the addition of the TF's
is 45 RWTQ and 40 RWHP. Not without a Cost $$.

 

I will have some time till the FAST 102 comes in and is Ported. I am presently putting the DR's on and weather permitting track it this weekend. Check the tires out. What chance do I have getting into the 10's ?

 

Two questions for you before I answer your question.

How comfortable are you launching at 6500 rpm?

And can you bang gears like this?

I can't. Lol.

 

I can launch at 2500 and come out with a 1.90 60. I would have to pull to 133mph to make it into the 10's. The power is there and check out this traction setup.

 

Thanks for sharing the video Joe!


Leon, looks like your going to have fun lowering those 60's

 

Im only going to have 1 real shot at getting a good ET. I'm under no illusion of what it takes to put A C6LS2 NA in the 10's. Having said that
I must try a easy off the line to get a feel for the car. If I get a reasonable hook I will push it hard to get a MPH run. If I would turn 11.99
then I get kicked out because I now need a roll bar to return and that is one thing I wont do to the Car. I know it seems ridiculous having those
TRACTIONMONSTER 305/35/18 R555r2 and not plan to try week after week to get the Car into the 10's but I will feel that traction on the street in 1st & 2nd without that ridiculous wheelspin. I may do a vid.

 

11.49 or faster requires a roll bar unless for some reason your track says 11.99...do a few practice runs to the 1/8 mile to get your 1/8 time and mph then shut off and coast through the 1/4...then go for 1 glory run once you feel you have it down...you going saturday?

 

What would be good in the 1/8 mi. I should be at the top of third ?
would 6.94 be good ? LOL
Really what you say makes sense. If its going to be a real crappy run shut
it down and coast it out. If I can roll it out, stomp on it and not miss any gears I should get some MPH. I have no previous et's to compare it to like
for instance I went 11.95 as a bolton. Put a Cam in it and went to 11.32
@ 125mph. Then I could be looking for that 10.99 near 130mphFiguring I got 45 RWHP / 40 RWTQ from adding the TF's. Its just the kind of reasonable expectency one would have from making changes that have been quantified from others doing the same thing. It will be interesting
.

 

on my 10.58 run i did a 6.83 @ 101.90. so i would guess anything below 7.0 should be good. if it feels crappy get out of it. if it feels good then go for it.

 

Leon you are going to have a disappointing day if you try to use 555R2's.

Trust me I know from experience.

Buy some Mickey Thompsons. Or borrow somebody's.

I like the 315/35/17's better than the 275's, they are better, but they rubbed a little on the highway going over bumps (not at the track oddly enough). It never caused a problem but I need to mention that. My car is slammed with cut bushings, you might not have rubbing problems if you're not lowered. 275's don't rub.

 

 

imo w/o skinnies, you're gonna need atleast a 1.7 60' to go 10s@130+. The DR version of those tires I know have been 1.6s, but yours have the stiffer sidewalls. I believe you have 4.10s, so you should be able to easily launch around 3500 and still pull it off though. Your car should also backhalf(1/8-1/4) in under 4 seconds, so if you can get a 6.9x in the 1/8 that should easily be a 10!

 

I just got word that Comp is sending me a new FAST 102. After a little time to evaluate what happened to the manifold Comp informed us they sent a new one today. I was not sure what approach they would take
in resolving a defect or damage issue with all that happened with the installation and subsequent leaks and cracks that showed up on this one.
I really have HINSON to thank because they were very helpful and quick to
get a favorable resolution in the matter. It is no wonder they have a quickly growing Business and should continue to grow as their customer service is the best.

As soon as I get the manifold back Ill check it out and get it out for PORTING. We will have a A/B test and a good one PORTED 92 VS PORTED
102 same day, same Dyno as fast as I can swap it ouy. Got a little better at that. Leon

 

Great deal!

You get pretty fast at manifolds, I can swap mine in about 15 minutes now if I use an air ratchet. The dyno operator thought I was nuts when I showed up with my own ratchet but he supplied the air and it made the job a ton easier.

I also like to take the hose out of the booster and leave it hooked to the manifold and just snake it in and out behind the oil sender. Trying to hook up the hose to the manifold on the valley is a pain I've found.

 

Yep, got a lot better at changing out FAST MANIFOLDS. Like joe said put that brake line hose on first. Another thing is to remove it with the Fuel Rail assembly attached to the Manifold. Just tilt it and let the Gas come out of the Flex line into A container. Another thing I do is put 1" spacers ( rubber tubing cut ) under the rear bolt heads to prevent snagging going in . you wont get them in once the Manifold is seated. The firewall will see to that.

 

Instead of unhooking the fuel rail and dealing with gas, just put a towel on the windshield, pop the injectors out of the manifold, then flip the rail with the injectors intact back on the windshield.

No dealing with gas this way.
