what makes more sense? to make more power, nitrous or meth injection? both systems are about the same price. I just wanna get the most bang for the buck..tell me what ya think...

nitrous obviously, but you need to use race gas with it so it adds to the cost

if you just want to run more boost w/ lower octane gas then Methanol

methanol is not a power adder, as higher octane gas makes less power w/o more compression and timing

Angelo on here used to have a GLH that ran 14s without Nitrous and 11.7 with Nitrous. It was a log T1 car to boot. There is no way a meth kit could ever compete. Both suck as both require you to fill a bottle. Building an engine for pump gas on the street and you have the power all the time, so for a street car both setups suck. But for a race car just go with nitrous, I believe Angelo removed the IC and saw no power loss with Nitrous. He is the man to ask, I don't think anyone has as much time with it on a TD than him.

Bug him for info ATaylorRacing

My old GLH Turbo ran 14 flat with no NOS and 11.8 at 118 with 150 hp shot.
I replaced the intercooler with a piece of exhaust pipe when I blew the side of it out with a nitrous sneeze (too low rpm usage) and the car slowed to a 15 flat with the same boost as before. The slightly rich NOS shot of 150 hp then m,ade the car in the 12.0 range! The cooling effect of being a bit rich on the bottle...being safe and not melting stuff.

I put 125 hp NOS on my 98 SOHC Neon and it ran 12.11 at 117 compared to high 14s.
I put 100 hp NOS on my 99 Miata MX5 and it ran 12.65 at 109 compared to 15.5s.
I am going to put a 85 hp shot on our Scion Xb and it should run 14.2s compared to the 16.8s it does now.

My set up is a twin fogger deal and can go from 25 hp up to a motor killing 300. I never had any car that had strong enough internals for that.....but a guy that races here at INDY put a simular 300 hp shot on his BUILT 383ci/350 hp 3000 lb Chevy Monza that had run 12 flat, kind of slow for a tubbed out car that is (was) street driven...the results were several passes in under 10 seconds.

JMatt on the SRT forums has a dailey driver SRT8 with a 275 hp 3 stage nitrous set up and has broken into the high 10s with his huge chunk of good looking metal!!!

there is a trick to running with boost because the Nitrous is fighting turbo pressure.

Except for the 86 and newer T1 cars with a 2.2 and light weight rods the TDs are very capable of running nitrous. Most lack Angelo's balls with how much though LMAO. But they can take a bunch. I think a popular unit is the big single fogger nozzle. Like with the 85 GLH, the log intake cars are restricted. Nitrous deals with this a ton because you don't need as much engine flow, little bit of boost and a big Nitrous hit.

I thought you sold the GLH Angelo?

Sold the GLH after a divorce...dang it. :bang head Sold the S60 90 Shadow that I had Kish build too.:bash: I was turboless forever until I got the 05 SRT4, but that SOHC Neon did not need a turbo to run 12.11 at 117, just NOS.:drinking: Since I can't afford NOS refills now I am going to stage 2 and some other mods to get the SRT into the 12s.;)

How much NOS can a stock engine take?
I was thinking that a long time ago the amount of hp our motors could take was the question, regardless of NOS or boost.....some high hp cars were hasving big destruction troubles at 300+ hp with stock internals with large rpm and it was an arguement on did the cranks break 1st or the blocks...I think Cliff Sebring said at a certain point the block would flex and then the crank would break. I never had that problem since I always short shifted when I used NOS. I blew up a rod on old Four Play, no nitrous ever, because I thought I was shifting at 6200 when in reality my AUTOGAUGE tach was reading under by around 1100 rpm!!!:mad:

Always buy AUTOMETER!

The stage 2 is not the answer to 12s, if 12s if high 12s are what you want. The stage 2 kills power running your engine too rich.

I have an old thread in the 2.4 section on the 2 I got running 12.7s. Both run big FMICs, a big item and short tires. Running a 10:1 AF and drowning the engine with fuel is how many stage 2 cars go slower than stage 1 cars.

My brothers car with slicks and a stock computer and boost control ran 12.7 @ 110 MPH, 1.89 60ft. 22 x 8 x 15" slicks

Stage two can (and will) be made to run leaner and it's a big plus to have a 3 atmosphere map sensor. As high as I saw my EGTs go to the other day while continuing to accelerate past 120 mph at 41 I DO WANT a bit richer than the 0 stage I have now.....I let off the gas at 120 mph (WAY past the finish line) when I saw the EGTs hit 1725!!!! My old carb car starts stuttering from being too lean at only 1400!

got a stage 1 here that runs 270 WHP and 380 ft lbs at the tires and 13:2 AF flat as a board all the way up. No detonation. SRTs like 12:1 AF, and thats what I shoot for. The stage 2 drowns you to 10:0 or worse, which is not acceptable. True 02 pipe back 3" exhaust and a big FMIC helps a ton to lean them. I think a SRT with the mex maifold and a hybrid with a stage 2 is the way to go. But a lot more work, but you have a ton of room to go there with fuel

Like I stated, there are ways of making a stage 2 leaner and meaner.:rolleyes:

Yeah you can lean stage 2, what about one of these? Big power?

Making the SRT run lean is a PITA as they have a in tank pressure reg and no fuel return. Bought the divorced reg and an aftermarket regulator for my brothers car, a little too lean to get more fuel. Adjusting fuel is a joke with them. So he started down the bigger turbo path, mex manifold and S60 turbo. It is a far cry from just adding an Accufab to the fuel rail and turning it down or up. Whats your plan for fuel?

The guy doing my work used to work for Chrysler and now on his own. He knows his stuff mechanically and I only know what things might be wrong when things don't work right. He uses some method of bleeds. Several of his customers cars are in the 325+ hp range with stage 2, while I am only shooting for 300+. He has done a huge exhaust on the CSRT4 too and getting mega power from those already. He knows his stuff from years of Chrysler training and hands on work. He did a bit of work on my non-turbo based motored SOHC Neon that ran high 14s on regular unleaded and 12.11 at 117 on 125 hp shot of nitrous and STILL on regular unleaded gas!
