Posted 15 March 2007 - 08:58 PM

ma dadeam putin pe net dupa tuning si street racing si am gasit ceva destul de interesant
am incercat sa sterg preturi si nume de firme(ma gandesc ca nu o fi voie...sau?), acu daca mi-a scapat ceva..sry
postez aceste info pt ca am vazut ca sunt multi entuziasti de tuning

so, here we go:


Basic
Tune up your Car! - Replace the air filter, fuel filter, change your oil(Go Synthetic!), Transmission Fluid(Automatic), Spark Plugs, Cap & Rotor, new O2 sensor, coolant flush & thermstat replaced, check your tire pressure, Run some injector cleaner (I use Techron). Dump in a bottle or 2 of 91% Isopropyl alcohol(rubbing alcohol) to dry out any moisture, it also increases Octane: R+M/2...101 -- Mixtures with 92 Octane Premium @ 10% yield 94.5 Octane
You will be suprised how well your Storm runs when it is propery tuned.

Timing Advancement - advance 2-7 degrees more! (FREE)
-Ignition/Timing advance is the point at which the spark plug fires relative to the piston reaching the top of its travel on the compression stroke, and it's measured in degrees of crankshaft rotation. For example, if initial timing is 10 degrees, the spark will fire 10 degrees before the piston reaches the top of its stroke. The reason that spark advance is important is because engines perform best when complete ignition of the air/fuel mixture and peak cylinder pressure occur just after the piston has reached TDC and begins to travel downward on the power stroke. To do this, especially at higher engine speeds where the spark fires up to 50 times per second, the air/fuel mixture must begin burning before this point so it has time to completely burn and produce maximum power.

Retiming the engine so that the spark fires earlier in the combustion cycle relative to top dead center gives the air/fuel mixture more time to burn in the combustion chamber before the piston begins its power stroke. Firing the spark too late, especially as engine rpm increases, wastes power because unburned fuel is expelled on the exhaust stroke. This is why most engines, especially those with low compression, respond well to advancing the timing respective to the factory setting. By advancing timing in small increments, say 2 degrees at a time, you can usually find a few horsepower.

Similarly, wider spark plug gaps, within the ability of the ignition to produce enough energy to fire across them, ignite the mixture more quickly and reliably. If you’ve got an inductive timing light and a spark plug gapper, you can experiment with different amounts of timing and plug gap until you find the combination that makes your engine happy.

One thing to remember though, you don't want to advance the timing too much, as this will lead to detonation. Detonation is caused when the air/fuel mixture ignites too soon and the power is lost. When this happens, it causes your engine to ping-and cause premature wear and tear on the engine. To keep detonation at bay, you can run a higher Octane level fuel.

Have you ever seen that Ebay "Performance Module" that claims up to 20+HP gains? All it is a 4.7K ohm resistor($0.39 Radio Shack) that you use to bypass the IAT (Intake Air Temp) sensor. This tricks the ECM (Electronic Control Module) into thinking that it is cold outside, specifically 580F. When the ECM senses that it is cold out, it advances the timing 1-2 degrees to warm up the engine quicker. Once the IAT sensor registers that the engine is at normal operating tempature, the ECM retards the timing to the normal 10 degrees BTDC.
Save Your Money! You can do this manually just by advancing the timing, and get even more gains. The 20+HP gains are accurate, if you are doing this to a big block V8 engine. For a inline 4 (I4), you might see 4-5HP gains.

Weight Reduction - Remove seats, spare tire, etc. . . (FREE)
All of that extra weight in your car makes your engine work harder. If you are going to race, make sure that you don't fill your gas tank. Each gallon of gas weighs 6.7 lbs. (6.7 lbs x 12.4 gallon tank = 83.08 lbs.) When I race, I try to have only 1/8 of a tank, and I never fill the tank past the 1/2 mark.

Spark Plug Wires- Anything bigger than 7mm but not bigger than 8.5mm without a performance ignition system. Despite claims made by some wire set manufacturers; no wire set made will increase or add additional horsepower to your engine. Many people have said that engine performance has increased after they fitted a wire set. However, in reality, performance only increased because the engine's potential power was previously restricted by faulty, stock or warn out ignition wires.
Throttle Body Upgrade - From GSi Storm or Impulse)
- The Base Storm TB is 53mm, the GSi is 56mm. That is a 5.66% in flow. Not much, but every little bit helps, that is why they have it on the GSi in the first place. ;-)

Air intake/Cold Air Intake) -
Exhaust Pipe/High Flow Catalytic Converter/Muffler upgrade - 2 1/4 to 2 1/2 pipes

Header replacement- Pacesetter, Stan's(used), or custom.

Test Pipe - Replace the catalytic converter. If you are in an emission controlled location, this is for off-road use only(drag/track), so in other words, don't get caught ;-)

Lowering Springs/coilovers - lowers center of gravity for better handling. It also lowers the drag coefficient by reducing the underbody air flow, in max drop situations.

Strut/Tower bars - Handling - Helps control front frame twist associated with uni-body construction. For better handling performance, this greatly strengthens corner speeds and minimizes understeer due to chassis flex.
Tires) - Performance tires, take your pick as there are a bunch out there.



Intermediate
UnderDrive Pulley Replacement - Unorthodox Racing has discontinued making them for the Storm/Impulse/Elan engines. They have limited Stock on 1.8L DOHC pulleys. You might get lucky and find a 1.6L pulley used.

Aluminum Flywheel Replacement () -
Performance Ignition system +) - MSD 6A or 6AL and GM Blaster coil -Very affordable. You need the Tach splitter cable for this one to work with your tach. If you are not into wiring, get the Wiring Harness.
Jacobs Electronics i.C.E. Pak kit includes the Ice Pak Energy Pak & Torquer Coil - Very Expensive, but the best.

ECM Replacement/PiggyBack kit) - HKS SAFR, APEXi SAFC, Haltech E6GM. I won't mention JET because I have yet to hear of anybody that got this and said anything good about it. So, save your cash on that one.

Oil/Transmission/Fuel cooler/radiator add-on/upgrade)

Performance Clutch - Manual transmission) -

Nitrous Oxide - Dry Setup), Wet Setup NOS / ZEX / Venom Performance / Ny-Trex

Porting engine parts - Intake/Exhaust manifolds)



Advanced

Revin din nou cu aceiasi problema si as vrea sfaturi legate de achizitionarea unui kit tuning pt. GTC. Ieri am cumparat un set de pleoape Lumma si nu mi se par deloc calitative. Alte firme? pareri..Multumesc.

Sunt din ABS ca orice alte pleoape. Fiind nevopsite nu vad ce ai putea vedea la ele decat 2 bucati de plastic. Materialul e neted asa ca se poate lustrui cu glasspapier inainte de aplicarea plastofixului si vopselei pentru aderenta. Toate pleoapele sunt la fel, am vazut pleoape de la KAMEI si au acelasi aspect nevopsite. Pleoapele de calitate ..nu "calitative" ...trebuie sa vina bine pe far, sa nu fie brazdate de linii sau imperfectiuni in suprafata (pori, dungi, asperitati) pt ca se vad prin vopsea. Poti comanda de la irmscher pleoape insa vei avea supriza sa constati ca sunt exact la fel ca cele Lumma.

Dee, crezi ca daca erau vopsite le vedeam altfel? Nu stiu de ce vorbeai despre vopsit pleoape,daca eu am intrebat altceva.Eu pot sa spun ca pe Golf am pleoape si grila de fata KAMEI si nu se compara cu produsele LUMMA.Pleoapele Lumma pentru GTC nu se aseaza perfect pe far, in unele locuri avind distante de 2-3 mm. Iar despre "calitative', asa mai vorbim noi vestici. Astept sfaturi in continuare de la cei care stiu sau au pe masini produse LUMMA, IRMSCHER,MTK...Multumesc.

dee, are pleoape Lumma, vulupe are pleoape Lumma, Aroundtheworld are pleoape Lummasi inca vreo cativa de care acum nu-mi mai amintesc, toti ar putea sa-ti confirme ce ti-a zis dee, oare de ce crezi ca iti raspunde cineva doar asa din "rautate" :( ??? nu e prima oara cand observ ca interpretezi putin eronat ce ti se raspunde :blush:
Farurile de la Astra H sunt facute in asa fel incat nu prea poti sa pui ploape fara luft, pentru ca farul este la fix acelasi nivel cu capota. La G de exemplu farurile sunt parca special facute sa mai ai loc si de pleoape, adivca mai lasate, mai bagate inauntru cu vreo 4-5 milimetri

De unde stia Dee, ca pleoapele IRMSCHER sunt la fel? Are cineva pleope IRMSCHER sau alta firma pe masina? Vreau sa stiu pt. ca as putea sa le dau cele de la LUMMA inapoi, sau sa le vind (140 ron).

In primul rand este un topic de modificari serioase la masina/suspensii/motor.Nu unul de modificari externe.Deci intrebarea cu pleoapele nu isi are loc aici, se va face topic separat.

PUSSYCAT nimeni nu iti vrea raul , Dee in afara faptului ca are si el Lumma pleoape este unul dintre cei mai pasionati membrii, incearca sa fii mai linistita in exprimare
Mai mult decat atat, daca dadeai un mic "search" in care scriai pleoape gaseai acest topic dedicat http://www.astraclub...1625&hl=pleoape.

Deci discutia despre pleoape o continui acolo, nu aici.

As vrea atunci sa discutam de MODIFICARI SERIOASE la un GTC. Vreau sa modific total un GTC de 1,8 140 CP si astept sfaturi legate de modificari la suspensie, motor, produse de firma, preturi, adrese firme tuning,etc.

PUSSYCAT se pare ca nu intelegi ca pentru fiecare topic trebuie precizat un subiect pentru a fi mai usor de gasit si de urmarit.Daca vrei sa deschizi un topic nou o poti face unde vei primi raspunsuri exacte la ce te intereseaza.

Uita-te pe site-urile astea sa iti faci o idee :

http://www.regal-shop.co.uk/
http://www.courtenay...ault.htm?page=3
http://www.thorneymo...ll_Tuning.shtml
http://www.vxrperfor...ntre/index.html

Daca ai sa cauti pe forum la sectiunea tuning ai sa gasesti f.multe informatii, daca tot ai nelamuriri atunci poti deschide un nou topic.

Ma scuzi daca te-ai suparat Pussycat insa iei totul prea in serios si exagerezi. Da am vazut pleoape de la Irmscher pentru Vectra si pentru Astra G. Sunt tot din ABS, acelasi material plastic si vin pe far in functie de forma lui. La varful blocurilor optice ale Astrei H niciun model nu vine perfect pe far. Tu iti poti comanda Irmscher si ai sa vezi ca mari diferente nu sunt daca nu ne crezi pe noi. Dar vezi ca alea de la Irmscher au un pic alta forma. Le poti vedea pe site-ul lor.
La mine vin perfect si cred ca si ceilalti care au Lumma sunt multumiti de aspectul lor si de faptul ca urmaresc nervura de pe capota. Ca au o mica distanta in fata nu ma deranjeaza deloc deoarece este foarte greu observabil.
Daca vrei modificari serioase desigur Irmscher este cel mai recomandat avand in vedere ca e tuner de casa Opel. Poti apela si la un kit OPC aftermarket, original de la Opel care va merge la fix cu jantele pe 19 si care da cel mai bine pe masina. De asemenea poti consulta site-ul tunerului STEINMETZ care are niste kit-uri destul de radicale pt H si mai ales pt GTC care imprima un look super agresiv masinii. Uite link

prima tunare ar fi: evacuarea sport,filtru aer performant si remapare
secondary:kit spoilere
ce urmeaza?...sa o luam in ordine cronologica...
