Told ya!! ..11 sec tib coming soon !

Congrats!!...Can't wait till I can take Mine to the next level !!.. ps Messing with high boost in 5th is like playing russian roulette!

I just caught this. The Walbro 450 is an in-tank pump, but did you replace the factory fuel line all the way to the rail? Some of those fittings at the rail and filter get down to 3/16, maybe 1/8" inner diameter, which will bottle-neck your fuel supply.





Have you weighed your car?

 

I hit 11's before the season was over last year. I went 11.97 @ 127.58. I forget what boost level that was at, but I think it was 30 PSI? I was spinning through third with drag radials (225's on the stock 15's).



Crazily enough my fuel system is stock aside from the pump and fuel injectors. I realize I may need to upgrade my lines and theoretically I should do a FPR, but the stock FPR holds consistent and my AFR's are where they need to be. Its something I may need to consider working on once I go higher boost.



Side note: the twin disc should be here by Tuesday, just got a shipment notification . I need to send out my trans internals too, finally got some communication from PAR. God this is costing a lot of money...

 

Racing does that.

 

Whaaa? What do you mean holds consistent? Do you know what your fuel pressure is? How are you NOT at 100+psi with the factory FPR and return system choking a 450lph pump?





The factory fuel lines should be cutting you off by now. I believe the feed line is around a 4an which can only supply enough fuel for 450-500hp.

 

BTW, have you tried contacting Liberty Transmissions? They're in the US, so it may save you the shipping headaches.

 

You'll probably be amazed to know that I don't really know my current fuel pressure. It was always on my "to do" list to get at minimum a fuel pressure gauge. But after speaking with the folks at injector dynamics as long as my AFR stays where I need it there is no point to upgrading. Isn't the stock regulator around 42-44 PSI? I can get my AFR to stay full rich even at 32 PSI on E85, and fine tune it back to where I like it (10.8-11.2:1 on E85). What are you guys using for fuel rails that will work with say an aeromotive FPR? I'd like to run a billet AEM or something to that effect. And yes I agree at this stage (and the next one lol) I'll probably need to route new fuel lines and rectify this problem (oh the joys of being power hungry).



Yes Jon I tried contacting Liberty's Gears multiple times months ago when I first was looking into this, I never heard back from them after multiple e-mails and voicemails. I'd rather not give a company with that poor of customer service my money and trust for a quality product. Besides I think the quality and experience that PAR brings to the table is worth the extra hassle... Remember PAR has made 3rd and 4th gears for this transmission already (for a Korean company about a year or two ago according to my contact). If you read their services information, every gearset gets heat-treated, cryo treated and shot peened also.

 

What I did long ago, was use a 3/8"NPT tap to tap the end of the fuel rail. Then use a 3/8"npt port to -6an fitting on the end to connect a line to the FPR.

However, I believe I later found that the Eclipse rail had the same inner diameter and bolt pattern on the end, so you could use their aftermarket fitting that just bolts on. It's been a long time, so you may want to verify that. Or just tap it. It's just as easy to me. Plus, you'll need to tap the other end anyways for -6an or -8an line, so may as well get the tap.

What you DON'T want to do is hang the FPR on the end of the rail. I did that twice and kept breaking rails due to its weight.

For the rail, I had a local builder make me one out of stock. The stock rail should be large enough for 700whp.





I can't believe Liberty completely blew you off. I recall some Honda guys bashing them though for their customer service. It's probably for the best. Even though the trans is "built", I'm sure you'll be heading back to them for parts. Nothing is bulletproof once in the 600whp range.

 

Thanks for the info sir. I remember talking to the guy at Injector Dynamics when I bought my ID2000's (which work pretty well BTW - I know you had some startup issues with your big injectors), he said I should be good with my current setup to around 700whp. However we never talked about the lines. I was even able to get a tune on 25 PSI with the 2250's in the car on 93 (in case I'm somewhere and don't have a spare jug of E85 with me). The car does idle rich (around 12:1), but it runs and runs quite smoothly. I was figuring they wouldn't perform so well especially with the 30% reduction in fuel when switching back to 93, but they surprised me. I know they are expensive as hell but you may want to look into a set. You need the purple ones with the Delphi adapters (if I remember correctly those are the adapters that go from our rectangular connector to their injector connector). You'll also need to have them send their aluminum spacers to hold the injectors out of the intake manifold properly (for spacing between the rail and IM).



I sure I hope I'm not going back to them for parts! Damn that would take forever and cost a fortune in shipping. I'm only worried about return shipping and getting insurance for $5,000 USD on an internationally shipped item. I may bight the bullet and go with UPS or something to ensure more accurate and timely shipping on the way back. I'm going to want my original gears back too so there is more weight. My brother lives in Australia, perhaps I just need to make him back to the states so he can bring my transmission internals back to me :biggrin: .

 

Although I didn't get the car started initially, I'm sure I could. I didn't mess around with the map long enough. I was chasing oil leaks. I figured I'd let my tuner handle that anyways.



I didn't think about international shipping insurance. Wow, imagine if that got lost, or you had to fight the company over it.
