Is it possible to run 11.99 or better on my setup here..... - Page 2

What they say is that most of the hardcore people are starting to use 2g heads now.

Wrong. I have seen 1g and 2g venom SMIM. The 1g is huge and the 2g sucks. Look at a stock intake manifold gasket. There is no doubt that a 1g will flow better. The 2g SMIMs are the same size as the gasket still, a hell of a lot smaller that a 1g. Unless you want to spend ~$500 on porting, a 1g head is a lot better.

Stock 1g head has easily ran 10s on many 1g AWDs. So has a 1g intake manifold. Heck, even the old 1g Al Blaha MAF ran mid 10s. Oh yeah....they were on the same car. Al Blaha (and a few others even) ran 10.5 at 132 with only 2g pistons in his block too. His block was never out of the car.

As for myself, I have personally ran many 14b cars to mid 12s on race gas and my own car ran mid 12s on pump with 11.98 as a best on race gas. So 11.99 should be fairly easy with a good setup like yours. Biggest factors.....driver and tuning. You have the equipment.....(BTW, Curt Brown ran 10.7 in his AWD on a FP Green....or 50-trim no NOS).

My avenger ran 8.11 @87 mph on an 1/8th mile track. With alot less mods too... 560cc evo 8 injectors, stock engine/head, and a 20g with a cracked turbine housing.. (8.11 would come somewhere around a 12.6 1/4th) So, I would say you should hit that 11.99 for sure with your mods

Yes it is possible, but not probably for a few reasons, the fact that you don't know where you stand, is very concerning. Get some track time in, get some dyno time in, then try to figure out how close you are. Maybe your a phenominal driver and will crack it on your first try, maybe you suck ass and will need a t-78 to crack 11's, thats something you won't know until you try it at the track.
I am sorry, I don't mean to insult you or diss you, but it is possible with your setup, the only things that are the 'unknowns' are: tune, track, and driver.
good luck.

UPDATE: Well I just ordered the Magnus this morning from ExtremePSI. I just went ahead and did it before the price went up. I will have it by Wednesday. I'm tired of dinking around with deciding what to do.

As for tuning..... I think i a pretty dam good tuner and driver. Computer Networking/ Programming is my job so i'm used to figuring stuff out. I just got this GSX car in late August and have no track time in it. I did very well at the track with my old and sold '97 GST.

By the way those who are thinking about buying a Magnus for a 2g, the new $715 price does NOT include the bellmouth velocity stacks. I called. That's another $220 option!!! I copied all the specs of the Magnus from another member on here but i thought i would just get (one) so i could reverse engineer it some more in detail. My brother is excited and wants to machine/manufacture one of these. We own a large shop with a CNC lathe and CNC mill. I would like to manufacture something like this for less cost WITH the bellmouths if anyone is interested. I ordered the 2" tubing for the runners and the 1/8" sheet aluminum to get us started.

is 14s with a s16g an accomplishment? I suppose it was FWD. Im not bashing, just curious since most people dont run FWDs.

How many axis is the CNC mill? I should be finishing the CAD work on my intake manifold design this week and I need to get some stuff made. I could probably even send you a working (or close to it) CNC program. Which controllers are on them, fanuc?

Onefast99gsx · 02-19-2005

Hey Jet, the CNC lathe is a Lynx 210L with a Fanuc controller/panel.

The CNC mill is ironically a Mitsubishi V500 3 axis mill. It has Yaskawa servo drives.

3 axis is plenty for our everday applications at the shop.

I know you said you worked with like 5 axis machines. Those would be nice for things like head porting and such.

SlowWhite · 02-19-2005

Glad to hear you went a head and bought one. Just need some cams and your'll be good to go!

I would have never spent the money on a SMIM. There are other things that could have probly gone for. When you pull the stock intake off, look at the size of the runners into the head. The magnus is going to be no larger. Look at the size of a stock 1g mani. That is dam near the same size as the head. I would have gone the cheaper route and bought the 1g head in Rochester, MN for $75, got a 1g mani for $25 and a 1g TB for ~$65.

The only point I see you getting it is for the business. If you can mass produce a similar design and make good money on it, more power to you. Just not how I would have gone.

You might want to read up a bit on velocity and fluid dynamics. Huge ports don't mean huge power. The 2G Magnus was a wise choice in this case.

**Halon** · 02-20-2005

It's not the size of the runners that's so important in top end, but more the length of them. 1g manis have long runners, which is why they do very well in the midrange. Pretty much better then most of the aftermarket ones. But the aftermarket ones blow away the 1g manifold on top end, because of their 5-6" long runners.

I don't think I'll be buying a Magnus now. Those prices are getting too steep for me. I'll probably go for that JM one, or unless someone elses locally looks to be nice and worth a try, then maybe that route. Congrats on your buy though. Did you fork the extra money for the bellshaped stacks? If you don't pay that extra little bit, are the runners just flat against the bottom of the plenum, or do they still protrued in a little bit?

**JET** · 02-20-2005

A 3 axis will be all I need for my project. Send me a PM and we can work out some details. I used to work on a Citizen Swiss 9 axis machine that ran 3 program simultaneously. It has been quite a few years since I ran a Fanuc, but I think I can still do it. Where in WI are you?

john · 02-21-2005

I think he can make it without spending the assload of money on the intake mani. If he wants to rev to 8500 or something it may be another story but he would have to do more (springs and retainers) to even think about that. If I were him and planning on reving to 7500 or so, a 1g intake mani will keep the party going long enough. We will see though if I get my car dynoed how quick it tapers off. I am a little bigger than a 50 trim.

**JET** · 02-21-2005

A 1g intake manifold starts to puke at about 6500 rpm on a higher HP car.

**JET** · 02-21-2005

Well, Craig ran a 14.1 in his $1500 laser and a 14b. It has a boost controller and 3" turbo back on it. I don't remember if it has a UICP or not, but I don't think so.
