I kinda hate asking these kinds of questions, but for 1/8th mile racing only, is a 106mm turbo and gear driven F3 on an equal playing field here? Is one more advantageous on the short end than the other? I have a 25.2 LSX 427 275 DR car I'm building and the class I will run allows both, it also allows twin 80's but $$ wise not sure if I want to go there yet.

well i thing a F3 PROCHARGER

I would go twin 80's for the 1/8 mile .

The benefit of the Procharger over the jumbo turbo with your 427ci will be the ability to leave the line with X amount of boost/power vs having to spool the turbo off the line even if you have a 2step. I would think it would make a notable difference in times.

With a transbrake the 106mm or twin 80s would be insane. Otherwise, the Procharger would probably have the advantage.

It will be a transbraked Glide for sure. I suppose thats one advantage of the procharger, no need to sit on a two step building boost pre-staging, but I know they both have their pro's and con's. I'm really leaning towards the 106mm even though I think the F3 would be killer as well, just want to build what makes the most sense for the 1/8th right now, so thats my delima...Twins would rock, just don't think I will go their yet.

We're using an F3 on our new drag car we're hoping to run this year at the LSX Shootout. Bob

106 baby,were going to run low low 7's with the 106 on Phil's car this year

Dam Bob, hell of a build there!!

I somehow knew your answer already Shawn .

106mm all the way. You can spool it off the line. Don't even worry about that. You'll be able to leave as hard as you want to and more.

I think both are capable of making similar power, problem will be with the little 275 which is going to be a more friendly way to get the car out of the hole.

Be easier to leave on less power with the turbo I would think then it will be with the procharger just because boost and RPM are directly related with the procharger.

Packaging with the procharger would be easier I would think, should be less engine bay heat that sort of thing. Turbo won't have the gear drive maintenance though.

This an EFI setup with an intercooler, or a blow thru carb/no intercooler?

Another possible option for the procharger might be the reverse setup that jake's performance came up with, that uses a belt that's about the width of a john force cog, might also be something to look at.

Thanks for that input guys. I have been getting the same advice on the 106 from my friends and racers I know. The turbo off the line may have some more control with boost mapping as far as traction goes, that's true, but I've seen both hit 1.2x 60' on 275's, track prep and proper suspension a huge factor there. Hard to believe the record on a 275 is a 7.5x on that tiny tire, and I mean tiny. I'm really tilting towards the 106 side of the fence, always wanted to do a turbo setup anyway...

with the proper wastegates and an ams1000 boost controller you can really fine tune your boost curve-we got it down to a science on Phil's car,you also have the ability to change launch rpm's without changing boost or vice versa,just alot more tuneability.

Good advice Shaun. I added two 60mm WG's and ams1000 to the list, hard to believe there went another $2K . Suppose I should get the PT 106 ordered up too, what AR do you recommend?

Shawn @ VA Speed

We run the 1.32 last year and debated running the 1.0 to spool at a lower rpm.Running strickly 1/8 mile and on a 275 tire i would run the 1.0.The smaller ar will allow you to spool at a lower rpm and launch at a lower rpm with more boost which the small tires will like,+ running 1/8 mile it really won't hurt the top end

Thanks, we're hoping we get the new RHS block very soon. Bob

DanZ28

iTrader: (5)

I like that idea. I will probably pick up an extra 1.32 housing as well and swap it out for when I do run the 1/4, which I will be doing.

Bob, I'd love hear some feed back on the RHS block when you get it. I might look at that next season if it looks promising..

holy unlimited budget dan, from a simple h/c 347 to a badass 25.2 dr car. rediculous. care to share your secrets. lol

you gotta jump on the bandwagon and go twins.... haha

Very intrested in this as well. With the limited bore, are you planning on overstroking it, or just running a smallish (414 to 430 inch) motor and just boost till it hurts?

I assume the latter being that it's gonna take some RPM to get your project where it would appear you are looking to get to.

Definately have a limited budget, but I made some good investments that took me this far, the stock market put a huge slow down in my progress but I'm geting it done anyway. I'm always looking for a deal now a days though .

I'd love to jump on that twin bandwagon and still might. It was dam cool watching that other car go together . Hang out around some of these shops and you'll be doing all sorts of stuff . I didn't even turn the new motor over and it's coming back apart for upgrades to support the "newest" changes, lol.
