Dan Plett has recently demonstrated that a Xfire induction system on a an L98 block turns low 14's.
Hope springs eternal.
Or my factory cast Crossfire (ported) manifold on a stock,worn out L83, Crossfire engine, running high 13's. 'Scuse me. Time to fill the oil and check the gas.
RACE ON!!!

Some of you have followed my L98 Crossfire topics. For those that haven't (the short version) I installed a ported crossfire intake with 2" throttle bodies on a stock '90 L98. Altitude corrected to MSL the car ran 13.90s @ 98 mph.
From other L98 TPI topics my ET/MPH seems to fall in the middle of what the stock TPIs are running. On a side note, the et instantly lowered .14 by shifting out of second at 5500 rpm instead of 4800 rpm. (now to fix the 4800rpm forced shift out of 1st.)

The Crossfires are definitely for the DIYers. As far as expense, doing the work in my little home shop I have less than $20 in materials to modify the intake, lid spacer and 2" throttle bodies. A good return on my investment.
:jester Seven years of L98 TPI technology advances/improvements and the engine is up to a whooping 40 hp increase. Of course anyone wanting serious HP isn't going to be running TPI either. :blueangel:
300 hp is do-able.

Have you checked out the CrossFire forum? http://www.crossfire.webhop.net
Should answer some questions you have, after you register.
Good Luck.

You might want to be careful with that high volume oil pump if you're using a stock capacity oil pan.
A lot of people have run high RPM's for a little while and pumped all their oil up into their valvecovers and starved the bottom end. Happened to a friend of mine at the silver state classic thing. He lasted all of 8 minutes.

Yeah, and don't forget about the long tube headers, catback, X-Ram and maybe a stroker kit! :D

Just with the upgrades you are talking about I would say about 270-280, considering the 84 is stock 205HP. If you were to make a few changes with a couple of your mods you would be 300+ easy. But I'm no expert.... :auto:

Re: IS IT POSSIBLE FOR A CROSSFIRE TO GET 350 HP?????????? (Alcee1)
So what are these FEW changes you talk about Alcee1
I know a cfi wont flow THAT great Even Ported. but he is on alimited budget and needs to keep CFI now or go carb and he dont want to go carb.
TPI is planed for down the road but not for awhile....

To your point offershore, today why use LT-1 power and not LS-1/LS-6. In a few months it'll be LS-2/LS-7 technology. Several years ago, you never heard of a Xfire running in the mid 13's. Today, there are several capable of doing it. The guys over at the Crossfire Forum deserve a good bit of credit for getting the word out and providing a place where people interested in building the Crossfire coud swap ideas and tips without being told it was a waste of time. Its been a great DIY project. If you like to tinker and tweak and enjoy the satisfaction of having done it on your own, then do it with the Xfire. :cheers:

I agree. I bought a $10.00 die grinder, $40.00-$50.00 worth of of cutters, and about $10.00 for drill bit extensions. Another $10.00 worth of expoxy to fill the holes where I ground through, and I burned up an air compressor, were MY expenses to port the manifold. I traded parts for the TB boring. By the way, after a few runs with the stock TBs on the ported manifold, I installed the bored (2") TBs. Initially, they gave no reduction in my ETs. I DO believe the are contributing to the cause, at this point. I am shifting at 6000 rpms. I probably have about $1000.00 in all of my modifications, including the Vigilanti torque converter. Good luck, and...

You have had a couple of dozen replys to this thread (we're on page 2), plus a few others. There have been numerous "guesses". You could make this a lot easier if you'd tell us what you want to hear. What ever it is, I'll "second" it.

I have an article on a 1984 vette where the guy did mods and got excellent results, like 12.xx's
I can fax it to you or email it after I find the article if you email me.

Re: IS IT POSSIBLE FOR A CROSSFIRE TO GET 350 HP?????????? (CFI-EFI)
Ok CFI... No one has really came out and said about how much HP just by what i have on the original topic. I have had lots of suggestions and ideas (which I thank everyone for) I just want to make the right decision, and time is getting close for the deal. I only plan on doing this to my vette once and I want to make sure its what I want. So u saying just go do it and let us know how much HP i get from it IS NOT WHAT I WANT TO DO. I am just asking poeple who have been in my shoes I am not trying to be a nag or a pain to any one i am just kinda nervous about the deal and i want to do it right. So if u feel that i am a pain and dont like my questions DONT respond with the comments besides that I am open for any suggestions. Oh ya I am not trying to be a jerk, HEY give me a break I am only 21 lol. thanks
